Gardenia care

The glossy dark green leaves and fragrant milky white flowers of the gardenia plant make it an irresistible plant to grow. Usually sold in bloom or bud, the intoxicating fragrance entices us to make it a must have plant but gardenia can be finicky and a challenge to grow in indoors. In fact, some treat it as a disposable plant and discard it after blooming.

gardenia flower

Gardenia (Cape jasmine) requires loose well-drained, acidic (ph4.5-6.2) soil, bright indoor sun 6-8 hrs and dappled shade (morning sun) when outdoors in the summer. It prefers high humidity and moist but not soggy soil. Feed it with a 1/2 strength acid fertilizer every 2-4 weeks from March-October.
For winter care: Provide a cool bright location, humidity and keep away from heating vents. Do not fertilize and water less by allowing the top 1-2 inches to dry before watering again.

Blooming: Gardenias require an even temperature of 62-63 F and high humidity during bud formation. To increase humidity place plant in a water pebble tray or close to a humidifier. When the buds are formed, provide consistent cool nights (58-60F) and warm days (70-75F). A 10-15 degree temperature differential is needed to keep the buds from dropping off (bud blast). Opened flowers should last 3-8 days and bruise easily when touched.

Prune after the blooming cycle has ended, or when the plant is actively growing and needs a trim. Don’t prune during winter.
Propagation: Take 3-4 inch semi-woody tip cutting from a non-flowering shoot in early spring. Remove lower leaves, dip in rooting hormone and insert cutting in moist peat, vermiculite mix. It should root in 4-6 weeks.

Troubleshooting
Gardenias attract a number of insects: aphids, mealy bugs, scale, red spider mites and thrips. They are also susceptible to root rot, bud drop and yellow leaves.

In the south and west coastal areas (zone 7b), semi-tropical gardenias are grown outdoors as evergreen shrubs. Varieties can differ in size, growth habit and blooming season. ‘Mystery’ a California favorite gets up to 8′ tall and produces large double flowers.

    Blooming requirements
    HI-JUST FOUND YOUR SITE AND LOVE IT. I HAVE A GARDENIA PLANT IN FLORIDA, BUT IT ISN’T BLOOMING, ALTHOUGH IT IS LUSH GREEN AND HEALTHY. MY MOM HAS THE SAME PROBLEM WITH HERS IN MASSACHUSETTS. WHAT CAN WE DO TO PROMOTE BLOOMING IN OUR OTHERWISE HEALTHY LOOKING PLANTS?

    Gardenia usually bloom once a year in the spring to summer. They need several conditions to set flower buds. Full sun 4-6 hrs , high humidity, cool night (58-60) and warm days (70-75). Flower buds form at a temperatures of 62-63 degreesF at which time the plant should have high humidity and even moisture. If the soil is allowed to dry out or is too wet, it will drop its buds. Fluctuation in temperatures such as too warm, cold drafts will also cause bud drop. They are a bit fussy. Feed the plant with an acid fertilizer (Miracid) from March to Oct. when the plant is actively growing. If outdoors during the summer keep it in partial shade. Prune the plant after blooming (spring) later pruning can eliminate next year’s flowers. The Florida climate should be great for your gardenia whereas Mass will require a little more effort to maintain the humidity it requires.

      Cut it back during the cool season and begin to feed it with a pinch of Muracid to a gallon of water every week. Do this for 4 months then do not feed it again for 8 months-just water. During feeding time it will set bud and become stronger. During the non feeding time it will rest. Gardenias need to rest to stay healthy and produce blooms.

    I have a question not a comment. I planted 3 gardenia bushes around my bay window last yr. and I think they are almost dead due to the extremely cold weather we had this winter. Is there a way I can save my Gardenia’s? I haven’t even seen them bloom.

    Wait to see how much cold damage you actually have. If you have dried up branches that look like there is no sign of life prune those and check for new growth as the weather gets warmer.They do like bright, warm and humid conditions with well drained, acid soil. If and when there are signs of life (new leaves) water and fertilize (muracid) in the spring to encourage growth. Gardenias are frost tender and depending on the variety hardy in zones 9-11.

  • Rita S

    I have several gardenias which have lost their vivid greeness. I purchased granular Ironite, but the bag only tells me how many pounds to apply to 1000 sq. ft. I do not want to apply to a large area, only to the plants which are yellowing. How much can I safely apply to individual shrubs of approx. 3′? I live in Texas, zone 8. Thank you.

    Ironite site recommends 1/2lb. application for a 2 ft. shrub. and one cup = 3/4 lb ironite. So here comes the math. 1/2 lb = 2/3 cup. That rate should be safe to apply around your shrubs.

  • christina

    I live in Greece and have just bought my first gardenia. How often am i suppose to water it and should i give fertilizer now?

    If the plant is indoors in a container, keep your gardenia slightly moist but not wet(don’t let it stand in water) and don’t let it wilt. You may have to check every day for watering, especially when the weather is hot. Water when the top inch of soil is dry. You may have to water less often in the cooler winter months. Also provide lots of humidity. Feed it with a balanced acid fertilizer(Muracid) once a month from March to October when the plant is actively growing. Follow manufacturer’s directions.

    Black Leaves and stems

    HI I HAVE A GARDENIA TREE IN FL LOOKED GREAT FLOWERED IN MAY -JUNE SINCE THEN THE LEAVES AND STEMS HAVE TURNED BLACK . CAN YOU HELP THANKS

    It is possible that your gardenia has sooty mold-a black thin layer of fungus that covers the leaves and blocks sunlight. Sooty mold feeds on honeydew which is a byproduct(excrement) of mealy bug aphids, whitefly or scale. Check your plant for infestation and treat accordingly. Each insect has a different course of treatment.

    YELLOW LEAVES

    I have a problem with Yellow leaves. What should i do to help the plant?

    Yellowing leaves on your gardenia can be a sign of overwatering, underwatering, too high ph (above 6.5) or iron deficiency. Iron chlorosis (interveinal lightening of leaves) can be caused by a high ph level. Feed the plant with 1/2 strength acid fertilizer or add chelated iron to the soil and spray on the leaves. You can also use tea water once a month to maintain low ph levels (acid soil).

    I have a formal water fountain garden with about 18 white gem gardenias and 18 english boxwoods which were planted in June of this year. The gardenias are very full with lush green foliage and bloomed all summer. At this time the outer leaves are still growing and healthy green however deep in the bushes there are yellowing leaves but they are not falling off. Any suggestion of the problem or remedy or is this normal?

