Mandevilla
Mandevilla care and tips
Mandevilla belongs to a large family that also includes plants that were formerly known as Dipladenia. It was named after a British diplomat/gardener Henry Mandeville. This exotic plant bears trumpet shaped flowers in shades of pink, yellow and white (some fragrant) on twining vines with puckered, oval leaves.
This tropical plant is hardy (depending on cultivars) in zones 9-11 and is for the most part of the U.S. treated as a houseplant. It is grown outdoors for the summer and in colder regions taken indoors to endure the winter.
Care
Outdoors:
Mandevilla is cold sensitive and can be taken outdoors after the danger of frost has passed and night time temperatures are over 50ºF. It prefers full sun to part shade in the summer and a deep rich, well-drained soil.
It will also need a trellis to support its long trailing vines. Provide plenty of water during the hot days of summer. To keep a healthy blooming plant, feed it every other week with a high phosphorus fertilizer (10-20-10) in the spring and summer. In order to maintain the tangled growth during the season, pinch off new shoot tips which will produce a bushier plant. Trimming will not reduce flowering as it blooms on new growth.
Propagation
Mandevilla can be started from seed at temperatures of 70-80ºF. A faster way is to take cuttings in the spring and summer which will root and develop new plants. More info on how to Propagate Mandevilla.
Watch out for mealybugs, scales, whitefllies and red spider mites.

I live in PA. I have a mandevilla that was beautiful last summer. I cut it back to bring it inside for the winter. It was getting new green vines growing, but after I put it back outside when the weather was nice, it now looks like it is dead. It still has a few green leaves, but the stems are brown. What happened?
Are these plants toxic to dogs?
I’m in Zone 9 in north central Florida. I bought a mandevilla last year and put it in a large pot in my garden. It was not getting enough sun. This Spring, I transplanted it to a larger pot and moved it onto the patio where it gets at least six hours of sun. I fertilize every couple weeks: with plan fertilizer and then with acid-loving plants fertilizer and then with bloom booster. I finally see the first yellow bloom! However, every day my plant drops about five or six healthy looking green leaves. These leaves are not turning yellow and there is no spot on them. What am I doing wrong?
Hi mine loves the trellis it died back over the winter and produced 3 fruits, are they safe to eat? If not I can always get more seeds from them. I have a yellow one with the shinny leaves.
Hi, I’m in Michigan. My Mandevilla is very healthy w/flowers but it’s all in clump w/a very few vines. I have a beautiful trellis but it doesn’t seem to like it. What can I do?
I have a yellow mandevilla and the buds are rotting at the base where its attached to the plant. What causes this?
Hi,
My mother brought me a red mandevilla home from Florida to nj. She cut it back as she thought it was getting too big for her house and it stopped flowering as she kept it inside for a month. She gave it to me mid May and I immediately planted it. It is now the end of June and it is growing like crazy but not one sign of a bloom. It gets plenty of sun and water, and it looks very healthy.
What can I do to make it bloom?
My plant is woody at the bottom but green leafy and viny at the top with flowers
Flowers and leaves have brown spots and it’s exposed to full light
How do I make it more fuller with leaves and flowers?
Thank you very much for the reply. I do have a quick question. Do Mandeville’s bloom off and on through the summer or do they bloom continually? The blooms are declining a bit so can I assume It’s taking a rest In-between bloom cycles? I did just fed some bloom bloom boost just the other day. It seems like only one side has been blooming only. Thanks.
I recently purchased 2 Mandevillas and will need to bring them in for overwintering. I don’t want too large of a pot since I will have to bring it indoors so I don’t know how large of a pot is required?
My mandevilla buds but the buds don’t open, start to rot and drop off. Morning sun, and last year in the same place did fine until scaley stickey stuff appeared late summer.
Thanks.
Petal blight
I purchased a white mandevilla last week. It has numerous flowers but the petals are turning brown and the flowers are falling off. Fortunately, I separated it from my other two which do not have this problem. Help please.

Petal blight treatment
We have had rain almost daily for weeks, I would not be at all surprised if this was the problem. How to I handle petal blight organically?
Thanks for the quick reply.
Robin
Spider mites
I have 2 mandevilla plants. One’s leaves are dark green and plentiful.
The other day I noticed my other plant’s leaves are mottled, and light-green/yellowish. I also noticed that it has far fewer leaves.
Upon very close inspection, I saw all these delicate little webs, and the tiniest little bugs! EWWWW!!!!
