   Pruning bougainvillea

   I have a potted bougainvillea that has lost a lot of leaves and the branches that lost those leaves have dried up and died. It also has a fair amount of new growth in other areas – making the plant quite spotty. (some new growth some dead spots). What should I do so the plant is full of new growth?

   Bougainvillea blooms on new growth, therefore takes well to pruning. You can prune in late fall or early spring as well as light pruning throughout the growing season this will stimulate new bushy growth.

   Pruning Bougainvillea

   We live in Houston, Texas. Our very mature bougainvillea has always bloomed great. But is was getting out of control size wise. I pruned in back hard in late March, after our last freeze. The leaves have all grown back, but no flowers yet (we usually had full flowers by now). Will I get flowers this year? Or did i prune too hard or too late?

   The best time to prune is right after flowering. They can take light pruning all season long. If your plant is overgrown and you need to control the size, early spring before growth begins is a good time to hard prune. After a hard pruning bougainvilleas tend to stop blooming and put on strong vegetative growth in which they can produce thorns instead of flowers. Try a “bloom boost†fertilizer to encourage it to flower.

   I live in Southern California. I have a bougainvillea (red) in full sun. It’s at least 30 years old. I tried to get it to extend over a porch area by allowing branches to grow in that direction. After several years, the branches got woody and I get very sparse leaf growth. Can I prune back to the wood on these long branches (maybe 15 ft) to promote growth, or should I cut them off and promote new branches to cover the area I want?

   Hard pruning cutting back 1/2 to 2/3 should promote new branches and a fuller bushier plant. This should be done before new growth starts in early spring. Keep in mind that hard pruning will make the plants stop flowering and go to a vegetative growing phase; producting lots of green growth and perhaps long curved thorns in the leaf axils. You can apply bloom boost or better bloom after heavy pruning to slow down the vegetative growth and encourage new flower production. A soft pruning such as pinching the tips back to shape and direct growth can be done throughout the growing season.

   Can you share tips on dividing Bougainvillea. Mine is quite large (pot size is 2′ and I am worried it is getting root bound and would like to divide it properly) thanks

   Divide your bougainvillea in the spring at the begining of the growing season. Water your plant a few hours in advance as this will make it easier to remove the plant from the pot. Carefully remove it from the pot and with a sharp knife cut it into sections. Remove dead and tangled roots . Be sure to use fresh peat based soil and clean containers. Plant it the same level that it was growing before. After repotting trim away 1/3 of the plant vines, this will give the roots time to grow and keep up with the leaves. If you can’t repot, topdress. To topdress scrape away the top 1-2 inches of soil and refill with a fresh soil mix. The top layer will provide extra nutrients to the roots

   I am in Phuket, Thailand and would like advice on care of Bougainvillea in this climate which is tropical. I have an automated 10 min twice a day sprinkler system for the garden and the soil has good drainage.
   My gardener is watering the leaves of my plants – is this a good idea?

   Hi Carol
   Bougainvillea do well in a tropical climate. They thrive in full sun and heat and bloom best when kept slightly stressed and on the dry side. They are heavy feeders and should be fed regularily with 1/2 strenght fertilizer to keep them blooming all season long. As far as the automated watering.. twice a day may not allow the plant to dry out and will keep it in a moist state all the time which will encourage new growth but no flowers as well as root rot if kept too wet. You cannot water a plant to your schedule, you have to water according to what the plant needs especially in the rainy season. Overhead watering is not the best idea-it is better to water directly into the soil. If the wet leaves don’t have a chance to dry out by evening then they can develop diseases such as leaf spot & powdery mildew.

   NO BLOOMS

   We planted a Bougainvillea last August in our backyard. We live in Mexico in the mountains where there are some very beautiful Bougainvillea plants. It bloomed right away but hasn’t flowered now for some time. It looks like it may have bugs because the leaves do not look healthy-curled and shriveled. However, I did notice that there is some new growth. Should we spray it with a pesticide or leave it and hope for the best.

   Hi Jessica
   It sounds like your plant is in the right environment. Here are some cultural suggestions that it needs to bloom. Bougainvillea require at least 6-8 hrs. of full sun. They respond to blooming when they are slightly stressed- crowded roots and the soil kept slightly dry. In addition, blooming occurs on new growth so a light pruning will stimulate new growth and at the same time eliminate the diseased leaves. Lightly fed your plant 2-3 times a year with a balanced fertilizer. In general, lack of flowering usually happens from not enough sun, too much water, too much nitrogen. There are also varieties of bougainvillea that bloom in the fall in response to short days. If the insect problem gets worse, then you will need to identify it and treat the problem.

   I got my bougainvillea in Florida and It was in full bloom. We planted it in the yard in M.S its very tall now but has no flowers what so ever but has alot of large green leaves…and lots of thorns, other than that it looks good! Just no blooms.

   It may be the new location-not enough sun. In addition, they bloom under stressful conditions; need to be root bound and dry. The rootbound part is difficult if planted in the ground but you may be able to control the amount of moisture(unless its raining all the time). Let it dry out between watering to much moisture will promote green growth and no flowers. If your plant is dry, try using a bloom boost fertilizer to stimulate blooming.

   Propagate bougainvillea
   can you cut off a branch of the bougainvillea and get it to root….what is
   the proper way to get it to root from a
   cutting? thanks

   You can propagate bougainvillea in the spring/e. summer when night temperatures are above 55degrees. Take softwood cuttings with 5-9 nodes, strip the lower leaves that will be in soil and dip the ends in rootone. Sub-terminal cuttings (tips removed) seem to work better than tip cuttings as they are less prone to disease and rot. Insert the cutting into a sand/peat soil and place in a plastic bag (to maintain high humidity) in the shade. The soil should be kept moist and not allowed to dry out. Bottom heat of 72 degrees is suggested to speed up rooting which should take 6-12 wks. Bougainvillea can also be propagated from hardwood cuttings (bare stems) in the fall/winter and will take 3-4 months to strike roots.

   Color change
   I have a large pot of fuschia boug. that I bring inside every winter. I get two bloomings inside. I took it outside this spring and it is now raspberry/red poppy colored. (Which doesn’t go with my hot pink garden) How do I get the fuschia color back. Miracid? Thanks

   The change of flower color is affected by several factors: temperature, amount of light, quality of light, ph and micronutrients in the soil. Low temperatures, more light increase anthocyanin which is the red/purple pigment in plants, conversely high temps, less light decrease anthocyainin. Ph and fertilizer also has an affect on the shade of red. Try the Miracid and see if it changes the color. Let me know what happens.

   CAN I MIX SOIL AND EPSON SALT AND BUT TO THE ROOT OF THE BOUGAINVILLEA FOR FOOT?

   Epsom salt is a good source for magnesium and sulfur. According to the epsom salt council studies show that these micronutrients make plants grow bushier, produce more flowers, improve phosphorus and nitrogen uptake and increase chlrophyll production. It is usually mixed with water and watered in (2 TBLsp to 2.5 gal water). It should be used carefully, too much can also cause problems. Eventhough epsom salt may do some good, the better way to fertilize your plant is to provide a well balanced fertilizer with micronutrients included.

   Color change
   I am trying to pot perfectly red bougainvillea. I’ve been told B. Karst is best and have bought a few. Have noticed that when brackets are young they are red and then mature to a pinker color. Is soil ph an avenue to explore to keep them on the redder side?

   The color of flowers will naturally get lighter as they mature, It’s possible that ph will change the color but other factors such as temperature, amount of sun and nutrients also have an affect on color. Try lowering the ph ad see what happens.