    Hi Janice
    Some yellowing leaves can be normal if they are lower, older leaves or leaves toward the inside of the plant. If new leaves are yellowing on your gardenia, then there could be a nutrient deficiency (chlorosis). Also check closely for insect infestation such as scale & spider mites

  • CRAIG

    SCALE

    my plant leaves are shiny and wet with a sticky residue plant seems healthy and i cannot see alot of insect . ihave had mealy bug on my OLEANDER and have treated sucessfuly with malathion .should i use something different on my GARDENIA

    If you have mealy bug you would see it. Another insect that attacks gardenia and produces a sticky residue is scale which may not be easily detected. Look closely at the stems and undersides of leaves for bumps that can be scraped off with your fingers. A magnifying glass really helps. They leave behind a clear sticky residue on the leaf surface. The treatment would depend on where your plant is growing (indoors or outside). You can use malathion to treat for scale, if it is listed on the label. It will kill the insects in the crawler stage but not in the shell stage. You may need several applications. Don’t spray indoors and use precautions when spraying. Don’t use insecticidal soap on gardenia as they have a tendency to be sensitive to soap sprays causing phytotoxicity(yellow/brown spotting and burned tips.
    UF IFAS ext.serv. An ultra fine horticultural oil will also work on scale.

    Repot gardenia

    i have had a indoor gardenia now for 2 years and am not sure when re potting is required the plant is about a foot tall and very healthy please advise

    Repot your gardenia when the roots have filled the pot. You will see roots on the soil surface as well as coming out of the bottom drainage hole. They actually bloom better when slightly pot-bound. To allow for new vigorous growth, repot into a container 1 inch larger in the spring. It’s probably ready for the next size pot.

    DRYING AND CURLLING LEAVES

    A friend gave me a transplanted indoor gardenia plant with what looks like two plants in the one pot. It has been healthy looking for the past 4 months but recently one of the plant’s leaves have started drying and curling. Could one of the plants be root bound and should I pull it and try to replant it separately?

    The drying and curling of the leaves can be the result of stress on the roots caused by uneven watering or low humidity. Gardenias don’t like to have their roots disturbed. Separating the two plants would cause a lot of trauma to the already taxed root system, therefore I would not recommend dividing it. If you feel the plant is root bound, where roots appear above the soil and come out of the bottom drain hole ,then repot it into a 1-2″ larger container before it begins to put on new spring growth. Gardenias flower best when they are slightly pot bound. Trim the dried stems but don’t separate the plant.

    Leaf drop
    I have a gardenia that was given to me, it was doing not so well because I was having a hard time watering it regularly. So once I started doing that, it leafed up pretty good and got really green. I didn’t change the watering cycle, but for some reason all the leaves wilted and started to curl, and then….. when I went to touch the leaf, it fell off! All the leaves fell off except for some new growth at the end. I thought it might be the pot, so I recently repotted it – it’s doing a bit better, but there are still no leaves on the branches, just the new growth at the ends. More new growth has started to sprout up at the bottom – but what I am wondering is should I prune off the branches that have no leaves on them? Even if there is new growth at the ends? It just looks so naked with no leaves! It hasn’t bloomed at all since I got it for christmas. Help?

    Uneven moisture and low humidity will cause gardenia to drop their leaves and buds. Prune off any dead branches or ones that have no leaves on them. Since you have new growth coming from the base of the plant, also cut back the “naked” stems which will stimulate side shoots and produce a fuller looking plant. Provide bright filtered light, uniform moisture and humidity (place it on a pebble tray) and fertilize with 1/2 strength acid fertilizer(every 2 wks March-Sept) to get it going.

    Yellow buds
    I HAVE A GARDENIA TREE FOR ABOUT A MONTH, FULL, OF BUDS. AT FIRST THE FLOWERS WERE BEAUTIFUL AND NOW THEY ARE NOT OPENING. THE BUDS ARE YELLOW AND NOT OPENING, IT’S OUTDOORS AND GETS THE MORNING SUN. WHAT I’M I DOING WRONG…… PLEASE HELP. IT’S MY FARVOTE FLOWER, AND I LOVE TO HAVE THEM ALL OVER THE HOUSE THANK YOU

    Gardenias are very temperamental when in bloom, they will drop their buds or not open even when you look at them the wrong way. A change in location such as moving the plant, any temperature fluctuations cold and hot, low humidity, over and under watering (need even moisture when in bloom)and not enough light can all cause the flowers to abort or stop opening.

    Spider mites

    I have an indoor gardenia. It has new leaves and buds forming. But old leaves are turning yellow and falling off. Also there’s some tiny insects which are forming a web (like spiders). How do I get rid of them? I’m in NJ area. Thanks

    Gardenias are susceptible to spider mites which sounds like what you describe. The yellowing leaves can also be caused by lack of nutrients as well as old age. Spring is a good time to start feeding your plant with an “acid” fertilizer(Miracid). Follow manufacturers directions. Additional tea water every 2 wks will help keep the soil acid.

    Michelle ( Shellny2@hotmail.com / ) (IP: 24.45.47.178 )
    After seeing much of the same complaints I have about my gardenia plant, i checked under the leaves and found tiny dark specs that when touched came off and looked brownish red on my hand, almost like I smeared a bug. What is this?

    Hi Michelle,
    It sounds like spider mites. Wash the plant with water to remove the insect. Increased summer humidity will help keep it under control.

    Sara ( ego.sara@yahoo.com / ) (IP: 154.20.5.157 )
    Thank you for your response. I have not found any sticky substance however I did find tiny tiny traces of web. Perhaps spider mites? All the leaves look really dirty which appears to be consistent with spider mites. Would you have any suggestions on how to control them. Thank you

    Hi Sara
    Spider mites will attack gardenias when indoors. First thing-isolate the plant from all others and go to spider mites for more treatment tips. Note that gardenias are sensitive to inseticidal soap so you will have to use an alternative treatment such as a miticide.

  • Beth

    I live in Mississippi where for the past 2 weeks it has been in the mid 70’s to lower 80’s. Today I got my yard landscaped and planted some dwarf gardenia’s. I just saw on the weather that we are under a freeze warning tonight. It looks like it might not get down all the way to 32 but really close. Should I cover the gardenia’s?

    Yes, they will need protection from the cold. Cover them with a cloth, blanket but do not use plastic as that traps the cold and does more harm than good.

    BUD DROP

    how do i maintain the temperature differential required for the succeessful blooming of my gardenia indoors? it keeps getting buds which fall off, and it’s leaves aren’t lush green anymore. it had some tiny grey bugs on it which i’d been trying to control with some castille soap in water sprayed on it but it seems that the plant might be sensitive to it?
    thanks

    Gardenias are very difficult to keep indoors. The temperature differential is needed to get the plant to set buds-that’s why they are grown in a greenhouse where the temperature can be controlled. Usually, temperatures will drop enough at night and warm up during the day to keep the buds. They are temperamental and susceptible to many insects. I’m not sure what the grey bugs are-could be aphid or spider mites. I have read that the use of insecticidal soap can cause sensitivity to gardenia plants. Look into pyrethrin sprays labeled for gardenia. Your plant is showing signs of stress and will drop its buds any time there is a change in environment, high temp, low humidity,hot or cold drafts and to much or not enough water. Be careful not to overwater it or let it dry out -keep the soil evenly moist.