I live in southern Michigan and have had these plants… AND THESE BUGS!… in my house all winter long!????!? WHAT IS IT?
Also, is it recommended to change out the soil in the pots after winter, before acclimating them to the outdoors?
Nutrient deficiency
Hi I was wondering if anyone knew if Mandevilla was prone to either Iron or Manganese deficiency? I have some in a bedding plant greenhouse and the new growth is showing some interveinal chlorosis starting from the base of the leaf (tips are still green?).
new growth dieback
I put my mandevilla outside last week and it was in the 60’s and 70’s during the day, but got cold at night (never below freezing though). On one or 2 of the days it was outside it was really windy. I brought it in when I realized it was going to go below freezing. All the new growth it had formed while being indside during the winter has died and there is no green on the plant. Did the cold from one or 2 nights kill it or is it just dormant?
Yellowing leaves from flowers
I know this sounds crazy, but we have been growing mandevilla (Alice Dupont) in pots, training them to grow up the posts on our porch for 8 years. (We buy new every year) We have often wondered why our ilex crenata planted around our porch yellows, and dies. It is only the plants that are under the Mandevilla that are dying. What happens is the spent pink flowers drop on top of the ilex, and that’s where it yellows?????????? Has anyone ever heard of the flowers being toxic??
They say the Mandevilla is related to a plant that is toxic?? Thanks
This is my first experience with the Manevilla plant. I purchased two and have them planted in full sun in large pots on an outdoor patio. One of them died, so purchased another to replace it and this one is being infested with sticky orage, what I think are aphids. What can I do to get rid of them?
Brown leaves
I live in west Texas, where we have had 30 100+ degree days so far this year. I’ve been successfully growing Mandevilla in pots for a few years. This year I found some in hanging baskets which are perfect for my east-facing balcony. They have done beautifully until 3 days ago when I discovered several of the upper leaves are turning brown on the tips, then gradually the whole leaf withers and dies. This isn’t like the disease where the leaves develop small purplish spots, then turn yellow and fall off. It’s more of a rusty color. I water once a day (being in hanging baskets they drain well)and fertilize every 2 weeks. I haven’t seen this condition before. Help!
It sounds like you have a Dipladenia.
I maybe wrong but the leaves are a darker green thicker and the flowers are a very dark red?? I live in Summerville I grow both. The Mandivilla I use a 2 foot pot and 9 foot bamboo poles stuck in it as a trellis. I use electrical wire to hold them together. they grew 9ft in 3 weeks.
Wintered over not blooming
My mandevilla plant looks healthy, but is producing no flowers. This is a potted plant, second year, and receives approximately 6 hours of strong sunlight per day. Last year this potted plant flowered all season, in the same location. Any advice? Thank you.
Propagate and winterize mandevilla
We would like to start our own mandevilla plants in a indoor green house are they easy to raise? We live in upstate new york and have cold winters, can we bring them in in the fall and keep them going until spring?
Poisonous
Is this plant poisonus to animals?
Small dogs and cat
Hi — my mandevilla did beautifully last summer but when I put it back out this year it developed small brown spots all over each leaf and isn’t growing well…is this a fungus or a bug — what should I do? Perhaps it needs to be fertilized?
Low light/no flowers
I’m in Denver and trying desperately to get my first Mandy to survive the winter. I have it by a west-facing window with a sheer curtain, and I also have a grow light on it, but I’m not sure how it’s doing. I whacked the heck out of it about a month or so ago and it seems to have quite a bit of new growth (lots of new little leaves where I whacked it, no flowers though), but it’s also dropping leaves like crazy. Is this normal or am I doing something wrong? I have not fed it at all since I brought it in around the middle of Oct., it does dry out before I water it, and I try to keep the temp around 65 (if I could get my hubby to leave the thermostat alone). Does it need more light, less light, fertilizer, etc.?
Feeding indoor mandevilla in winter
Are you supposed to keep fertilizing the mandevila plant during the winter while it’s kept inside?
Poisonous Plant?
Hi,
I have a Mandevilla that I brought inside to ride out the winter. My problem is that my cats think it’s a salad bar. My main question is, is this considered a poisonous plant and should I disgard it? I’ve seen conflicting posts and would like an educated answer before I throw out the plant. Thanks.
Cat repellant
I have 4 cats that nibble on plants. Will Mandevilla red or Bright Light harm them?