   Pruning bougainvillea
   I have a Bougainvillea that survived the Katrina flood. It’s been almost 2 years and the plant is bigger and more beautiful than ever. I want to move it to my new house but it is growing in a wooden tub that is about to fall apart. What is the best way to move it. Will I ruin it if I cut it down before transporting? I has spread all over the back yard. I would love to move it as is but it seems impossible. Any suggestions?
   Rosemarie, St. Bernard La. Now in Hammond.

   You can cut it down before you move it to make it more manageable. They bloom on new wood and can be trimmend anytime. It sounds like you will need to transplant it into another container so pruning will help the plant readjust to the change. After it reacclimates itself and shows signs of new growth give a a feeding of 1/2 strength fertilizer to stimulate flowering.

    Wintering bougainvillea

    I have 2 beautiful Bougainvillea, I live in the very north east of Louisiana, can they be planted in the ground? Or do they need to remain in containers?

    Bougainvilleas are hardy in zones 8-10, you are in zone 8 on the marginal end of hardiness. You can plant them in the ground. It will tolerate temperatures as cool as 30-40 degrees but will need protection or it can freeze and die. Plant it on the south side of the house

    .

    My husband and I bought 4 plants in hanging baskets in Winston Salem, NC. I want to keep them in pots but I am not sure they will grow in this climate. Any help is much appreciated. Tammie

    Bougainvillea is a tropical plant and is frost sensitive. It grows in zone 8-10. You are in zone 8. They may go dormant during the winter and drop their leaves. You may want to protect them from extreme cold by keeping the baskets in the garage and watering slightly just to keep it from completely drying out. The important thing is to keep the roots alive so that they regrow the following spring.

    Hey, great site. I live in Bali and I have 2 mature Bourgainvilleas which I recently repotted. Unfortunately both have responded badly with all leaves falling off and new ones emerging only to die off a few days later. I think the roots may have been damaged in the repotting exersize. Can anyone offer any advice on how to recover a plant with damaged roots.
    Many thanks
    Russell

    Your bougainvillea is suffering from transplant shock. The important things is not too stress the plant and in time it should recover. I would cut back the stems up to 1/2 so that the roots don’t need to support so much top growth and have a chance to regrow. Be sure the soil is well-drained and don’t let the plant dry out. Since you have new growth and they are heavy feeders, fertilize with 1/2 strength of 20-20-20 to stimulate growth or try a root stimulant. Keep the plant in a slightly shaded area until new growth perks up and then move to a sunny location.

    PLANTING BOUGAINVILLEA
    I live 30 miles west of Houston in the Fulshear TX area. In early November ’07, I purchased 8 beautiful Red Bouganvillea plants already trained up in tree form. Ranging from 6 ft to 3 ft heights. They are in good healthy condition and blooming. They currentlly are in the large plastic containers I purchased them in i.e., 65, 35 and 20 gallon containers per tree size. I want to plant them in the yard in full sun. The grower told me to use super phosphate and Lime to neutralize the alkalinity of the soil in this area to treat the holes for planting. The grower is located over 100 miles from me. Two questions. How exactly do I go about treating the holes for planting and should I wait until spring to transplant them in the ground in this climate area. I still have them in movable state in the pots. Any tips for protecting my investment appreciated.

    Bougainvillea are hardy in Fulshear, Tx (zone 9). If planting outdoors: Bougainvillea like a slightly acid soil with a ph of 5.5-6.0. Not knowing what your soil ph is, I would dig large enough holes for each plant mix in some organic compost (which will provide some nutrients ). Be sure the soil is well-drained. Space them 36-60″ apart. Water the plants well and add a root stimulator-such as superphosphate to encourage new root growth. Keep them on the dry side after they are established. Since bougainvillea are frost sensitive, you may get some winter leaf drop or the plant may die back completely if the weather gets too cold. Plant by a southern wall and be sure to protect the plants when temps drop below 40F. It’s better to wait till spring to plant them so that they can have a full year of growth to establish a good root system for the winter. Lime is used to increase the ph in soil. So if you have an acid soil with a ph of 5.0, then you can add lime to increase the ph.

    I live in Singapore and have got 2 pots of orange bougainvillea plants on my balcony. They get healthy amount of sunlight but are not growing well recently. Despite fertilizing and pruning, the new leaves come out wrinkly and remain so even when they grow bigger. I’m not sure if it’s a problem of over-watering or if there are bugs (no white spots so far though). Pls advise!

    Distortion of new growth is usually caused by several factors; aphids, thrips, virus, herbicide or ethylene injury. Check your plants closely for insects. There is also a cucumber mosaic virus that causes the leaves to become distorted and mottled.

    Cold damage
    Bougainvillea care
    I am in Orlando, FL. My potted bougainvillea was flowering beautifully until a frost. I moved it into my garage for the cold nights but it still dropped a lot of its blooms and leaves. Now the blooms are coming back, but the leaves don’t seem to be. Should I just leave it alone, or fertilize, or prune, or what?

    Leaf drop is a typical response to cold temperatures. and winter damage If you still want to enjoy the flowers leave it. It will releaf when it warms up. If the plant looks straggly cut it back up to 1/2 of the stem to get a bushier and fuller plant. Prune in Spring before they sprout and fertilize when new growth begins.

    I live in Spain and now have an apartment with a garden. The soil is clay. Our neighbours have several bougainvillea that are only two years old and are thriving and in full flower even though their garden gets just as waterlogged as ours. I have bought six bougainvillea but after two months they have dropped all flowers and leaves and all that is left is three foot stems on each plant.
    What do I do now? I would be grateful for any advice.
    This is the best site I have come across after days and weeks of searching.
    Trish

    Hi Trish
    The clay soil may be a problem because it doesn’t drain quickly and will hold water longer. Bougainvilleas like a fast draining soil too much water can kill the plant. You could ammend the soil by adding more organic material such as peat moss, compost etc. or plant them in a raised bed that will provide better drainage. Eventhough, your neighbors soil looks the same, it may not be the same and their plants are established. Your newly planted bougainvillea needs time to regrow new roots and get acclimated to the new environment. During this time they will drop their leaves and flowers because the roots cannot feed all the foliage. They also have a tendency to drop leaves in the winter due to lower light conditions and cooler temperatures. When the weather warms up(above 50F), cut them back by 1/3 . Once they sprout in warmer temperatures, feed them with 1/2 strength 20-20-20 or a hibiscus fertizlier to get the plant started. Hope this helps. Kris

    Bougainvillea care. I live in San Diego, CA. My bourgainvillea is being eaten by something, perhaps called bougainvillea looper. What specifically is the best treatment?

    The bougainvillea looper often referred to as inchworm is a brown or green caterpillar 1″ long . It is hard to detect because it mimics a stem and feeds at night. The moth lays its eggs on the underside of the leaves. It is the caterpillar that eats its way from the tender shoots down to the foliage causing scalloped edging on the foliage. Other than deforming the plant it will not kill it. The safest way to treat it is with Bacillus thuringiensis (BT) sold as Dipel or neem. Both controls will kill the looper with out harming any beneficial insects. Spray in the evening when they are actively feeding.

    Hello,

    I live in Marseilles, France, and am going to plant some Bougainvilleas into the soil. Would it be OK if I use a trellis or pergola for support, are this plant wind-sustaining? We have strong winds pretty often.
    Thank you,Tanya

    Hi Tanya,
    Bougainvillea are a popular plant in southern France. A pergola or trellis will be a great support for the woody canes that can climb up to 40 feet. They should with stand windy conditions but if you want to make sure secure some of the canes to the pergola when they start to grow.

    Leaf spot disease
    I live in Scotland and I have my bougainvilla in the conservatory, I have noticed that there is small brown spots with a reddish brown colour circling the spots on the leaves I have been doing what the care instructions tell me, please help?