  • NIKKI

    Hi,
    I got this beautiful indoor Gardenia tree (not a plant) as a gift about a month ago. When I first got it, it had several flowers on it and looked pretty healthy…Now I’m seeing holes on even new leaves and the buds are falling. I have been watering it regularly and it’s in front of a window that gets full sunlight in the morning. I’m not experienced in growing plants so I have no idea what could be the problem. Anything that you can suggest will be greatly appreciated.
    Thanks

    Hi Nikki
    This is a good question since most of the “favorite” insects that attack gardenia are not chewing insects that make holes. It may be an insect that came with your plant, has regenerated and is thriving. Look for insects under the leaves and along the stem as well as in the soil. Once you find out what it is then you will know how to effectively treat it. I would also call the supplier of your gardenia tree and complain.

  • Gwen

    Hi,

    I have a beautiful gardenia bush that is taking over the space where I have it planted. When would be the best time to transplant the bush to another area. I am in Houston

    Hi Gwen
    Best time to transplant a gardenia is in the early spring late Feb.-March.

    Leaf drop
    My green-thumbed mother has successfully nursed many gardenias through moving and other stressful times. Just recently her perfectly healthy and blooming (indoor) gardenia dropped all of its leaves – practically overnight. She had done nothing differently from any other time. Do you have any idea what would cause this to happen, and what she should do now? Thank you.

    Leaf drop symptoms are similar to bud drop. The plant may be lacking nutrients, enough humidity or the soil was allowed to dry out. Gardenia will also drop their leaves as a response to insect infestation. Check for spider mites or scale.

    BUD DROP

    I live in Albuquerque NM and bought to gardenia tree/shrubs from Costco and planted in pots on the east side of patio. They were blooming at first but now the leaves are yellowing, falling off and the buds are not opening. I see the posts regarding the humidity which we don’t have a lot of here. Am i fighting a losing battle trying to grow these in this climate?

    Hi Francine
    It is a tough plant to grow in a drier climate. Not only does it need humidity, but some of the leaf & bud drop can be due to fluctuating temperatures and change in environment. Anytime the plant is stressed, it will respond by dropping its buds and leaves. Keep your plant evenly moist and fertilize it with half strength acid fertilizer 2-3 weeks after the plant is done blooming. You can spray mist the plant to increase the humidity.

  • Leah Jean

    I live in Boise Idaho and just bought a gardenia bush for a gift and thought that I would look up info about gardenia’s care to print out an article to give with the plant. As I am looking into gardenia’s it seems that it is a very troublesome plant. Is this the case or is it like the news where we are only hearing the bad news and not very many good stories. Will this plant grow in our dry and hot conditions outdoors, or should it be a potted deck plant to be taken in for our cold winters? What do you recommend to have a healthy plant here in Boise, Idaho? Thank you for your time!

    HI Leah
    I recommend a greenhouse.lol I love them but there is a reason why they have that reputation. The intoxicating smell may lure you to buy one but it is finicky and difficult to maintain for an extended period of time. Gardenia is a semi-tropical plant and does need even moisture and humidity as well as acid-soil. The hardiest gardenia can grow in zone 7 and up, Boise, Id is in zone 5b-6b, therefore you would have to grow it as a potted plant and bring it indoors for the winter.

  • DIANA N

    I AM CONFUSED ABOUT 6-8 HOURS OF SUN REQUIRED. I HAVE MINE UNDER A LATTICE PATIO COVER ON THE EAST SIDE. IT IS IN A LARGE POT. PH IS 5.0 IT NEEDS TO GET OVER THE IRON DEFICIENCY. SHOULD I MOVE IT TO FULL SUN? IT HAS BLOOMS, BUT LEAVES ARE LITE GREEN W/ DARKER VEINS. I SPRAYED IT THIS AM. W/ NEEM FOR SCALE ON LEAVES.

    Hi Diana
    Gardenia needs 6-8 hrs. of full sun when grown indoors. Outdoors, they prefer partial shade,AM sun, especially in the summer. The east patio exposure is great, I wouldn’t move it. Keep feeding it an acid fertilizer to help with the chlorosis (iron deficiency). Good luck with the scale.

  • Ginger

    I just recieved a gardenia tree , at my husbands funeral. I would love to keep this tree alive, in memory of him. It is in a pot right now. I live in Northern Georgia. Can the tree be planted in the ground ? Does it need to be brought inside during winter months ? Or would it be better to just repot it and keep it in a pot and take it out on the porch during the summer, so to bring it back inside during cold months. If I plant it in the ground, will it need a partial shade or full sun ?

    HI Ginger
    Sorry for your loss.
    Hardiness depends on the type of gardenia. Most are hardy in zones 9-11 and some of the cooler varieties are good in zone 8. You are in zone 8a which would make it marginally hardy in your area. Check the neighborhood to see if anyone is growing gardenia outdoors. They can toerate below freezing for only a short time. Plant it outdoors in well-drained, fertile soil in partial shade,with AM sun, especially in the summer. To be on the safe side, bring it indoors for the winter or keep in an enclosed porch.

  • Ina

    I had a gardenia that was doing pretty well inside and left a friend responsibility for watering it in my absence, for about 2 weeks. He says he did so, but on my return the tree was completely bLack, all branches were dry and dead. I pruned all the branches off leaving only the stem of the plant and am watering when the top soil is dry and have left it where it will only get sun in the morning. (I am in New York.) However after a week I can’t see any improvement, I am very worried that the entire plant is dead. The stem is blackish brown in colour and has light brown flaking. What do you recommend? I love this plant so dearly!

    Hi Ina
    Sorry to hear about your gardenia. It sounds as if it is beyond saving. Keep watering when the soil dries and if there is any life, it should send out some new leaves. Even then it will be a struggle, the plant would have to do a lot of growing to survive the upcoming winter season.

  • Ruth Wilson

    I’ve had a gardenia bush for about 15 years that is about 6-7 feet tall. It produces a lot of flowers each spring, but stopped having a scent. What does it need?
    Thanks,
    Ruth

    Hi Ruth
    A recent study at the U. of Virginia has discovered that pollution (burning of fossil fuels such as gas and coal) can have an affect the the loss of fragrance on a plant. The scent molecules bond to ozone and nitrate radicals that change the fragrance of flowers. http://www.independent.co.uk/environment/nature/why-flowers-have-lost-their-scent-812168.html

  • Darlene

    I have an indoor gardenia that I have repotted 4 times. I repotted because the plant was root bound. Each time after repotting blooms reappeared. The gardenia is in a pot that weighs about 100 lbs and again and looks like it needs repotted although I can’t go any larger (pot). My question is: Is there a way to “split” the plant without harming it. I live in Pennsylvania so putting it outdoors is not a good idea. I don’t want to lose the plant.

