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 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 therefore is for the most part of the U.S. treated as a houseplant. It is grown outdoors for the summer and in cold weather taken indoors to endure the winter.
Care
Outdoors: Mandevilla is cold sensitive and can be taken outdoors when the danger of frost has passed and overnight temperatures reach over 50ºF. It likes 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. Use the cuttings to make new plants.
Propagation
It can be started from seed at temperatures of 70-80ºF. A faster way is to take cuttings in the spring and summer which will easily root and develop new plants. More info on how to Propagate Mandevilla.
Watch out for mealybugs, scales, whitefllies and red spider mites.

HELP!!! My Grandmother gave me this beautiful crimson red mandevilla and it bloomed and had beautiful dark green vines and leaves this past summer. This winter I had it in an outside room and I assume it got too cold and I brought it in the house, its leaves were droopy and brownish green, I watered it, now its leaves have dried out and are falling off, I repotted it in hopes that this would help, is it dead? can I save it? Please HELP!!!!
My mandevilla has lost almost all its leaves in a matter of a few days. I have had it about 6 weeks and I transplanted it and situated it according to directions. I have been letting it dry out between waterings. It never flowered, just kind of sat there, and then some leaves dried up and fell off and others just fell off. I don’t see any evidence of fungus or bugs (no bumps, spots or webs). I have cleaned up all the leaves and cut the dead vines back. Did I just get a worn out old plant that was ready to die?
Many thanks for posting “Mandevilla”. I personallymay really wind
up being coming back for alot more reading and commenting soon.
Thanks, Beatriz
I want to keep my mandevillas comfortable in 12″ pots as I cannot pick them up to bring them indoors in the larger pots. How do I keep them from becoming root bound and how can I control their growth? Should I clip the roots periodically? I also need to control their height. They begin to produce leaves in Feb. Wouldn’t it be best to prune them back by 1/3rd.in the fall? Sorry about so many questions. Thank you. Robin
Hi, We bought a white and red Mandevilla a month or so ago and planted them in the ground in the corner of our yard with a nice trellis, used a good Mirical grow soil when we planted them. They get good drainage, but it has been very hot and dry here so been watering everyother day. (we live in south Texas, been in the 100′s) Planted both the same, in same corner across from each other to fill the corner. Now the white one seems to be dieing. Part of it just lost all its leaves, and turned brown, part of it looks ok and trying to put on blooms, but then some is starting to get yellow leaves. The red one looks great. Did we water to much thinking it was to dry, they are in full sun, is it just to hot on them. What do you think
Hi Kary 1
Yes, every other day is/was to much of a good thing. wait until the leaves start to droop and then use water sparingly.
So no one has any answers for Tonimac? I forgot to mention that I planted in the ground because my son was so disappointed I didnt have planted in the ground. THought I would just dig up and put in pot for the winter months.
Encourage blooming after wintering
I bought my plant last year. It bloomed all summer. I brought it in for the winter. I’ve taken it back outside this spring, I’ve fertilized with bloom burst. The leaves look healthy and there are vines growing but there are no signs of blooms. We live in Mo. Help.
Hi I live in Louisville ky which is zone 6, I recently bought 2 giant crimson growing well and look great. Will Ibe able to keep these plants through the winter and if so how will I go about maintaining them
Hello:
My Crimson Mandevilla was beautiful when I first received it about 5 weeks ago as a gift. It was very lush with thick, waxy, dark green leaves and plenty of hearty crimson blossoms. I’t in the sun half the day and shade the rest. I definitely think I did a few things wrong including overwatering it and also spritzing the whole plant lightly with water a few times. I don’t have it up against a lattice yet as it’s still in the orginal pot and just up against a fence. Before I had the chance to let it dry out (from the overwatering) the leaves started to change color with some yellow showing up in the middle, along the veins, and the texture of the leaves became sort of rough. A lot of leaves actually turned brown and fell off and the blossoms have turned dark and fallen off as well…not all of them but most of them. I noticed that spiders have moved into a lot of flowers as it appears to be a good place for them to put a small web. Also, some of the leaves appear to be changing shape overnight with one side of the leaf losing it’s regular curve and having a new “S” like shape instead. I do plan on getting the lattice set up ASAP as the top parts of the plant are too heavy to stay up on their own and seem to be suffering because of this and getting very weak and droopy. I really loved the original look of this plant and would like to restore it to it’s initial beauty if possible. I don’t know if I just overwatered it or if something else is going on. Help! Thanks : )
I have grown Mandevilla’s sucessfully for the past 5 years, until this year. Some of the leaves are brown and dry along the edges and the pink flowers are white along the edges of the petal. The flowers are a lot smaller in size too. Can you suggest a remedy?
Thank you for this site.