Propagate mandevilla tip
To make cuttings I use “kys-cubes” which you may be able to get from a nursery or greenhouse operation. Keep them wet and mist them often, out of direct sunlight. They’re a little slow to root. If trying in cool or cold weather bottom heat will help.
Sunny, concerning cuttings, I forgot to say that I take a terminal stem with about 3/4 inch below a pair of leaves. Insert the piece into the cube so that the leaves just barely wedge into the cube, which helps to stabilize it. Also, the use of a rooting hormone will help.
Larry, I’m curious. How are you doing the cuttings? I’ve tried a few times and it never worked.
We have 2 pink Mandavillas (2 years old) and both were healthy until 2 weeks ago. I live in Northern California- we noticed a “white dust subtance” on the leaves, eventually turning into tiny black dots with a sticky “tar like” subtance. It’s killing our leaves and flowers. Please help!
Overwatering
I had three mandivillas, but now only two. They all seem to be doing the same thing. They were thriving before the hot temps (90-100). They are well watered, but they begin with yellow and browning leaves, and this seems to travel up the plant all the way to all of the new growth. Eventually, they die. They are all near a sprinkler. Could they be getting too much water?
Thanks,
Billie
Leaf spot disease
I have Mandevilla plants in large pots on each side of my spa on the pool decking. I have noticed the leaves yellowing with black spots. Do I have aphids or what could be causing this?
Not blooming
I purchased a Mandevilla vine about 6 weeks ago, great looking plant but no blooms when i bought it. I repotted in a hanging planter on my back patio, here in Central Florida. The plant looks great, very healthy and some new growth, but no blooms still!! Am i doing something wrong? It gets full sun. Thanks for help!
Yellow leaves
I have two pink mandevillas in large pots which were doing very well since the beginning of June and now, all of a sudden they have lots of yellowing leaves. The pots have good drainage but it has been extremely hot here in Illinois for the past two weeks. Can yellowing leaves be from the heat? The plants are on a rooftop deck and get sun most of the day.
Trimming
i purchased 2 mandevillas this past spring for my apartment patio. i inserted bamboo arches into each one and the vines really twisted around them. i want to take out the bamboo supports and let the plants “catch onto” the balcony railings. problem is, i would need to majorly trim them in order to untangled and remove the supports.
is this a bad idea to do this now, in the middle of july? will it really affect them or harm them?
Insects
I have three beautiful Mandevillas that I planted at the beach in 8in by four foot pots and added white fan trellises. They are doing beautiful but one now has little black somethings and some ants. I sprayed with a solution of dish soap and Dreft and water. I just love these plants. Thanks for all the information. Since they were expensive I will try to over winter them following the advice of the three day prep and then clear plastic bags. Next year I will put more in as they are just so cheerful,and beautiful. Again thanks for the advice!
spots on the flowers
I just got a Mandevilla a couple weeks ago. I live in Oklahoma and have lots of clay in our soil. We have had some of the flowers fall off and also have white spots on the flowers. Is this because I am watering it too much? Our weather has been in the 90’s. Could it also be from the shock of replanting?
Reading this site has made me feel much more confident in caring for my expensive special mandevillas, as well as showing me where to buy things- glad I found this!- but also I was left with a question. All the info I have gathered through the years on flowering plants tells me that removing the seed pods before they mature encourages more flowering. Is this not true with Mandevillas? I would like to try the seed pods, but not at the expense of flowering beauty.
Bud drop
I just purchase a giant crimson mandevilla plant about 3′ high. It’s beautiful but all the new buds are dropping off. Why?
My son just bought me a beautiful Mandevilla in a pot which has a small trellis. I live in Illinois, and wonder if I should leave in the pot, or when the temp. doesn’t get below 50 at night, transplant in the ground. I have had it inside right now, and the blooms are falling off, but I know it isn’t getting near enough sun. Any thought’s would be much appreciated! Thanks so much! I don’t want to kill it as it is such a beautiful gift from my son!
Watering mandevilla
I just got a brand new Mandevilla for Mother’s day and I just had a question about over watering. I have never had one before so I dont want it to die. How much water is too much? I live in San Antonio so its very Humid and the dirt seems to dry out really fast at the end of the day. Should I water it more when it’s like that or just wait to water it the next day or even the next week? When you do water it, How much water should I put in the pot? I really like it and want to make sure I do everything to keep it alive. Thank you.