    Hi Darlene
    Dividing it is usually not recommended since they don’t like to have their roots disturbed and may not survive transplant shock. It would cause more harm than good. If you want to try, do it in the spring before new growth begins or after it is done blooming. Another way is to top dress your root bound gardenia in the spring. Remove or scrape away the top 1-2 inches of potting soil and then replace it with fresh potting soil that includes a slow-release fertilizer. Gardenia bloom best when they are a little pot bound.

    APHIDS

    Hello, I have an indoor Gardenia tree in Vancouver Canada. I bought it 3 months ago and it has done wonderfully up until now. My Gardenia is wilting and leaves are yellow but the flowers are also covered with white flakes. What are these white flakes?

    Hi Sara
    Is there any sticky substance on the surface of some of the leaves? Aphids may be the problem. They leave white skins on the plant after they molt.

    WINTER CARE

    Hi I live in North East CT I have an outdoor Gardenia tree that I bought in the beginning of the summer and it has been doing very well. I have been getting beautiful flowers but I have to bring it in soon, the nights have been getting colder. What does the temp have to be when its time to bring it in? And how do I winterize it? Do i need to change the soil completely? I dont want to loose it over the winter HELP :)

    HI Missy
    The article above on Gardenia will give you some tips on winter care. Bring your plant indoors when temperatures get below 50F. No need to repot or change the soil. They really don’t like their roots disturbed. You can repot after it is done blooming .Be sure to give it lots of humidity during the winter. Good luck

  • Tina

    I have just purchased 5 medium sized Gardenia Bushes to place in my front landscape beds throughout yesterday and today. I live in the Upstate of South Carolina, so I do live in a hardier zone for Gardenia growth. My worry is that I have placed them in a location that gets full sun during the hottest parts of the day. I am not so worried about it during this lovely fall weather, but I fear for next summer. Will they completely die off next year? This summer we ahd several 90+ degree days. I think my best bet would have been to do a bit more research before snagging them up at the nursery. I really don’t have any other area to plant them, as Azaleas are filling up the side of my house. Any tips/ideas as to the best care for them?

    HI Tina
    Gardenia can tolerate full sun, but as you mentioned it may be a problem in the hottest time of the summer. The best you can do is wait and see. The fall weather will help establish the plants. Mulch the plants with 2-3 ” of wood chips to keep the roots moist and cool. Be sure to fertilize with Azalea food once a month during the growing season and make sure it gets enough water during the hot season. A tree to provide some dappled summer shade would be nice. Good luck with your gardenia. Hope they grow well.

  • Mary Williams

    I live in central Connecticut. This past May I bought a corsage gardenia “tree” (about 4 feet tall. When I began to have bud drop and yellowing leaves drop, I fed it a liquid chelated iron mixture about mid August. It responded beautifully and has lots of buds once again. However, the leaves have begun to yellow again and now I’m afraid I will lose the buds. How often can I feed it with the chelated iron? It was on my deck until last week when I brought it indoors. It has plenty of light and I’ve fed it with miracid twice in the past month. It’s my absolute favorite flower and I’d hate to lose it. Any help would be greatly appreciated.

    Hi Mary
    You can feed chelated iron 2-3 times a year. One of the problems may be cold temperature. Gardenias need a temperature of 62-63F when buds are forming or the buds will drop. If the temperatures goes below 55F the plant is unable to use iron and the leaves become chlorotic (yellow). Make sure it is in a warm place with high humidity and then apply the iron. Also check for insects-they can also cause yellowing leaves.

  • Cathie

    I just purchased a gardenia veitchii yesterday, an impulse buy. I know nothing about growing gardenias. The only thing I’ve grown is roses. This gardenia is going in a pot, how big a pot does it need? I have one that is about a 10 gal that I was thinking of putting it in, but would that be to big to start? It’s probably a little less than 12″ tall and wide right now. Also how deep does it need to be planted? Does it need anything other than potting soil, I use moisture control miracle gro. I do have a soilless rose planting mix that has a lot of different compost type things in it (composted bat guano, chicken manure, alfalfa meal, worm casings and lots of other stuff too, organics), would it hurt it to add some of that in? I live in the Bay Area of CA and the temp here is fairly cool about this time of year. It averages highs in the mid 60’s lows in the mid 40’s. Is this temp okay for it to be outside now? It does get hot in the summer for highs, 90-100’s. Will it do okay in morning shade and direct afternoon sun? It can be moved to get more shade if needed, especially in the summer months. Can it be pruned down to keep it fairly small if needed or will that hurt it? Thanks for any info you can give!

    Hi Cathie
    I would not transplant the gardenina at this time as they don’t like their roots to be disturbed especially when they are starting to form flower buds. Gardenia set flower buds in the fall. Repot after the plant is done blooming and plant it at the same soil level that it was growing. You can mix in some compost to your soil mix, just make sure it drains well. Keep in mind that when you use moisture control soil the plant will need less watering. Afternoon sun in summer may be too much, I would move it to a shadier spot at that time. Pruning should also be done after bloom. Gardenia is hardy in zone 8-11

  • Haley

    I live in Houston, Texas. I have Gardenia planted in front of my house. They have lots of flowers, but the leaves look like the have a layer of black powder on it. From earlier comment, I think it might be aphids. What can I use to treat aphids?

    Hi Haley
    Gardenia in bloom are difficult to treat as any spray may also damage the flowers. You can try yellow sticky traps to attract the aphids or handpick by squeezing them between your fingers to reduce the population. A hard spray of water can knock them down. Neem and a pyrethrum/alcohol spray are effective. Look into pyrethrin sprays labeled for gardenia. Insecticidal soap can cause sensitivity to gardenia plants so that’s not recommended.

  • Kathryn

    Enjoyed reading all the questions and comments! I have an outside gardenia that lives in a pot facing the east morning sun. When temps get below freezing, I move it to the garage until the temps come back up. Here it is late November, temps in 40’s & 50’s day, low 30’s and 20’s nights – my gardenia is full of huge buds! Why?

    Hi Kathryn
    Congratulations!! Apparently, your hardy gardenia liked the humidity and cooler temperatures( 10-15 degree temperature differential) it received to set bud.

  • Sharon

    I live in California, my gardenia plant is in a pot out on my porch, the leaves are beautifully green, however they are droopy. I have watered it, but it just stays droopy, no flowers yet. What is wrong?
    Thanks

    Hi Sharon
    The wilting problems may be caused by either too much water or not enough water. If you soil is wet and the gardenia is still wilted, then it may be overwatered which can cause root rot. Be sure the pot drains well and the plant is not standing in water. If it is a case of underwatering, the plant should perk up within a few hours after watering.