Faye
I should have added that I did use a different soil this year. Suppose to be comparable to the Miracle grow stuff. I am also fertilizing with the miracle grow every 2 weeks. I have it planted in a big pot outside and it has been outside since shortly before Memorial Day here in Wi. Weather has been favorable here.
My mandevillas are really doing well but I noticed yellow stuff on the offshooting vines. Are these bugs or pollen? Bad or good. Do I need to do anything to them?
I too, have just noticed this yellow stuff on the offshooting vines. I’ve used an fuguscide and sprayed all over. I hope I don’t kill it as the red and white flowers intertwine themselves and are lovely. Any thoughts from anyone on what this might be?
can you send a picture?
Did anyone find out what the “yellow stuff” on the stems towards the ends of the branches is? I do not think pollen because it is too far away from the blossoms. I’ve been cutting them off. Plant seems healthy.
My red mandevilla’s started off with beautiful deep red flowers, and now the flowers look washed out, and loosing color. leaves are fine. Plant has part sun, plenty of water and has added fertilizer. Please help?
Hi Lisa
too much direct sun will tend to fade the flowers.
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.
Robin
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
Repot mandevilla
I just bought a beautiful potted mandevilla and was wondering if I should repot it to a larger pot. Do they prefer to be root bound? If I transplant it will regular potting mix work? Thank you.
Hi, I bought a new mandevilla just the other day and repotted it and watered it.
Not the Blooms that were on it are droopy and the leaves are droopy and it seems like it is not doing well at all.
It is under a porch and not in full sun all day but in the afternoon it gets a few hours.
Do you think I have overwatered it? The leaves are also turning yellow.
Please help! I love Mandevillas!
Leaf drop
Hello,
3 weeks ago I bought a crimson mandevilla in Ikea, and within a few days it started losing leaves. On the 2nd week the flowers and many of the leaves completely dried and fell off, and now I’m left with about 1/3 of the leaves…
I keep it indoors, on a windowsill. I water it about 3 times a week, and when I touch the soil on the remaining days it’s not dry – it feels slightly moist but not wet. The bottom of the pot is not wet either. What did I do wrong?
I had nursey plant my mandevilla in a pot with
a trellis. They wound several of the vines
around the trellis. The leaves at the bottom
look great and have flowers. However, the leaves at the top look limpy. Should I cut
the vines back to the area where the leaves look ok, or simply leave it as it is?
Purchased 4 giant crimson and white mandavillas at 3-3 1/2′ tall w/plenty vines. We created 3 – 2′x 2′ hand crafted wooden planters on our deck. Planters are about 20″ deep and lined with rubber roofing material, a drainage pvc piping from bottom of planters. Water should drain off back side of planter off deck. The 3 planters are connected by framed lattice for climbing. We placed Hydroton (explanded clay)inside planters with window screen on top. Will place soil and plant on top of this. Living 15 miles inland from Boston. Does this seem to be a proper system? We will receive plenty of sun. I’m anxious to transplant but concerned with the weather. It is only May 5. Also, how do I store the plants in the meantime? Keep outside overnight unless under 50 degrees?
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?
I live in San Antonio, TX. I purchased a Mandevilla last spring (2011). It is in a large container on my front porch. Since we had a very mild winter it made it through with flying colors. I bought a very large single trellis and keep wrapping the new growth around. It is almost four feet tall and everyone comments on how beautiful it is. I wanted to move it, but was told it does not like afternoon sun. Is this correct? Thank you for your reply.
Just returned from Florida vacation and my wife could not resist running out to get some sun parasol crimson mandevillas . I have a problem with deer ,Will the eat my new purchase
I want to keep my crimson mandevilla indoors. I have a large picture window but no direct sunlight. Would my plant survive indoors under these conditions?
My daughter brought me my first Crimson Mandevilla plant today, it is beautiful.I transplanted it into a larger pot, but the pot is not quite deep enough. At the top outside edges I mounded the sides up with good potting soil. Will this be ok.
I live in far west texas & thought the madevilla would be good to plant in the backyard so it would vine up on the fence for privacy (like my honesuckles do)…but all the comments I read see that this plant is in pots. Am I wishful thinking that this flowering beauty will survive hot summer sun & cold-ish winter (zone 8)?
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?).
Thanks for the response! we’ll check that out!
my scarlet mandevilla’s are in pots. we live in southern california in the coastal range. they are 5 years old. moved them a month ago to their morning sun position and began feeding and watering. new growth began very shortly thereafter.
now lots of strong new growth and the beginnings of flowers BUT all the older growth has yellowing veins and drop off. this is the reverse of Rachael’s problem.
one garden specialist said needs iron. the older guy says over watering. i slowed down the watering and the leaf yellowing got worse! should i give it my camelia food or repot or flush the pots? HELP!