    It sounds like a leaf spot disease which is tan with reddish margins and caused by a fungus or bacteria. It’s difficult to say which one. High humidity, overhead watering are usually the culprit.
    Remove the infected leaves and give the plant more air circulation so that it can dry out. http://www.doacs.state.fl.us/pi/enpp/pathology/pathcirc/pp343.pdf

    I live in Athens Georgia and have just purchased 4 hanging boug. baskets. The temps are supposed to go down to 44 and 42 the next couple of nights. Should I bring the baskets into the garage or will they be OK in those temps? I don’t want them to lose their blooms – they are beautiful right now and we are having warms days.

    Don’t tempt fate. At 44F, bougainvillea will survive but the flowers may drop off. Store them in the garage until the weather warms up.

    I have a pink bougainvillea but i live in Glasgow, Scotland. the Weather is normally cold and wet. I do not have a garden but my kitchen gets allot of sunlight. It was fine for a week but the pink leaves are falling off. any ideas of what i should do??

    HI Claire
    I need a bit more info. Is this a new plant that you just recently purchased?

    Yes. only had it about 2 weeks now. its quite small but had a bunch of pink flowers at the top and the bottom. all of the bottom flowers have fallen off and a few of the top ones. i live in a flat so there is no option of me putting it outside.

    Hi again
    The problem is that bougainvillea needs lots of sun(6-8 hrs) and warmth to bloom and thrive. It was most likely grown in a perfect greenhouse environment and now is in a lower light and cooler climate. It is adjusting to this new environment by dropping its flowers. Frankly, it will be a challenge to it grow indoors as they thrive much better if allowed an outdoor summer vacation. Keep it in the sunniest window, let it dry out between waterings(don’t overwater) and fertilize once a month with a balanced fertilizer. I hope it proves me wrong and grows magnificently.

    Scale
    I have a bougainvillea that is a couple of months old, showing new growth, but with the new leaves have black spots (small black raised dots, looking like bugs), as well as beige colored flakes sprinkled all over the stamen and leaves???? What is it?

    Can you scrape off the “raised dots” if so, you may have scale. Black spots can also be a leaf spots.

    Yes, and they are definitely tiny bugs. When I scraped them, they came off easily and are dark green, but also there are light green ones, which I couldn’t detect until I scraped them off.

    It sounds like scale. The lighter ones are juvenile stage which are difficult to detect. You should also have some sticky residue on some of the leaves or stems. See scale for treatment suggestions.

    I have 2 Bougainvillea vines in red that are about 4 feet tall. I originally was going to train them to be on a trellis, but cannot do that. Can I train them to be bushes and use in the landscape that way? Thank you

    Yes, they can be trained to grow bushy. The best time for heavy pruning ( cutting off 3/4 of the plant) is late fall or early spring. You can trim it throughout the growing season especially after the blooming cycle.

    I live in Dallas and have a beautiful fuschia boug that I take in the garage every winter. It bounces back in the spring and looks great all summer. This spring it was magnificent until the first hot day in the low 90s. Knowing it needs to be a bit stressed, I was watering every 2 days and had given it 3-month food about a month ago. (It also sits in direct sun.) After the first hot day (when several of my petunias wilted and died), it dropped all of its flowers. It still has leaves. Will it bloom again? What can I do to prompt more blooming? Is this normal?

    Hi Melissa
    To much of a good thing can also be stressfull. Your bougainvillea couldn’t cope with a sudden heat and sun and dropped its flowers. Also keep in mind that stressing it is keeping it root-bound and letting the plant dry-out between watering. Too much water will encourage more foliage instead of flowers. It may stop blooming for a few weeks but should begin to rebloom on new growth.

    THRIPS
    I live in Mexico and have various different bougainvilleas. I have discovered that they are all infected by thrips, as are most other bougainvilleas in neighboring gardens. How can I get rid of them and will they kill the plants? Sheridan Sansegundo

    HI Sheridan
    Thrips will suck the juices out of flowers and new leaf shoots. They are attracted to blue flowers and can transmit viral disease. Other than disfiguring the plant it should not kill a healthy plant. To monitor for thrips, hang blue-colored sticky traps by the plant. Yellow traps will also work by are not as effective.
    A spray that contains spinosad (Conserve) is a biologically,safe organic insect killer which you can spray directly on the flowers and leaf buds. It works by contact and by injestion and will not harm most beneficial insects or predatory mites.
    A systemic such as Orthene will give you long term control. Orthene is not environmentally friendly since it will kill all insects even beneficial ones.Extreme caution should be used during application.

    I received a bougainvillea hanging basket for mothers day and it was beautiful then. But, it hasn’t had many new blooms. Just a bunch of long spindly branches with old spiky shoots on them. Do I cut the whole branch back, or just the spikes?

    Hi Natalie
    It may be that your bougainvillea basket is not getting enought sun or fertilizer to bloom. They are heavy feeders and can use 1/2 strength balanced fertilizer every two weeks. Keep the plant slightly on the dry side- the stress will encourage it to bloom. Since bougainvillea bloom on new growth, cut the spindly branches up to a 1/3 or pinch back the spiky shoots lightly to promote new growth and additional bloom. After pruning, it should rebloom within a few weeks.

    In the postings, it is suggested using 1/2 strength fertilizer to boost growth of the bracts/flowers on Bougainvillea. At one point, 10-10-10 was noted and at another 20-20-20 was noted. So, does this mean taking a 20-20-20 solution and dilute it by half according to the package directions? i.e., 1/2 t instead of 1 t to gallon of water? Thanks.

    Yes, a 20-20-20 formula is twice as potent as the 10-10-10.

    Yellow leaves
    I have 2 bougs vines on each post of my pergola, in late spring they were doing great beautiful dark green leaves and loads of fuschia blooms, now one of the vines is doing bad, it’s leaves are turning yellow and no blooms. I live in zone 9 and they get full sun. I water and feed both of them the same. I have loam soil over the clay. Why is one of them doing bad? Thank you

    Hi La Tanya
    Yellowing leaves can indicate too much water. My guess would be that since the soil is loam over clay there may be a drainage problem. When the roots grow and reach further down into the soil, they may be in the clay soil that has a tendency to retain water. It may be that one side of the pergola has more clay than the other. Try watering less and make sure your fertilizer includes micronutrients such as magnesium and iron which are common defieciencies that can also cause new growth yellow leaves. For older yellow leaves give the plant epsom salt 1-2tsp/gal of water.

    I received an old Bonsai Bougainvillea today and when it was unpacked, found only a few (under 5) leaves attached. The entire tree, save the 5 leaves is bare. It is mid-summer here in SW PA. I watered the plant and placed it in a moderately sunny location. What do I need to do to promote new leaves, if anything.

    Hi John
    Bougainvillea will drop its leaves in low light. The sunny location and moderate watering will encourage new growth. When you see new growth fertilize it every 10 days to two weeks with a hibiscus fertilizer or a balanced fertilizer (10-10-10) with micronutrients. Follow directions on the package.

    Hi Deb
    It needs full sun to bloom best. The best time to move this tropical plant is in the spring before new growth starts or in the fall when its done blooming or goes dormant. Take care when moving it, the delicate fibrous roots don’t like to be disturbed and are easily damaged.

    I brought two very small Bougainvillea plants back to Massachusetts with me, planted them in full sun, in a large pot, and gave them some plant food and a little manure. They have grown like crazy in two months, and are nearly ten times their original size with huge, lush, dark green leaves. The problem is that there is not a single fuschia flower on it. It’s growing so well, but why no flowers? Any help would be greatly appreciated.

    Your bougainvillea is soo happy with all those nutrients that it grows and grows but does not want to make flowers. Its possible that it has too much fertilizer and water. They also like to be pot-bound before blooming. To get them to bloom- keep them on the dry side , let it dry-out close to the point of wilting between water and don’t fertilize. Hopefully, it will stress them enough to bloom.