I puchased two mandavilles last summer and planted them in hanging pots. They both thrived all summer long. I brought them in for the winter and left them in their hanging pots in front of two windows so they would get plenty of sun. I watered them when the soil was dry and gave them plant food once a month. They died slowly but surly. They just dried up and no amount of water I gave them would help. I dont know what I did wrong… please help.
Spider mite problem
I am following up to the message I sent in last night. I found webbing on my plant this morning; it wasn’t there before. I’m guessing spider mites. What is the best way to get rid of them and keep them from spreading to my other plants or coming back? I have placed this plant back outside for the time being since the temps are back in the 50’s here. Thanks again for your help!
I was just reading over the comments on here and was really surprised by the number of people having problems with their mandevillas. Some observations: the pink is the strongest of the types – reds and whites don’t seem to be as vigorous. For two years I’ve grown mine on either side of the entrance to my front porch – eastern exposure – full sun until around noon. On one side there is a downspout from the rain gutters – that plant gets lots of water and, while it has good drainage, the ground stays wet – IT DOES GREAT! The other plant (while it still does well) is only about 1/2 to 2/3 the size – I try to keep it watered every few days. I don’t try to save mine when the cold weather comes here in North Carolina – they are cheap enough to replace each year. I think that since mine are never really stressed may be the reason I never have bug issues.
I do have a question however – in a tropical setting without a dry season – do these plants flower 12 months a year?
Hello. I am new with Mandevilla. I live in Orlando and have three (2 red and one pink) that i purchased about 2-3 months ago. It has been amazingly hot here (over 95) and these poor guys are right in the blistering heat. I have sandy soil and have been making sure to water them more due to the intense (and unusual) heat. But all growth has stopped and the leaves are yellowing. In fact, the red ones seem to be shrinking. What can I do to save them?
Adding on to my post, we were looking for the 10-20-10 combo for plant food but the best we have in our area that even comes close is 15-30-15 which is the same ratio just higher levels of each. We didn’t get it yet. The other option of course is Miracle Grow’s 20-20-20 all purpose. Thoughts
Deer resistant
I just bought 2 mandevilla plants and want to put them outside for the summer. Do deer eat mandevilla?
Pruning Mandevilla
I live in Houston, TX and have two mandevillas in my back yard, shaded with 30 – 40 ft magnolia and live oaks. These plants had taken over the back yard and were climbing all over the trees. Two years ago, I decided to have them cut to the ground (taking part of the magnolia and live oaks with them). They are growing back fine. I’m training them to follow my fence, rather than climb the trees. So far they have not bloomed. Do they need full sun to bloom or is it just a matter of time? They get more sun now that the trees had to be trimmed. Also, what is the best time to trim these? They are very hardy and have lived through all our winters. I would love some flowers, but need to control their growth some. Thank you.
I bought my Mandevilla on clearance and it only had one flower on it. Since then I have repotted it and fertilized it but still no flowers. The leaves are growing with new stems, however I don’t see any signs of flower buds. Did I buy a lemon?
I bought 4 mandavilla’s for my porch, the containers they came in did not have any drainage holes so they held alot of water, 3 of the plants leaves turned brown only 1 new shoot on each how can I save my plant? No new leaf growth either.
Poisonous
Are mandevilla vines or plants poisonous to dogs?
I HAVE A MANDEVILLA PLANT I HAD LAST SUMMER. I TOOK IT IN FOR THE WINTER. KNOW THE DIRT LEVEL HAS DROPPED ABOUT 6 INCHES BELOW THE POT. HOW DO I TREAT THIS CONDITION?
*Mandevilla care tips
I have 18 plants-most from cuttings.
Here’s what I’ve done every year and, so far it works. Do this BEFORE the night time temps get below 40.
Prepare for winter
1)a WEEK before you are planning to move it inside, feed it well. The plan is to get it strong for the winter hibernation. WATER IT WELL THE DAY BEFORE OR MORNING OF YOUR PLANNED REMOVAL.
2)on the day of removal, cut it back to about 1 – 1 1/2 feet from the soil with one good chop. Clean up the severed vines and discard.
3)press your shovel ALL THE WAY TO THE GROUND in a circle around the plant about 6 inches from growth. Gently lift the plant out and place it in a pot that will hold it for the Winter.
3)give it some water but not enough to run out of the pot.