    Transplanting gardenia

    Hi! I got a gardenia from Home Depot a few days ago (I live in South Florida) and I planted it in a place that gets a half a day of sun, mulch, water, and the right fertilizer, but a few of its leaves have turned yellow and it’s buds aren’t opening. Also, it starts to wilt and then regains it strength again every few hours or so! I read somewhere else that because it’s from Home Depot, it might already have a ton of fertilizer in it. Is there any truth to that? I stopped watering it a couple of days ago just in case, because I thought I may have watered it too much.

    Hi Christina
    It is going through transplant shock . No need to fertilize right now, gardenia don’t like their roots disturbed and need to acclimate to the new environment. Let the plant dry out a bit between watering to avoid overwatering . Because the roots have been disturbed, the leaves are wilting and yellowing. The damaged roots cannot send up enough water to the leaves when the sun hits them, thereby causing them to wilt. The gardenia recovers when there is less stress on the plant. Yellowing leaves will also occur as the plant tries to reduce the amount of leaves it needs to maintain. It needs time to recover.

    I am a Master Gardener and a friend brought me something I’ve never seen. The 10 year old dwarf gardenias in his yard are covered with what looks like red buls. On closer inspection, it looks like the base of the bloom never separated from the plant and has produced a seed pot. Is this possible?

    HI Paula
    Yes, its possible that you have a seed pod. Here’s a picture of a pod.Plate 14

    I have a gardenia tree, it was doing pretty well outside, since I got it inside I noticed something everyday, my latest problem was white skins on the buds & leaves was shinyy & sticky. I cut the bud & took the nursery ( the spray they gave didn’t work), my second visit he told me to clean the leafs with alcohol ( and that I think killing my plant now), I still have those white skins (not like before but still some) and now most of the leafs dried & turned dark brown. Any suggestions? what can I do about white skins? and what can I do about dry brown leafs? (it doesn’t turn yellow, just dark dry brown). Thank any info you can give me.

    Hi Ann
    Sounds like you have aphids. The white skins are cast skins of aphids. You don’t mention what kind of sprays you used. Gardenias are sensitive to insecticidal soap. A hard spray with the hose will help elliminate most but not all. Look into pyrethrin sprays labeled for gardenia. Neem and a pyrethrum/alcohol spray are also effective. Several treatments are needed in order to be effective.

    Leaf drop

    I lost most of the leafs of my gardenia tree & I trimmed some ( everyday I have dry brown leaves) even green leaves are just dry, I don’t know what’s going on, still living for now but not much leaves left & I still have that aphids ( gonna look for pyrethrin spray). thank you, any ideas about dry leaves ( not yellow) just dry (some are dark brown or black) and some green ( but dry).

    HI Ann
    In addition to the insect problem, a gardenia will drop healthy leaves when the soil and/or air moisture is too dry (low humidity). Exposure to drafts such as heating vents and air conditioning will also cause leaves to drop. Leaves that turn dark brown/black can be caused by keeping the plant too cool ( below 50 degrees). You may need to increase the humidity indoors.

  • Ann

    Thanks for your quick respond, my gardenia tree is front of the window & next to the heating vent ( even I closed the vent) it might be to dry & too cold ( for being right front of the window). I am going to move the plant from there to another place tomorrow morning. I have one more question though, I want to buy a humidifier ( for the gardenia, for the increase the humidity), which one should I get? warm or cool moisture humidifier? Thank you very much.

    I don’t know much about humidifiers, I would think the warm air one would work in the near vicinity of the plant. You can also use a pebble tray-which is a large saucer with a layer of pebbles and a layer of water just below the pebbles. Place the plant on top of the pebbles. The evaporating moisture will benefit your plant. Grouping several plant together also helps increase humidity.

  • Jennifer

    I have a gardenia bush that I planted last spring and it has grown beautifully outside. I’m concerned about it now since winter has started. I live in zone 7 and it has gotten down into the 20s some nights. I’ve noticed the bush has turned very brown even though I’ve been covering it with a sheet on the coldest nights. Will it get new growth in the spring and will it bloom? Do I need to prune the old growth back in early spring? Do gardenias usually survive winter in zone 7? I would appreciate some advice on this. It was doing so well before I would hate to see it die. Thanks!

    Hi Jennifer
    Gardenias are marginally hardy in zone 7B-with protection or a cold-hardy variety “Kleims hardy”, otherwise most are hardy in zones 9-11. It sounds like yours have been exposed to cold temperatures and that is why the leaves are tunring brown/black. It will not tolerate temperatures below 40F. If your plant is in the ground, cover it with a blanket and add a couple inches of mulch around the base of the plant to help protect the roots. If it survives the winter, you may have to prune away the dead stems in the spring.

  • Jennifer

    Thank you for answering my question above. I thought of one more thing to ask about my gardenia. If it does show signs of growth in the spring, can I transplant it into a large pot so I can move it inside during the next winter? I just wondered if moving it from the ground into a pot would kill it even more or would be ok to do. Thanks.

    Hi Jennifer
    Gardenias do not like their roots disturbed, so it won’t be happy for a while but leaving it outdoors for the winter will eventually kill it. Transplant your gardenia in late winter when it is dormant. Before transplanting, cut back some of the top growth up to 1/3 to give the roots less to feed and make the plant more manageable. Once planted water in well and give it a root starter to help stimulate new root growth.

  • Ronald

    I have a gardenia for 30 years. Now after bringing indoors for 1 month from outside, the leaves are starting to dry and turn brown to black. It’s like the plant is not getting water to its leaves. I had a problem with aphids this summer but successfully treated it and had the tree bloom during the summer. Some branches are also dry and when you break them they snap. Others are still elastic. Is the environment not humid enough? Is it possible their are aphids in the root not showing up on the leaves or branches? I also had a couple of other small gardenias which died in a similar fashion during this month after bringing indoor. Thanks

  • Suzanne

    I have a Gardenia that is wilting, has some brown spotted leaves, and some leaves are crips and almost dead. Any help would be greatly appreciated.

    Hi Suzanne
    There are some leaf spot fungal diseases that will cause brown spots on the leaves. I suspect that it started with a watering problem. If the soil is wet and the plant is wilted then you have a root rot problem. Remove any spotted leaves as it can spread and avoid wetting the foliage. Its best to water thoroughly and less often. Let the plant dry slightly before watering again.

  • tmorgan

    HI,

    I live in Alabama and bought a Gardenia Tree. It did very well till I brought it in to save it from our severe cold weather. I think it dried out way too much and my gas heat is not allowing for enough humidity. Here is my problem all my leaves except for the very tips have fallen off, I think due to lack of water and moving it into my house. I popped all the buds off at the ends because I am more concerned with surviving then it trying to bloom. It always is trying to bloom but leave production is very mild. I want it to look like a bush tree and now it looks like a naked tree does in the fall. The very end tips are green and have 2 leaves each on about 20 limbs but that’s it. Can I prune it back and make it start budding leaves again? If not when do I prune it and How? Most of the limbs are a v shaped with the middle limb cut off from when I bought it.