    Scale
    I live in San Diego CA and have 3 boug vines espaliered on a wall. They are 30 yrs. old. For the past 2 years the central plant has dropped its leaves, new growth appears, then drops while immature. The leaf surface appears ‘bumpy’. The adjacent plants are healthy and vigorous. We sprayed with Spinnosad. Deep watered. No joy. To break this cycle we recently cut the plant back to bare trunks. Any idea what is happening?

    Hi Lynne
    You might want to examine the “bumps” on the leaves closer. Can they be scraped off? If so, your bougainvillea may have scale which may need several treatments

    I live in Palm Springs, CA (desert) with no gardening experience. I just returned from a two week trip. Most of my boug’s new growth leaves have been munched. Also, there is some fine webbing on some leaves and there was a lot of black soot on the pavement below. I haven’t detected bougainvillea looper when I looked close, but that’s what it probably is. Can you confirm? I didn’t know if it was something else because of the webbing and all the black soot on the ground. Thanks.

    Hi Matthew
    It does sound like the bougainvillea looper. Look underneath the leaves. They feed at night and hide during the day camouflaging as stems. The black “soot” is looper excrement and webbing is when they pupate and turn into moths. BT works on young caterpillars and Spinosad is more effective on adult caterpillars.

    I live in southwest florida. When should I prune, fertilize and water the bougainvillea? Thank you.

    The best time to prune your bougainvillea is right after flowering or at the start of the rainy season. They can take light pruning all season long. Major hard pruning should be in the spring. You can feed it with a 1/2 strength ferilizer such as 20-20-20 or high bloom fertilizer like Hibiscus food every month if grown in a container or give it light feedings 3x are year. Careful not to overfertilize esp. Nitrogen or you won’t get flowers. Keep your plant slightly on the dry side to promote blooming. The soil should not be soogy and allowed to dry before watering again especially in winter.

    TRANSPLANTING BOUGAINVILLEA
    I need help!

    I recently replanted two bouganvillea’s from a pot into the ground in my Los Angeles garden. There were two plants in the same pot which I separated and planted in different spots. After a week in the ground neither are looking very happy and I’m worried I damaged the root ball’s when replanting them. I’m hoping there is something I can do to rescue these???? Any help would surely be appreciated – It is so sad seeing these once bountiful plants looking so droopy…. Thanks in advance.
    Charlie

    Hi Charlie
    Give them a little more time. Your bougainvilleas are going through transplant shock and need time to heal. Disturbing the roots and perhaps a different light exposure is enough to cause the plants to wilt. The damaged roots need to rebuild so that they can send up moisture to the leaves. Best thing you can do at this time is to give the plant a little shade and prune back the stems by at least 1/3 that way the roots will have less foliage to support. Once it stops sulking it should start to put on new growth.

    Hello,
    I live in Fort Lauderdale, FL and I have a beautiful Bougainvillea that I planted about one and a half years ago. It had blooms on it when I planted it. It has grown over eight feet high and vines over beautifully, lush and healthy. It has not bloomed since the initial flowers fell off. My neighbor has the same colored Bougainvillea and it blooms a lot. I know that they do not like much water, so the only water it gets is when it rains, which it does a lot during our rainy season (but still does not bloom during the dry season). I cannot understand why mine and my neighbor’s are both outside, get the same rain, but mine does not bloom. I love the color and planted it with love to bloom. Please help!

    HI Adina
    Perhaps your bougainvillea is getting too much love. They bloom better under stressfull conditions (dry). Wet conditions will stimulate lots of green growth and no flowers. It may be getting less sun than your neighbor’s bougainvillea . Your soil may be too rich with nutrients or not drain as well(holding moisture longer) as your neighbors. Too much fertilizer or nutrients will produce more green growth and no flowers. When fertilizing – use a high-bloom fertilizer (higher phosphorus). Bougainvillea bloom on new growth try cutting it back in the spring before new growth starts to stimulate blooming. If all fails ask your neighbor what she/he is doing.

    We have a villa in the Algarve, Portugal where there is a beautiful purple mature (at least 20 years old) bougainvillea.
    This year the leaves have developed a white sticky powder and many of the branches appear lifeless, it is a sorry sight.
    Has anyone come across this problem and is there a solution.

    Hi Dave
    It’s possible that your bougainvillea has powdery mildew that caused the white powder. In addition if you have clear sticky areas then check for insect infestation such as scale.

    Tree shape
    I live in Florida and have a beautiful bougainvillea that is planted in the ground ..it was so woody and too big so I had it pruned back to about 4 inches and its starting to get good growth but I would like to train it to be more tree like than bushy..please advise..thank you Sharon

    It is a slow process and may not be easy with an older well established plant. To train bougainvillea into a tree form, you will need to choose a healthy thick branch and elliminate all others. The roots will channel all nutirents to the main stem. Train(wire) the branch to grow up on a straight pole and trim away any new growth that may sprout on the main stem leaving only the top growth. You can also pinch the top growth to attain a bushier shape. You will have to cut away any additional sprouts that the plant will send out from the ground.

It gets full sun most of day and is on our drip system. The soil seems moist but not wet. What could be going wrong so fast? Thanks..Susan

    Hi Susan
    I suspect that the plant is being overwatered with your drip system. Let the plant dry out between waterings. Bougainvilleas prefer their soil on the dry side

    Boug fertilizer
    I bought my boug last spring and it only gave me a few blooms. Through the advise that I read here, I brought it in over the winter, leaves fell but surprised to see some blooms. I placed it by the door where it gets full sun. Can you recommend a good fertilizer brand to encourage more blooms. When is the best time to bring it out in the spring?

    Hi Laurin
    Wait till spring when night temperatures are 50’s to bring it outside or danger of frost is passed. Start fertilizing with a balanced 10-10-10 with micronutrients or a hibiscus fertilizer when new growth begins. You may also want to prune it to maintain a shapely plant.

    I have just planted two bougainvillea in large seperate pots on my roof terrace in Spain. Both are in full sun and I am keen to ensure that they grow well. I have read somewhere that boungainvillea like cold tea, is this true.

    I would like any tips you can supply. All my pots are on an automatic watering system, would you reccommend that I do not put these bougainvillea pots on the system and instead water them by hand

    Hi Jenny
    Watering bougainvillea with tea will not harm the plant. The acid in the tea will keep the ph low in the soil. This can also be done with coffee grounds. I balanced fertilizer will give the plant all the nutrients it requires. You can try them on the watering system as long as the soil is allowed to dry out between waterings. Since they grow in warm climates of low rainfall and hot sun, bougainvillea like it on the dry side with increased moisture during flowering. If you have soil that is too wet, you will have a problem getting them to bloom and developing root rot.

    Grow upwards on pergola
    I have a deep pink bougainvillea which we hoped would grow very quickly up the pergola on our terrace. While it is very healthy and flowers well and with many lateral branches , it is not growing up the pergola as intended. Any tips on how we may direct the branches upwards?

    Hi Srini
    Long bougainvillea stems have a tendency to gracefully cascade with the pull of gravity. You may have to gently coax the vine to climb up the pergola. Tie the vine to the pergola to encourage upward growth.Pinch the side branches but not the tip along the stem to encourage the tip to grow upward.

    Transplant shock
    I live in Arizona & I just planted 4 bougainvillea’s in my yard 2 weeks ago, they are showing new growth but some of the leaves are wrinkled & the flowers have yellow on the edges & look as if they are wrinkling up. At first they had yellow flower buds in them & whatever it is seems to be taking life from them. I am hoping they will survive. I water them every day & sometimes every other day. Help, what can I do? I dont want to lose them. Thankyou

    Hi Jackie
    Most likely your bougainvillea is suffering from transplant shock and needs time to adjust.The damaged root system has a difficult time moving water to other parts of the plant. Keep the plant stress free, make sure the soil is moist but not wet, provide a bit of shade until it recovers. You can try adding a root stimulant to help repair the roots.