4)place the whole thing in a clear plastic trash bag and put it in a place that will not get below 40 degrees in the winter. A heated garage, a basement or a cool room. Tie the bag closed so that it will stay humid and dry out very slowly allowing the plant to adjust slowly. Here’s something that I do: once I put the plant in the bag, I give the plant a quick, LIGHT shot of all-purpose bug killer and then I tie the bag up. It seems to kill off anything that thinks it might hang out on the plant for the winter.
5)now, forget about it until Spring.
SPRING:
Remove 2 shovels full of soil from the spot where you plan to put your Mandevilla. Fill in the spot with 2 shovels full of organic matter (compost) and sir it up and over very well. This will give the plant a happy home for the season. Remember to keep about half of the soil that is on the roots in the pot when transplanting.
when the night temps are 40 or higher (in New Jersey I wait until April 20th)I move them outside, discard the plastic bag and water JUST A LITTLE. Because it hasn’t been in the sun for a few months, the leaves will burn. That’s normal. It WILL look dead and will lose any leaves that sprouted. This is normal. Just clean it up and know that this is the way the plant adjusts to the sun. Water it gently a few times until you are ready to put it in the ground. May 1st is when I plant mine.
Before storing your containers for the summer, remember to wash them out with bleach and a mild dish detergent to kill off anything that’s not supposed to be there.
Fertilize weekly with a weak solution of all purpose food.
ENJOY FOR THE ENTIRE SUMMER!!
Thanks for the insightful comment!
I just purchased two Mandevilla plants to brighten-up the sunny area in front of my brickfront townhouse. I saw the plant flourish last summer nearby and fell in love. Unfortunately, I didn’t do much research before buying it and need help. I currently have it outside (4/23/09) and am concerned about temp. I’m not sure if the commercial brand potting soil is right for this plant. I’m hoping to get advice on whether these plants should be out yet, how I should treat the soil, and how I can maintain them throughout the spring and summer months.
have a pair of white mandevilla planted outside on trellis in 2/09. both were flourishing until about 3 weeks ago. one continues to look great. other has wilted leaves and some dead shoots. replanted wilted one 2 weeks ago thinking it might be getting water trapped at roots. gave it some fertilizer. do not see any signs of insects. wilted one looks same except more dead leaves, shoots, etc. what would you suggest as next step?
Hi and thank you for your speedy reply–awesome. The only thing is where we are, it will not get to be in the 50’s at night until mid June anyway and gets cold in September. What should I do for the interim? Also, I noticed that the plant has a double container–the one in which the plant is in has drainage holes and the other outer one has no holes, so I’m wondering if the plant is sitting in water and is suffering root rot. If I water it just a bit when needed–the soil will be hard, hard on top, but the soil at the bottom is wet. This is why I was thinking it needed to have new soil that is “dry” to absorb any excess moisture and top dress it with new soil. Is it OK to leave it in that type of pot being that it should not sit in water? (sorry for all the q’s–just frustrated as I’m pretty good with plants) Thanks again.:)
Hi. I seem to have had bad luck with these plants. I’m on my third new one and the leaves become mottled, turn yellow, then brown until they dry up and fall off (along with the buds). It looks awful and may not make it. I do try to keep it in the sunnier room but not direct. I try to watch it does not dry out but wondering if the soil needs replacing even though it has been here for a month so chances are it is me, not the soil. I’ve tried a mild fertilizer. They are expensive to buy here and wondering what I am doing wrong. I live in northern Ontario, Canada. Thank you so much in advance.
i was just wondering if there is a specific bird or butterfly that like the Mandevilla?
Pruning mandevilla
Hello, I purchased three Mandevilla plants through ebay. They arrived last week in great shape and in the bare root form. I planted them in 100% very well seasoned compost. They are about 2 to 3 feet tall. They are doing pretty well. Lost a few leaves but other wise OK. My question is. Can I cut them back to make them bushier or will that be too hard on them? If not then when? We live in St. Louis. I do not expect to set them out for another 60 days. Will I have to harden them off at that time? Do I harden them off just like a young perennial or annual seedling? Best regards
I have aphids on my Mandevilla plant that I have in my kitchen for winter storage. I want to get rid of the aphids without spraying a chemical in my house . Is there anything that will treat them by adding to the pot of soil it is planted in. It’s a huge vine and praying it would be difficult inside my home. This happened to my mandevilla last year inside the house and it lost every leaf. I put Rosebush insect treatment in the soil and it didn’t work, then I bought an indoor aphid spray and sprayed the few leaves and the vine . It suffered so much I cut it back . It grew when put out in the spring but never bloomed. Now what can I do. It was doing so good inside until now.