  • Wanda

    I am “babysitting” my daughter’s Gardenia tree. About a month ago I noticed some of the leaves had a sticky substance on them. The floor around it also had the sticky substance. The back of the leaves had black specks. Whey rub of and look dark green when in my hand.
    I have tried handwashing all the leaves. I then put the plant in the bathtub and gave it a shower.
    I noticed the stickyness and black specks are back.
    Is there something else I should do?

    Chlorosis on gardenia

    I live in South Florida and have a gardenia planted next to my east facing patio. Admittedly, I have not taken the best care of it over the years. Despite my neglect, it has somehow thrived, until recently. Over the past several months the leaves have started to turn yellow with the veins remaining green. I have tried fertilizing regularly with Miracid, but the problem persists and may even be worsening. I recently read that using distilled water, rather than tap water, may be better for gardenias. I have not yet tried that, but wanted to know if there is something else I should be doing.

    Hi Elena
    I’m assuming that your gardenia is planted in the ground. I would suggest that you test the soil ph, to make sure it is low enough(acid) to make iron available to the plant.
    Here are some other ideas, gardenias that are growing under cold conditions (below 60F) for extended periods can also become chlorotic (iron)because the cold temperatures reduce nutrient absorption. They don’t take up as much iron causing chlorosis. Chlorosis is prevalent on the new growth. It can also be a sign of root disease caused by keeping the soil too wet.
    For a quick fix add chelated iron to the soil or spray it on the leaves. If you don’t see any results in 2 weeks, try again. Another option is to apply ammonium sulfate or iron sulfate around the dripline of the soil. Follow the manufactureres label and avoid spraying any concrete, stucco etc as it will stain the surface. If that doesn’t work then there may be a problem with the roots being unable to absorb the iron and you may have to improve the soil the gardenia is growing in.

  • I am at my mothers in Naples, Florida where her gardenia has a covering of black “soot” underneath leaves, on top of the leaves as well as on some of the branches. I was told to use detergent soapy water and “clean off” each leaf. Is there anything else I can do? We have not seen any aphids or bug activity.

    Hi Elaine
    Insects such as scale and whitefly also produce honeydew which sooty mold grows on. The problem with sooty mold is that it blocks light from entering the leaves which inhibits photosynthesis (food production) which can cause yellowing leaves and leaf drop. Scale and Whitefly seem to be a favorite pest of Gardenia. For scale look closely on the stems and leaves for bumps that can be scraped off. If you brush against the shrub and little white flies emerge then you have white fly. Once you get rid of the bug, you’ll get rid of sooty mold. Easier said than done. If you have an insect problem, you can spray the plant with Orthene (acephate) Malathion or use a systemic (disulfoton) that is absorbed by the roots and renders the plant poisonous. Read the manufacturers label for safe usage.
    If your gardenia is underneath a tree that is dripping honeydew from an insect infestation, then you’ll have to control the insect in the tree. Sooty mold should wash away with winter rain or can be wiped off with soapy water. for more info. http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn74108.html

  • Eve

    I received a potted gardenia in bloom with many buds for Valentina’s. I put it in bathroom by large glass block window in large shower. Temp normal, cooler at night. I live in Melbourne, FL. It continues to bloom however the flowers turn yellow within a day or two. Leaves are green and shiny. I water when dry. I don’t take a shower in that particular bathroom often What am I doing wrong and why do flowers turn yellow in such a short time. It’s my favorite flower. My mom use to pin a flower on our slip strap as young girls for our perfume.

    Hi Eve
    Gardenia blooms in optimal condtitions will last for 3-8 days. If the plant is slightly stressed, the flowers are the first to show any symptoms. Perhaps it gets too warm with glass block window. Indirect light is better when in bloom. Flowers will fade faster is the air is too dry. It may need more humidity.

  • Chris

    Hello, I am considering purchasing a few dwarf gardenias, but have some concerns about size. Is it true that the dwarf versions only get to be about 2 ft. tall?

    Hi Chris
    I don’t know about this gardenia cultivar but if the tag is labeled to grow up to 2ft., then I would think that it should be true. Perhaps someone out there knows more about this cultivar.

  • rich

    Ilive in Cleveland Oh, and have 4 potted Gardenias the largest being 5′ tall x 3′dia in a 28″ pot +100# of soil( est.25yrs old). The smallest one is about 2′ tall,they are placed outside every summer and brought back into sun porch each fall.I have always expererinced leaf drop each fall,and sprayed them with Insecticidal soap to kill white fly and spider mites.
    But this year I had to bring them in the house due to remolding and for the 1st time I put a systemic in the soil “Bonite” House Plant insect control.In the past month I have lost all the leaves (still green)and buds turned black,from two of the smaller ones. The large one starting to do the same, HELP

  • I purchased a beautiful dwarf variegated Gardenia with double flowers, from ‘X’ nursery. True to its word, the Gardenia hasn’t exceeded 2′.
    It’s Gardenia ‘radicans’ variegata. A gorgeous plant.

    Gardenias prefer being potbound. Tight roots promote flowering, but also, the smaller the pot, the smaller the plant. I’m not saying to keep a plant confined indefinately, but smaller areas slows growth.

    Less fertilizer is another option. Althuogh, fertilizing gardinas with an acidic fertlizer is required, use half-strenght, once a month, during growing season. Halt in fall and winter.

    Someone asked why buds drop prematurely. Overwatering is the number 1 reason this happens.
    Less water and cool temps should do the trick..the problem is, the average household isn’t kept chilly. Although a few of my friends turn the heat way down at night, even in our cold area. If a person can deal with eight hours at 60-65F degrees, and soil is left to dry, buds should open, turning into beautiful blooms.

    Thanks for the info.

  • DIANE BANKS

    I live in Columbus, Ohio. I have a large Gardenia tree. They are placed outside every summer and I bring them in in the fall. It was doing well and all of a sudden I noticed that is was sticky and was covered with sap. It is even starting to drip off of it. Why is it doing this and what can I do to correct it? It is too cold to take it outside. Thanks

    Hi Diane
    Sticky honeydew- most likely candidate is scale. They love gardenias. Look for bumps on the stem and leaves.

  • Dan

    My wife has 2 Gardenia Bushes and she would like to cut some of the blooms to put in the house. How do you do this without hurting the plant?

    HI Dan
    Gardenia flowers are usually cut with a few inches of stem attached. Avoid touching the flower, it will bruise and brown easily.

  • Alice

    My husband gave me his late Mother’s gardenia tree about 3 years ago. I planted it at my home and it was doing great. About 7-8 months ago after our wedding we moved it to our new home. We were careful about having it in the “same sun” at the new location. Since moving it the leaves have become yellow and it’s rather sick looking. Of course this has a lot of sentimental value and I don’t want to lose this tree. Any suggestions would be appreciated. Help, please!
    Thanks.