    I have several bougainvilleas with leaves that have been chewed but I have not seen the culprits. I read about moths affecting them. Please advise.

    Hi Nick
    There is a bougainvillea looper a green or brown caterpillar that feed on the plants. The bougainvillea looper often referred to as inchworm is a brown or green caterpillar 1″ long is hard to detect because it mimics a stem and feeds at night. The moth lays its eggs on the underside of the leaves. It is the caterpillar that eats its way from the tender shoots down to the foliage causing scalloped edging on the foliage. Other than deforming the plant it will not kill it. The safest way to treat it is with Bacillus thuringiensis (BT) sold as Dipel or neem. Both controls will kill the looper with out harming any beneficial insects. Spray in the evening when they are actively feeding.

I scraped near the bottom on the trunk and saw green and there is kind of a yellowish / green in the middle of the branches when they are cut. I am hoping for the best I really love them. Right now they seem really dry and growth is very little to none.

    Your bougainvillea may be marginally hardy where you live and had some winter dieback. On the other hand , they do like warm weather and will not start growing until the soil warms up.

    I live in Singapore. I bought 2 pots of bougainvillea plants while they were in full bloom. I re-potted one after the existing flowers on it dropped. But while doing so I accidentally pulled the plant out from the soil which held its roots. The main roots were exposed. After replanting it in the new pot for more than 3 months now, it still does not flower while the other pot has not stopped flowering. I may have hurt the roots while re-potting. What must be done to remedy the situation?

    If the roots were damaged, then they need time to repair themselves before the plant even thinks about blooming. Bougainvillea blooms best when it is pot bound.

    Overwatered bougainvillea
    I have a young boug potted last year on my patio in So. California. I have a feeling I overwatered it, as there were mushrooms growing in a the periphery on the surface of the soil and yellow spores just under the surface and in the root holes of the pot. The plant is still growing very small leaves and flowering sparsely. Is it salvageable?? Thanks.

    Hi Samuels
    It sounds as if it is struggling. You need to replace the soil and check the plants fine roots at that time. There should be some cream colored fine roots. The soil should be porous and well drained. Use a good soilless mix. Avoid using a peat and perlite mix as it may compact and retain moisture. Make sure that the pot has drainage holes and do not let the plant sit in water or it will cause root rot.

    My aunt has a bouganvilia which is over a year old. The plant did not bloom at all this year, despite fertilising with Miracle Gro during spring and summer. It has sat outside on the deck basking in plenty of sunshine, so I can’t imagine what could be wrong! The plant is still healthy, with lots of green leaves, and my aunt plans to bring it in since temperatures tonight will drop to 0C. She lives in Nothern Canada, in the Muskoka region, and will definitely overwinter the pot indoors.
    Any comments on what can be done to ensure the fabulous pink blooms of last season?
    Thanks.

    Hi Ray,
    Here are some cultural suggestions that bougainvillea needs to bloom. It requires at least 6-8 hrs. of full sun. They respond to blooming when they are slightly stressed- crowded roots and the soil kept slightly dry. In addition, blooming occurs on new growth so a light pruning will stimulate new growth. Lightly fed your plant 2-3 times a year with a balanced fertilizer. In general, lack of flowering usually happens from not enough sun, too much water, too much nitrogen. There are also varieties of bougainvillea that bloom in the fall in response to short days

    Hi Zareen
    You can prune it in fall or early spring. Since you are taking it to the conservatory where it will get proper heat and light you can prune it now to stimulate new growth and (since they bloom on new growth) also flowering.

Then I give it a good drink. Should I give it some fertilizer?. I use a 15 15 15 formula. Thank You.

    Your bougainvillea is in a much lower light environment than it was outdoors therefore will normally drop leaves. Do not fertilize your plant during the winter, save it for early spring when it will start to grow again.

    We live in Seal Beach, CA and planted several bougainvilleas in a row along a wall about 2 1/2 years ago. Most of them became bare sticks within a month and have stayed that way. We’ve had a couple gardeners look at them and they say they are still alive and to wait while they establish their roots. Well, we’re about to give up. We thought these plants grew quickly and easily. They are in sun for about half the day and we are watering them with a drip irrigation system. They are in the ground in a space about 2 feeet deep between a wall and the tiled patio. We’d love some advice!

    Hi Jenny
    It sounds as if your bougainvillea are off to a slooow start and something is wrong. The location may be the problem. They need full sun – that is 6 hours and more. The irrigation system may keep the roots too wet causing root damage thereby slow growth. Bougainvillea grow best in porous, well drained soil that is on the dry side. After 2 1/2 years, I would plant them in a different location in the spring.

    Hi Linda
    Give them the scratch test. Scratch or scrape the stem and see if there is green underneath. If not, then the stem is dead. A dried up stem that easily breaks is also a clue that it is dead. Even if the stems are dried up and dead you may get new growth from the roots if the didn’t freeze.

    Hi Gary
    Bougainvillea need warm weather and warm soil to get growing. Bring the pots outdoors when you are sure night temperatures will be above 55F. Then it becomes a waiting game. The stems may be dead but the roots can send out new growth when they are ready. Once this happens, you will know what part of the plant died and then you can trim off the dead stems.

I would like to move them but am afraid of damaging the roots beyond repair. Any help would be appreciated.

    Hi Mark
    The best thing you can do is to dig around the pots so that you get the roots that are growing into the ground. Once you have your “clump” cut off the plastic pot and plant your bougainvillea immediately in a predug hole and water. You can also add a root starter into the water to stimulate new root growth.

A Barbara Karst bougainvillea, growing up a west facing stucco wall under an eave, seems to have died. I bought a new one yesterday and am considering using a pot in the same location, though the goal was to have the branches fill an iron trellis on the wall, so moving the pot, if we have another deep frost, will be difficult. We may rig up some sort of blanket system for Dec. nights. We could include an outdoor lightbulb for heat. Can you tell me which bougainvillea best endure frost?

    Hi jane
    Bougainvillea are slow to start in spring. They need warm soil before they think about waking up. The best way to see if it is alive is to scratch the bark on the stem and see if there is any green underneath. If not them there’s a good chance it did not survive. Although it may send new growth from the roots, so don’t give up too fast.

    Hi there!
    I live in Northern California, and recently fell in love with bougainvilleas. I now have 3 potted plants in full sun on my porch. The beautiful pink color they had when I first got them has not turned into a deep red. I LOVED the bright pink color, and would like to know if you have any suggestions on how to get that pink color back. I saw in one of your other comments you suggested Miracid. However, as a recent gardener, I’m not sure of how much to use, and if that is all that is needed to bring that pink color back to these wonderful plants. Can you offer any advice?

    Hi Nancye
    The change of flower color is affected by several factors: temperature, amount of light, quality of light, ph and micronutrients in the soil. Low temperatures, more light increase anthocyanin which is the red/purple pigment in plants. Conversely high temps and lower light decrease anthocyainin . Ph and fertilizer can also have an affect on the shade of red in certain cases. The more intense color is probably due to the amount of light your plant is getting. The bracts are lighter in lower light conditions. I have a flowering quince that is a deep coral color in the sun but when I took cuttings and brought it indoors the flowers were all light pink. You wouldn’t know it came from the same plant. I don’t know if the Miracid would have any affect on the color.

    Your varigated bougainvillea may be more sensitive to adverse soil conditions. By transplanting, the roots are damaged and are unable to provide enough water to the leaves causing them to wilt.They don’t like to have their roots disturbed. Keep the plant in a shaded area until it recovers and be careful that you don’t overwater the plant as they prefer to be on the dry side. In additon, do not fertilize it until it recovers and starts to put out new growth. Both overwatering and too much fertilizer can cause the leaves to curl.