What can I do? Any suggestions would be greatly appreciated.
My mandevilla has tiny ants all over the leaves and the blooms and also yellow stuff, kind of looks like very tiny eggs.
Cold damage
I live in Orlando, FL and have multiple gorgeous mandevilla plants growing over the fence around my back yard. We recently had several very cold nights, including a hard frost, and all my mandevilla have turned completely brown. Are they dead? Will they come back? Do I cut them back to the base of the plants?
Pruning Mandevilla
I live in Clearwater, FL and want to cut back my potted mandevilla vine to rejuvenate new growth. How far back is recommended? Should it be to the old growth? I would like to get flowers throughout, not only on the tips.
I have a pot of Mandevillas that have bloomed. My question is does the Mandevilla come with the trumpet type flower as seen on most sites and also a double or rose type bloom? Mine has both on the same plant. The double one almost looks like a carnation with large petals around it. Is this normal?
Slow to bloom
I pulled up my Mandevilla this spring thinking it was dead but discovered a sprout from one of the fleshy roots so I replanted it into a large pot. It finally recovered from the shock and has lots of leaves/vines but no blooms. It bloomed into the fall last year. Any ideas?
Thanks,
Sheryl (south Louisiana)
Start from tubers
Is it possible to start a mandevilla from the tubers of an older plant? Just the tubers, not the whole root.
I purchased a hanging potted mandevilla…then discovered it will climb…can I place it near a trellis or what works best for Midwest weather?
Tubers
I live in Savannah GA & did not bring my Mandevilla in for the winter. When I dug it out of its planter, it had many healthy looking tuberous roots. Can I replant the root/tubers and expect them to grow? How long to maturity?
Leaf spot disease
I have brown spots on my mandevilla vine leaf especially near the veining. What is this and what do I do?
Spider mites
Can spider mites kill or harm my plant? How often/long should I treat the plant for? Since its indoor how often should I water? You have been very helpful. Hope you and your family have a safe and enjoyable holidays.
I live in Santa Monica, CA. I would like to plant Mandevilla on a trellis that is 15 feet high. It gets partial afternoon sun on the west side of the house. Will they survive in these conditions. How many plants need to cover fifteen feet spread? All the best. Steve
Not blooming
We received a mandevilla last summer, put it in the ground at our NJ home, and watched it bloom prolifically. We brought it inside in the fall, and it sent up new shoots about February. After the last frost, we moved it to the same outdoor spot it was in last year. Though it has grown well since then, it hasn’t bloomed. Please advise. JS
Jeanette Johnson
My mandevilla appears to be growing healthy and happy. I have it in a sunny location, out doors. I am feeding it a liquid feed three times per week, Miracle Grow All Purpose 24-8-16. I am getting no flowers. How come?
Epsom salt
I had inquired about a beautiful Mandevillea and was told that Epson salt was scratched in the soil that made it look so pretty. I was wondering if you heard anything about this trick?
speed up flowering
I have a question on flowering of the mandevilla. This is my third year with the plant, I have done everything that you suggested when it comes to winter storage and fertilizing. I live in Ontario, Canada and wanted to know if there is any way to speed up the flowering. I know the flowers come from the heat. It seems like my flowers really on come in August-September I was wondering is there any way to get flowering going earlier… say late June?
Thanks Paul
I am trying to find some photos of a Mandevilla. We have a vine with large red flowers and have been told it is a Mandevilla but the only info I can find tells me the Mandevilla is pink or white. Please help
I also have mandevillas that are turning brown and dying. I have already lost two this summer and two more that are dying. The leaves turn brown mostly on the tips and outer edges first then move to the whole leaf. Some of the flower buds also turn brown. They also have long shoots with no leaves or flowers. They have done well in past years.
Ants on plant
My mandevilla has tiny ants all over the leaves and the blooms and also yellow stuff, kind of looks like very tiny eggs.
I know this is going to strike you as funny but my husband has a goat that keeps eating the ends of my mandevilla vine. what can I do to stop this? (short of shooting the goat)
Yellow leaf drop
Regarding the Mandevilla – I live in Dana Point, California right on the coast. It’s temperate here and never drops below 50 degrees. Still, my plant leaves are getting sparse and yellow. What should I do?
Whitefly
What are the white, flying bugs that look kind of like aphids? Are they aphids and how do I get rid of them? Also, what kind of damage do they do to Mandevillas? Thank you, Christa