    Hi Alice
    Your gardenia may be adjusting to the new environment. There are several reason why the leaves can turn yellow. Some yellowing leaves are normal, others may be because of lack of nutrients. First, check for insects such as scale .

  • Missy

    Its Missy again with another question… Its now starting to get warmer here in Northeast Conn. I have been putting my tree out when its 50 degrees and warmer to get some sun. Although now all my leaves have dried up and fell off!! It looked like there were new green buds for new leaves but they seem to have been drying up too. The soil is very moist and I try to spritz it down often. How do I make it come back? Do I trim it, do a half soil change? The stems of the tree are still alive and have green in them… help!!

    HI Missy,
    Be careful of how much sun exposure your gardenia is getting. Too much sun will easily scorch the leaves. In addition, make sure the gardenia gets a chance to dry out slightly between watering. They like moist soil but if it is too wet it causes root damage.

  • Allie

    Insect Problem
    Hi,
    I bought an indoor gardenia last year. It has started blooming again this March.
    I have seen small bugs in the pot, sticky residue on the leaves, spider web like webs on some of the leaves, and some of the new leaves look like they have been chewed.
    Please help me save this beautiful plant. Thanks.

    Hi Allie
    You may have a number of things going on. Sticky residue is a clue for scale or mealy bugs. I’m not sure what is chewing on the leaves. You may also have fungus gnats in the soil if you kept the soil too moist.

  • Missy

    Dried leaves and drop
    Hello again, Its spring here and I have put my gardenia tree outside on those nice warm days but I am sure to not give it too much sun. Since I have brought it out from the winter all of its leaves have dried up and fell off. In the beginning of the winter I treated it for spider mites with Ivory soap and water and that seemed to do the trick. The stems have green to them I have fed it a week and a half ago and still no new growth. Is this a result from the mites? Any hints? or what should I do??

    Hi Missy
    It’s possible that your gardenia tree is suffering from several problems aside from the insects, leaf drop can be due to a drastic change in temperatures (too cold) and light as well as keeping the soil too dry or too wet. They are tempremental. Keep the plant in filtered light until it shows new growth and slowy acclimate it outdoors to filtered light.

  • Judy Ellis

    Just got gifted with lush gardenia plant for Mothers Day. Tag says “Grown in Canada”. There are no blooms on it. Can I plant it outside in this 9A grow zone or is it strickly an indoor variety? I’ve got a couple spots in mind that are sunny til noonish then house shades it. Also have screened porch on same side, but I’m not to good about remembering to water stuff regularly. Thanks for your help.

    Hi Judy
    Yes, you can plant your gardenia outdoors. It should survive the winters in zone 9A. Plant it in a protected area. The am till noon sun sounds great.

  • nadine

    Hi,
    I live in a very hot country (Dubai, uae) and recently(4 months back) got a gardenia plant which was blossoming in February.
    Now that the weather is turning hot the gardenia’s leaves are curled down and some of it turning brown and it’s not blossoming at all. Today, I moved it indoors hoping that the room temperature will help. Shall I move it back outdoors?
    Any advice how to revive it?
    Thanks

    Hi Nadine
    The drying and curling leaves on a gardenia indicate uneven watering and/or low humidity.

  • Cindy

    We purchased and had a professional landscaper install 20 gardenia radicans in October 2008 going up our front steps in raised planter beds with a drip system. Are are in the SF Pensinsula and blessed with beautiful weather practically year round – no predictable/expects extremes hot or cold however occassionally a hot or cold spell which typically passes after a few days. They are planted in a Western exposure, get 6-8 hours of sun a day starting around 11am and there is occassional afternoon wind. It does not appears the plants have grown much even though we have seen alot of new bud growth. However the new bud growth turns brown (looks like they dry out)and fall off. We have seen only 10 flowers open on 20 plants. We called a specialist Nursery with certified landscaping experts and they told us to be sure the plants are not planted too deep (like azealeas) and they get plenty of water. So we increased the water (drip 10 minutes 3 times a week and now the leaves are turning yellow). We noticed that the additional water didn’t help as the buds are still dying. It appears the plant is health becuase we keep getting the new bud growth but they all dry out and fall off. Any suggestions you can offer is much appreciated – would the larger gardenias do better in their environment and can we keep them trimmed to 2 feet? We just love the gardenia and hope to have this wonderful plant welcome/dazzle all who come to the house with their beauty and scent.

    Hardiness issue
    Hi, I bought a gardenia tree and I planted it outside.I was told that it was an outside plant and now I find out that it might not survive the winter outside in Canada.When I purchased this plant I was looking for something thatwould come back th following year without any problems.
    I am very upset it is a beautifull flower and would hate to lose it… help please…

    HI Tinka
    Gardenia is a tropical plant and will not tolerate freezing temperatures. The only way it will survive you winter is if you bring it indoors. I would complain to whoever sold you the plant giving you the wrong information.

  • Amy

    I just received a gardenia plant as a gift. I bought a ceramic pot and transplanted it and added some Miracle Grow moisture control potting soil. I also added some Miracle Grow “stick” fertilizer. I have the plant in partial sun most of the day. I had it in full sun and noticed some of the leaves were turning yellow so I moved it to partial sun and the leaves look great. My only problem is “mold” growing on the top of the soil?? What is going on?? I did removed a “layer” of mold last night but it came back today. What should I do??

  • rosy

    I bought new gardenia few weeks ago with no experience in gardening and newely developed hobby.I am not sure what that yellow powder is on leaves.it is flowering and has new leaves.

    Not sure what the yellow powder is. Could it be under a blooming tree or shrub that is dropping pollen? If the powder is a light gray/white color then it could be powdery mildew.

  • mitchell

    i live north of Ocala, fla. my gardenia is about 6 ft. tall and roughly 6 ft. diameter. it is blooming nicely. do i need to pull off old flowers as they turn yellow or let them stay on plant? if i need to pull them, do i take flower and pod or just the flower. thanks.

    Hi Mitchell
    Usually the flower will fall off on its own. You can pinch off both the flower and pod. The pod (if pollinated) can produce seeds.

  • Kathy

    Pinch off flowers
    I have an outside gardenia bush and this year it is full of beautiful blooms. When the blooms begins to turn brown, do I pinch them off from the stem or do I prune them similar to roses.

    Hi Kathy
    Pinch off the browned flowers, if you don’t get to it, they will dry upand fall off by themselves.