    Mold on trellis?
    I have two twenty year old Bouganvilleas in San Jose, Ca. that are trained to climb up a garage wall. The leaves are fine but where the roots are coming out of the ground they are covered with a white powder. It even seems to be on the wooden trellis holding the plants up. Is this powdery mildew? I would expect it on leaves but not on the wood.

    Hi Claire
    Powdery mildew grows on plant material, you may have some kind of mold (fungus) growing on the trellis.

    In fort worth, texas: I bought 2 huge hot pink bougainvilleas that are about 6 ft. tall. I put one of them on the side of the house against our brick wall which faces southwest, and the other on the northeast side of the house. The one on the southwest receives sun from about 11am-sundown & northeast side receives full morning & afternoon sun. I’ve kept both in their original pot they were purchased in for fear of disturbing the root (& terrible, clay, rocky soil), so for the southwest side dug a hole in our bed and put it against the wall. The northeast one is potted inside another big pot. Right after purchasing, we had a week long rain with very high winds. The southwest facing one was VERY unhappy, as it gets hit with the south wind almost all day. Many leaves & flowers have fallen off, it’s very leggy looking, and has a few blooms on the top but yellow on the leaves. I’ve since moved it to the southeast, a bit more protected with full sun. The other one is just as I bought it, happy as a lark on the northeast corner. I’ve fertilized both with 20-20-20 (given by the store i bought it from). What to do??

    Hi Kristen
    You are right to move the plant to a more protected area. The bougainvillea is still adjusting to the new environment and is experiencing a type of transplant shock-too much sun, water and wind. Make sure it stays on the dry side and don’t fertilize until new growth starts to show.

    Hi. We live in Qatar, and I’ve overwatered my purple bougainvillea plant in a pot.
    The leaves are all dried up and still on the stem, but the plant looks dead.
    I’ve since moved the plant to a sheltered spot and stopped watering, safe for a very little bit (gauging by giving the dead one a quarter of what I give my other thriving plant)
    How do I know if it’s still alive? And if it is, what should I do? Thanks for any advice.

    Hi Jenny
    Water as you are for now keeping the plant slightly moist. If and when there is new growth, increase watering, fertilize (1/2 strength) and move the plant to a sunny spot. Trim any dead, dried stems.

    About 3 weeks ago, I moved a bougainvillea from a large plastic pot into a 3′ x 7” rectangular wooden planter. I definitely hurt the large root ball in order to fit it into the new narrower box. Within two days, all of the flowers and leaves shriveled up and began to drop. The grower told me to trim it back about 1/3 (it is growing up a trellis on my deck), including all the dead branches with the leaves and flowers. That was nearly two weeks ago, and the plant is showing no sign of regrowth. Should I water it more or less than normal? Should I fertilize at all? I live in LA, and the plant gets full sun (southern exposure). Thanks!

    Hi Scott
    Your bougainvillea still needs time to recover from transplanting. By trimming some of the plant will help reduce the amount of top growth needed to recover. Keep the soil moist not too wet or too dry. You can feed it with a root starter fertilizer only to stimulate new root growth. When you see new growth, then you can lightly feed the plant with a balanced fertilizer.

    Yellow spots on leaves
    I have three bougalvillea’s planted about 3 to 4 ft’ apart in my yard. They were all doing so well,but yesterday i saw that alot of leaves fell off one of the larger ones.It also had yellow spots.I watered them.Now this afternoon when i came home from work, I checked them and the smaller one has yellow spots now.The third one looks great and is a very full plant.Any suggestions on the reason for spots will be greatly appreciated. Also, should they have flowers right now.Because even though 4 out of the 6 plants I have all together look great and are bushy.They have a few to no flowers. Thanks. JO H. Ponchatoula,LA

    Hi Joe
    Yellow spots can be from overwatering. If on older leaves yellow spot can be due to a magnesium deficiency. Add epsom salt at 1-2 tsp/gal as a soil drench or foliar spray or make sure your fertilizer includes micronutrients.

    I live in Southern California, and have a 5-year-old bougainvillea in a large pot in the backyard. It is in full sun (temperatures get very hot here), and for the past few months it has been doing wonderfully–lots of deep pink blooms. Now, all of the sudden all of its flowers have turned yellow and fallen off. It’s leaves are still there, but they are sparse and small. I stopped watering because I thought that might be the problem, but its been 2-3 weeks and the plant only looks worse. I don’t want to kill it, but I just can’t figure out what went wrong. Please help! Thank you.

    Hi Emily
    It is possible that since the plant was overwatered that it has root damage (rot). Keep the plant on the dry side but not completely dry. The fibrous roots need time to recover. You can treat it with a broad spectrum fungicide to help control the problem. Make sure the soil drains well so the roots are not sitting in water.
    Has the bougainvillea been in the same soil/pot for the last 5 yrs.? If so you might consider repotting it in fresh soil that hasn’t been compacted over the years.

    Overwatering
    After reading these comments I fear I have overwatered my bouganvelia. I live in NE Florida. It is constantly wilted and I thought it needed water so I watered daily. Can I reverse the damage I have done?

    Hi Patricia
    Recovery depends on how much damage (root rot) the fine roots incurred. Bougainvillea prefer to be on the dry side with well drained soil. Move it to a semi-shaded area and let the soil dry slightly before watering again.

    Flowers turn brown and drop
    Hi, thanks for all you do on this site. I live in San Diego and planted my Boug about 4 or 5 years ago. It is crawling up our neighbors ugly shed just as I wanted it to do. I left it in the pot when I planted it and just cut the bottom of the pot open so the roots could grow down. I was afraid of disturbing the roots. It gets full sun all day. Problem is, it will bloom all over and then drop all it’s flowers and takes ages to re-flower. We haven’t over-watered but also have not fed it. Your suggestion? All the flowers just turn brown suddenly over the entire plant and drop. Oh, and the gardner also had trimmed the branches at the bottom of the plant end of July. Any help will be greatly appreciated. Thank you so so much.

    Hi marsha
    It may be a fungal or bacterial disease that is causing the “flowers” to turn brown and drop. Avoid spraying the flowers with water. High humidity and rainfall help the disease develop faster. Crowded vines will help spread the disease.
    If that’s not the case, another possiblility; is the plant is kept too dry? They should be watered less to encourage bloom but during bloom time bougainvilleas need more water.

    Hi Linda
    Yellow leaves is a response to some type of stress the plants are experiencing. It may be that they are getting too much water, not enough water, lack of nutrients or have an insect infestation. Mandevilla will naturally shed some of their older leaves.

    Wintering bougainvillea
    I live in the Sacramento area and last spring bought a beautiful boug. I learned the hard way that bougs do not like a lot of water. And I also learned, throuhg previous bougs,that they don’t like the cold Sacramento temps of winter (we can get to 32 degrees F.—even though I covered them). The one beautiful boug I have now (Sept) is in a pot—how do I help it survive to next spring?

    Hi JC
    There are several ways to winterover bougainvillea as a houseplant or dormant (see article above). You may get away with storing it in a garage during the coldest months of winter or just move it indoors when temperatures drop below 40F so that they won’t freeze.

    Bougainvillea looper, powdery mildew
    Hi,
    I have a boug in a corner with privacy fence to one side and house to the other. We are in Orlando and the plant gets about 6-7 hours direct sunlight per day. It appears to have grown, but is now seeming eaten, with leaves falling off and no growth. Additionally, there is now white spots on the leaves. What can we do? Thanks!

    Hi Meredith
    You need to find what is eating your plant, one insect that does chew on bougainvillea leaves is the bougainvillea looper often referred to as inchworm is a brown or green caterpillar 1″ long . It is hard to detect because it mimics a stem and feeds at night. The moth lays its eggs on the underside of the leaves. It is the caterpillar that eats its way from the tender shoots down to the foliage causing scalloped edging on the foliage. Other than deforming the plant it will not kill it. The safest way to treat it is with Bacillus thuringiensis (BT) sold as Dipel or neem. Both controls will kill the looper with out harming any beneficial insects. Spray in the evening when they are actively feeding. The white spots on the plant sound like powdery mildew.

    Hi Joy
    Bougainvillea are tropical plants hardy in zone 8-10. It will tolerate temperatures as cool as 30-40 degrees for a short time but will need protection during a cold spell. You can try to cover it with a shrub frost cover and mulch around the plant for added protection during the winter. If the winter is unusually cold, your bougainvillea may drop its leaves but should resprout in early spring.

    I have three bougainvillea plants that were planted in the ground last year. We are in central California, where temperatures are usually ok for bougainvillea, but we had a few frosts and the plants dropped all their leaves, the stems looked bad, and I thought they had died. With very little hope, I left them in the ground, and late in the spring, they came back, but never flowered this season. Last winter, I wrapped them in Christmas lights that went on at dusk and off at dawn (but not until after the first frost, which I thought had killed them); is this enough to keep them alive, or is there another method of protecting them from the occasional cool spell during the winter? Can they be wrapped, and with what and how? Thanks for any advice you can offer!

    Hi Brooke
    You can wrap your bougainvillea with burlap to protect it from winter winds and mulch around the plant to protect the roots. Also, there are shrub bags that you can buy at garden centers that will keep your plant snug during the cooler parts of winter.

    Hi Francesca
    You can hard prune your bougainvillea by 1/2 to 2/3. Prune in late fall to early spring before new growth starts. Best time is in the spring, so that you can cut off any winter damage, hopefully, you don’t get that in S. Ca. Keep in mind that a hard pruning will make the plants stop flowering and go to a vegetative growing phase and fill in. Wear heavy gloves when pruning, watch out for the thorns.

    Hi, I live in Hong Kong and I have been away on vacation for two weeks. I have two bougainvillea and unfortunately was not able to water them during this time. My older plant with pink flowers now looks as if it is in a terrible state. All the leaves have curled up and it has dropped a lot of its flowers, and the ones which have not dropped feel very dry and the colour has faded. What can I do to bring my beautiful plant back to life? I also have some indoor palms and one of them looks like it has almost collapsed; some of the leaves have gone very brown and its colour is not the bright green that it was when I bought it, it is much paler and more brown looking. I have also noticed that there are some small black insects crawling around near the root stems…

    I look forward to any advice you may be able to provide to help my poor plants.

    Hi Chloe
    If your bougainvillea didn’t completely dry out, eventhough it dropped its leaves and flowers, it may send out some new growth. They can tolerate some dry conditions. If just depends on how dried they were. Keep the soil slightly moist but be careful not to overcompensate and maintain it in wet soil. You palm plant may have fungus gnats which can occur if the soil is kept too wet but I don’t think they are the problem. If the soil is too wet, the roots can start to rot causing the leaves to turn brown. If you have dry indoor air, check for spider mites.

    Fertilizer
    Hello, I live in central Florida &, after receiving some obviously bad advice, didn’t protect my bougs (25 of them!) throughout the winter. Initially, I was convinced they were dead then noticed most are growing back from the root. I’ve cut them WAY back & given them all about 2T of Bougain fertilizer. Is there anything more I can do to help them? I’ve heard coffee grounds might be good but I’m afraid I’ll hurt them. Thanks in advance for your advice

    Hi Sally
    Sorry about the cold damage. Bougainvillea will drop its leaves even after 4 hours of below freezing temperatures. The bougain fertilizer(6-8-10) is great. It is balanced to provide the right amount of nitrogen and phosphorus along with micronutrients (iron) to encourage bloom. Follow label directions as to how often to feed the plants- usually once a month. Recycle your coffee grounds and add them to the soil, they will not hurt the plants. They add organic material into the soil as well as a some nutrients.

    Plant bougainvillea in landscape
    I just bought my first bougainvillea and have enough plant knowledge to be dangerous. Currently it is in a 2 gal. pot trained to a small trellis. I would like to replant it in the ground against my house and train it to a larger, fan type trellis. This spot is right behind a line of beautifully blooming azalea shrubs, which I do nothing to maintain, except trimming to keep in rectangle shape. I’ve been told that the lime in the oak trees around my yard takes care of it for me. Is this a good place to plant my young boug? If so, could you tell me how and when I should properly transplant it into the ground?
    Thank you for any help provided

    Hi Debbie
    Early spring is a great time to transplant your bougainvillea. Before transplanting make sure the soil is well-drained. If not work up the soil and add organic material or compost. Plant your bougainvillea in full sun. A protected area such as against the house is a good idea as this tropical plant may need some winter protection in case of a freeze. When planting, place it at the same soil level as it is growing in your container. Water in well.
    During the growing season, keep your bougainvillea on the dry side, soggy soil will encourage root rot. Once the plant is established and starts to show new growth, start monthly feedings with a balanced fertilizer(10-10-10)or one formulated for bougainvillea.
    Ps.When composted, Oak tree leaves make the soil more acidic not alkaline (lime) which is a good thing in your case.

    No blooms
    I have three bougainvillea plants in one pot which I have grown indoors in Billings Mt for 20 years and which always bloomed regularly. I have since moved to a ranch where my plants have lots of leaves, perhaps less sunlight, but no blossoms in over a year. They are in a 14 inch pot. ? need to repot, or prune back. Appreciate any suggestions.

    Hi Dale
    Here are some ideas why bougainvillea won;t bloom. They need at least 6-8 hrs. of full sun. They respond to blooming when they are slightly stressed- crowded roots and the soil kept slightly dry. You don’t need to repot unless the roots are growing out of the pot. In addition, blooming occurs on new growth so pruning will stimulate new growth and more bloom. In spring, start to lightly fed your plant 2-3 times a year with a balanced fertilizer. In general, lack of flowering usually happens from not enough sun, too much water or too much nitrogen.

    I live in Mississippi and planted my first boug last week. It is about 2 feet tall amd is on a small trellis. I planted it by my mailbox so it is in full sun from 11am until about 7pm. I fertilized it with fish emulsion and watered very well when I planted it. A few days after planting it got watered by a sprinkler while I was watering my grass. The temp here has been in 80 during the day. A lot of the flowers have fallen off and the leaves are droopy and yellowish. I’m scared to water it again cause I don’t want to overwater it. Is the flower drop and leaf wilting/yellowing due to transplant shock or a watering issue? Is watering it twice in one week too much?

    Hi Claire
    Probably both. You want to keep a newly planted bougainvillea slightly moist but not wet or you’ll get root rot. Put some mulch around the base of the plant to keep the soil evenly moist. Once it is established, keep it on the dry side so that it will bloom. You will have to check the soil for watering and make sure it drains well. The plant needs about 1 inch of water once a week.

I have kept it indoors throughout the winter, (I’m in Canada) in a spot where it gets constant light but only direct sunlight for a few hrs a day. I water only when it dries out as instructed. I suggest you STOP WATERING! They don’t like too much water. Now with the warmer weather approaching, repot in new soil and put it outside.

     Bougainvillea are tropical plants, hardy in zone 8-10. They can tolerate temperatures as cool as 30-40F degrees for a short time but will need protection in winter or will freeze and die. That is why it is grown in a container and brought indoors or stored dormant for the winter.

     Hi Glady
     Leaf drop is usually caused by some type of stress, overwatering, underwatering, low light, cold temp or insects. The roots may still be alive. Prune it by 1/3 and give it a light dose of fertilizer(10-10-10). If the roots are alive it should put on new growth in a month or so.