  • lynn

    I started one from a cutting 21 years ago and it still looks and does very well. I don’t have any special secrets but this seems to work for me: I live in New jersey.
    I put it outside on my front porch from May 1st to October 1st and only feed it during that time. My porch gets afternoon sun.I feed it every 4-6 days with a pinch of Muracid to a gallon of water and let it run through.
    Before i bring it in for the winter I spray it with an all purpose bug spray and cover it with a cleaner bag for the night. Then I trim it.
    Once inside I put it in the brightest room in the house-my diningroom and water it less often and do not feed it. It sets bud over the winter and blooms on the porch over the summer. I get about 50-60 blooms.
    I repot it in the spring every few years when roots are coming out of the bottom.

    Thanks for the info Lynn. I’m sure it will be useful to our readers.

  • Michelle

    After reading the many informative posts on your website, I now see that my outdoor gardenia plant, which I planted in full sun, needs to be moved where it can be in partial sun. I live in Seattle, in Zone 8b. However, I see that you strongly recommend not disturbing their roots. Is there a good time to move a gardenia? It is now July, and I planted it about six weeks ago.

    Hi Michelle
    The best time would be when the gardenia is dormant-in the fall or late winter.

  • Kay Michaelis

    Hello,
    In late spring I purchased 4 dwarf gardenia bushes. They are planted on the border of a bed that has a small tree in the center and gets about 6 hours of sun. I was encouraged by the tag which said the plant (with its relatively tiny leaves) is hardy through zone 7 (I live in Maryland, between Baltimore and Washington D.C.) and took great care to plant them with plenty of topsoil, compost and peatmoss and fertilized them with osmicote.
    We had a very wet spring and early summer and I have been watering them (at the roots) 2-3 times a week since our weather turned hot and dry. They bloomed beautifully but in the last couple of weeks, 3 of the 4 have developed yellow leaves with brown spots. The healthy one was purchased a few days after the original 3, from a different store but the same chain. The healthy one had been trimmed back at the time of purchase and was more compact than the other 3, if that has any bearing.
    I will try the iron and miracid that you suggested and see if it helps the yellowing. However, after reading some of the comments about wintering, I’m concerned that the plants will not last through our cold season, when our temps are generally in the mid 30’s but at times can get down into the teens.
    These plants have a warranty of a year, but I’m wondering if I shouldn’t return them now. Even if they last until spring, it sounds as though each year would be a roll of the dice as to their survival. If I do keep them, should I keep them blanketed for the whole winter, removing the protection only when the days are unusually mild?
    I will appreciate your comments about the yellow leaves and chances for survival. Thank you and take good care.

    We have a large indoor plant and we have noticed a white type of mold on the branches and leaves .It is sticky when we touch it and the leaves of the plant on the inside have turn brown /black what can we do about this?

    Hi Dan
    I suspect that you may have mealy bugs or powdery mildew, (altough pm is not sticky) on your gardenia.

    I have a couple month old gardenia which got infested with spider mites.So, I sprayed it with bayer.The bugs are gone.It has new leaves and setting new buds.But the new buds have green outercovering when opens up but nothing inside i.e. no petals.Please, tell me what to do

  • rosy

    My gardenia is setting buds.It has green outercvering that is lot longer than appearing tiny buds.Could someone please tell me how the buds look like when they are forming.

    Hi Rosy
    The buds will expand and get plumper and should turn a light green color. As the get larger, they will turn white.

  • seth akshay

    i live in northern va and have just bought a gardenia jasminoides ‘aimee’. It is about 3 feet tall and is potted. As adviced by the nursery i fed it Miracid, however its leaves started getting yellow. i would like to know how to take care of this beautiful plant. The zone of this area is 7b.

    HI Seth
    Some leaf yellowing is normal. Miracid is a good fertilzer for Gardenia. It may take a week to notice the difference. Are the older leaves turning yellow or the new leaves? You can plant your gardenia outdoors as it it hardy in zone 7b.in afternoon shade. Plant it in rich, well-drained slightly acid soil. Once planted, water well and place 2-3″ of mulch around the plant, keeping it away from the base.

    Drying and curling leaves
    Hi. I live in Atlanta. I replanted my gardenia last spring. but after i did. the green color of the leaves seems to fadded, it is not losong the green color, very dry leaves and curling at the end. what to do?

    Hi Naomi
    The drying and curling leaves on a gardenia indicate uneven watering and/or low humidity.

  • Pat

    One more variation on the endless yellowing leaves issue: This spring, I planted some Radicans dwarf gardenias in a relatively low-lying bed that has tended to stay damp. Recognizing that, I planted them fairly high, did the best I could to prepare the hole for good drainage (underlying soil is clay), and tried not to irrigate too heavily. Half of the plants seem to be doing well, while the others are thin and have many yellow leaves. Contrary to what I would have expected, the plants doing better are in the section of the bed I think is the dampest. How likely is it the the yellow leaves on the others are due to being UNDER watered? The surface of the soil does dry out between waterings. Any other thoughts? We’ve had our soil tested and it is acidic. Site is mostly sunny, zone 8. Thanks.

    Hi Pat
    I’m asuming that you checked for insects and nutrition problems. It is possible that the yellow leaves are due to not enough soil moisture. Gardenias like slightly moist soil. Try placing 2 inches of mulch around the root zone of the plant. This will help keep the soil moist longer.

  • Tish

    Hi,
    I live in Toronto Canada and I have an indoor gardenia facing North which is the brighest room in my home. My gardenia had a mealybug problem which I think is now controlled, however I have no leaves or buds on my plant but the plant still looks like its alive. Any idea of what I should be doing now. Thank you for this wonderful and informative site. I would love to be able to succeed with my gardenia as I have not had many good results before.
    Thank you

  • Vicki

    Hello- We bought a gardenia bush this spring and planted it in a pot–We live in VA and I know it won’t make it for the winter. I also know that bringing it indoors might be a problem due to temp’s in the house and dry air. Could I wrap the plant in burlap and put it under the deck or in the garage? or make a tent for it with plastic sheeting?

    Winterover gardenia indoors
    I purchased a blooming gardenia in April, repotted it and put it in a sunny spot outside. I live in Missouri. It’s grown considerably! I only had one bud on it, then we had a rain storm and the bud knocked off (no more buds). Now day temps are only in the mid 60’s with nights in the 40’s. I have doubts that it will survive the winter indoors because windows are east/west exposure. Do you think I could just put it in the basement and let it go dormant for the winter and revive again in the spring? I’ve never had success with indoor gardenias over the winter. H E L P please?

    Hi Sylvia
    I have never tired it but as a last resort, I think its worth a try. Other tropical plants can be wintered over the same way. Just make sure that the soil doesn’t dry out completely-water it lightly once a month.

    Perhaps someone else out there has had some experience with this method.

  • Megan

    Leaf drop
    I brought my gardenia inside for the winter…and it was fine at first, but now ALL of the leaves are dropping off. What does that mean?

    Hi Megan
    Lower light and dryer air can cause your gardenia to drop its leaves. Provide bright filtered light, uniform moisture and humidity (place it on a pebble tray)
    Are the leaves turning yellow before dropping ?