     I have planted eight bougainvillea “Taormina Glabra” plants that have taken well on a south facing enclosed wall. I am concerned about loosing them to frost this winter! I live in the Isle of Wight UK. I have put light felt blankets over them as a precaution can you tell me if this is correct and how should they be fitted over the plants. At the moment they are foxed to the wall and drapped over the plant.

     Hi Brian
     Bougainvillea will drop their leaves after a freeze. The important thing is to save the roots. Add a few inches of mulch around the base of the plant and a few more during mid-winter. I don’t know how cold your winters get but covering the plants during the coldest part of winter is a good idea. It sounds as if you have your winter protection well in place. Drapping the blanket over the plant and securing the bottom should work nicely during a cold spell. Don’t worry if your plant drops its leaves, it should send out new ones when the weather get warmer. Here’s is some more info.. http://hortchat.com/info/bougainvillea-winter-damage

     I have a Bougainvillea with multicolored foliage–green and white, pure white, and red and white. The red leaves are down to one or two on the entire plant. Is there anything I can do to encourage the return of the red color. Is it a product of acidity, a mineral that should be coming from a fertilizer or a combination of other things? I have started this plant from cuttings but it’s a little harder to start than other varities. Any help you can give will be greatly appreciated. David Cayton

     Hi David
     Not sure what affects the leaf coloration in your case. It may be a genetic thing, a cultivar that is not stable. Color change is also be influenced by soil acidity, nutrient deficiency, amount of sun exposure or temperatures.

     I have a large bougainvillea growing outside. It is too large for me to move. How can I protect it during the winter? Any advice will be appreciated.

     Hi Patricia
     Bougainvilleas are hardy in zone 9-11 sometimes zone 8. It will tolerate temperatures as cool as 30-40 degrees for a short period of time but will need protection. During a cold spell it will drop all its leaves or worse freeze and die. For more info on wintering bougainvillea see:http://hortchat.com/info/bougainvillea-winter-damage

     I’m so glad you asked this question Patricia. I have 2 very large bougainvillea growing in very large, heavy pots—there is no way I could move them. I pretty much set my mind to the fact that they are going to die this winter (as another one did that I had several years ago) and I will have to buy 2 more next spring. I live outside of Sacramento—it can get quite cold here in the winter (several/many days of frost). I covered my last bougainvillea, but must no have done it correctly—-it was deader than dead in the early spring. I hope someone has suggestions ~

     declining bougainvillea
     I live in Southern California (Santa Barbara) and I am having trouble with some bougainvillea. My house had a large bougainvillea trained to grow over a door opening. The plant must have been 25 years old or more. It gradually weakened, lost leaves,and was not vigorous. After several prunings and fertilizations, I took it out. About three years ago, I planted two bougainvillea from 5 gallon pots in the same spot. The plants have not died, but will not thrive. I amended the soil when planting, fertilize with cow manure, water frequently enough (I think), but the plants will not grow. Bougainvillea grow wild along the freeways here. I am a fairly decent amateur gardener and have no problem with anything else. The area gets full sun. I have read that bougainvillea do not have stringent soil requirements, but I can only think that it must be a soil problem since the older plant gradually declined. I see no evidence of bugs or disease–just plants that will not thrive in a setting where anything else seems to grow very well. Any ideas?

     Hi John
     Generally, when a plant dies in a certain location, it is not recommended to replant the same thing. Your bougainvillea may have died a slow death from poor soil conditions,disease, insect damage etc. It’s difficult to say. It may be that the soil was too wet or overfertilized? Poor growing conditions will eventually kill a plant. Since the new plants are slowly declining, I would move them to a new location and replace them.

     Hi
     Help !!!! I have a beautiful bougainvillea growing in the back but now all of a sudden some of the branches have lost their leaves and look like bare sticks. I noticed some flea type insects or fruit fly type insect. We have also had a fair bit of rain.
     I also live in the tropical area of Brisbane Australia.
     Do I need to use insecticide if so what?
     Thanks

     Hi,
     I bought the most beautiful brilliant bright fuschia pink bougainvillea a couple of years ago. It was like the miami pink or temple fire color and it is doing great. Massive and tons of blooms. The only problem is the blooms have changed color. They are now the dark fuschia pink color like the Barbara Karst color. What happened? Is there anything I can put in the soil to get that beautiful bright pink back? Thank you for your help!!

        As you noted, Bougainvillea is generally a above average hardy plant and does grow wild in many areas.
        I am not sure what else has developed there since your posting.
        Obviously you like to have the plant(s) to be around that door and that should be fine if all others are in order:
        – Has the water source changed?. have you ever tested the PH of your water?
        – Bougainvillea does best in the soil with PH of 6-6.5. You may want to check that out.
        – Once a Bougainvillea has been there for more than 20 years, then something drastic must have gradually changed to have killed it. Was it a quick decline (over a couple of months, or a slower gradual process)? Is there another plant/Tree nearby that had since grown and is limiting the Suns exposure here?
        – Any chance that perhaps some pets or animals have been using the area around the tree, specially in months leading to the decline of the plant?
        – Most probably the “Soil Amendment” that you have done is not done in a large enough volume to have helped if the Soil was the main or major reason, as the new ones are not doing much better.
        -To fertilize a Bougainvillea, you are best to start it (as directed ) with “Bougain 6-8-10 Plus Minors”. You could order that online through Home Depot. While bougainvillea is a heavy feeder it can mange with less than desired food but does not do good with too much fertilizer, later on as the plant is established(after 1.5-2 years) you may not have to rely on a specialty fertilizer, and do what you have been doing (cow manure, etc.).
        – I wonder if you had a chance or did take some cuttings from the old plant before it was all thrown away, to use and propagate (grow some new plants from it). It is not very hard to have that done, just check online.
        Good luck, and perhaps you could let me see some pictures of the large old one if you have any.
        Steve

     I live in Hawaii. I bought three bougainvillea a white, a fuschia and an orange. I put them in the same pot. Had them on the porch and they lost their flowers. Put them in the sun and the flowers came back but the white ones are now pink. What happened and what can I do?

     I live in southwest Utah and so miss my southern California bougainvillea plants. I decided to plant one in a clay pot 2 years ago and move the plant into my garage during our cold winter. The past couple of years, the plant has done very well and blooms beautifully. I moved the plant out of my garage about a month ago and it is growing some leaves but they are lighter yellow/green and you can see the veins. I read that hibiscus food is good for bougs and I mixed some into the soil but the leaves still don’t look vibrant. Just wondering what it needs…thank you so much! Martha

     Hi Martha
     It will take some time for the fertilizer to take effect. Make sure it also contains micronutrients. Bougainvillea are heavy feeders so continue to feed them every 2 weeks.

     Is there any hope for a twenty year old bougainvilla which was recently moved from a condo to a retirement home. Blossoms dropped off, then leaves so all that is left is an umbrella of branches.
     Senior is watering it to try to bring it back. She is heartbroken. What shall I tell her to do?
     Thanks,
     Penny corbin

     Check the stems, if they are brittle and snap then they are dead.

     I purchased a bougainvillea and half of it seemed to die. The leaves turned brown and I thought I should prune them. When I cut one of the stems, the inside of the stem was green as if it were still alive. So now I have a plant where half has green leaves and the other half has brown leaves and I have no idea what to do. Help please.

     Thanks,
     Julie

        Left my bougainvillea outside beginning in mid-December and there have been multiple freezes and the soil dried out. Cut back the three potted, pot bound bougainvillea by half today, Feb 12, and am soaking the entire pot today only. All the stems seem flexible and green inside. The bougainvillea will now remain in my sunroom going forward…”when can I expect to see leaves?