The veins are green and rest of leave is yellow. i thought virus, but then decided to give it camellia food. seems to have helped. oh, and i also flushed the pots to get rid of some accumulated salts. the yellow leaves were actually part of the new growth. just yellow leaves immediately followed by strong new growth.
Slow growth on Mandevilla
I have always grown mandevilla very successfully in pots but in my new residences I wanted privacy and plant 5 plants to climb over a wrought iron terrace railing unfortunately they are very slow growing and not the normal lush amount of leaves.
Hi Caroline
Perhaps your mandevilla need some fertilizer or the soil is not condusive to good growth. They need well draining soil.
We purchased a mandevilla last spring and planted it in our back yard on our fence. We live in the high desert of Southern California zone 8B. It gets sun almost all day and did great thru the summer. We did not do anything to winterize the plant but had a pretty mild winter. The whole plant is brown, vine and leaves. It is just starting to warm up for spring with temps in the 60′s & 70′s. Did we kill our plant or is there a chance it may come back and we should wait a few more months? What is the best way to winterize when being left outside?
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?
Still nothing. It’s been 2 weeks since my previous post…
If my plant went dormant, how long will it stay dormant?
Thank you for your prompt reply. I have a wall of east facing windows. Will that do for light or would you suggest that I put it into this light and still prune it back in the spring?
Thank you agian.
Robin
I was recently given a potted mandevilla which had been stored in a cool unlit room. It has numerous green shoots ranging from a few inches to 3 feet and filled with lots of tiny buds. It was not cut back as suggested. What I do with it now that it has shoots? I do not have a sunny room to store it.
Thank you,
Robin
Aphids
I have a red Mandevilla that has some kind of growth on the new leaves and stems they are ayellow fuzzy type growth. They wash off but come right back the next week.
The plant was outside and we moved it inside for the winter.
We think that they might be insects.
Hi from Minnesota. I have a dipladenia that is wintering in my sunny sunroom when there is sun. It has developed white fuzzy bits that are on the branches, in the crooks and on either side of the leaves. The fuzz when removed has a pinkish moist interior. The plant otherwise seems to be doing well with normal dropping of leaves. Flowering has stopped. Vines are growing. What gives?
leaf drop in winter
I live in Ohio, so I winterized my mandeville vine as specified and brought it in the house. It looks dead. I did not over-water it, but the leaves are dried out. Did I kill it?
Grow from seed
I live in Fort Worth,Texas and I got some Mandevilla seeds from a neighbor. Can you tell me what is the best way to get them to germinate and when should I start germinating them if I would like to let them climb around my patio? I’m not sure if they will die over winter or not.
Shedding yellow leaves
Hi,
I live in Southern Ontario, Canada and purchased my first “Pretty Pink” Sun Parasol plant in June. I had it in a full sun location all summer and it grew and bloomed beautifully. I brought it in for the winter and put it in a sunny window. It was doing great and even bloomed for a couple more weeks but lately I have noticed the leaves are turning yellow pretty fast. What can I do so keep this wonderful plant from dying? It is still in the 12″ pot I purchased it in and I have been watering it once a week like I do my other plants. Is that too much or too little? Do I need to fertilize? What kind, how much and how often? It did not come with much information so any that you can offer would be a huge help.
Thank you in advance for responding!
Trim vine for winter
I live in Western Pennsylvania. I have a Giant Crimson Mandevilla – which has been beautiful since I got it in the spring. I understand it needs to come inside for the winter. My question is – should it be pruned back or left to grow as is? If it needs to be pruned, how much should be cut off. Thanks for you help
Hi! I’m a first timer with Mandevilla and I have 2 Sun Parasol Crimson red Mandevilla that I bought late spring and fell in love with these plants, both are doing great, healthy and still blooming. I live in northeastern New Jersey and have an unheated enclosed porched that allows morning sun in and that’s where I plan to keep my mandevillas for the winter. Do I have to keep them dormant or treat like houseplant. I have spikes and citrus plant that I kept in the porch during winter and so far managed to survive. Please, I need your advise on how I can take care of them during winter. The porch is really very cold during winter. Thank you very much!
I’d like to grow mine in the kitchen trellised up a wall. I understand the risks of rot and bugs, and am researching a good grow light to hang from the ceiling. I got advice that light would have to be very close and on the blue side to produce adequate growth for flowering. I’m in Santa Fe NM so i could cut back nd summer outside but would hope they could remain part of my kitchen design yearround. I could always rebuy each year, but I’m handy enough, any additional advice?
I’m thinking maintain new root cuttings away from inside plants, maybe start annually for growing season outside?
I appreciate all your wisdom shared in precious posts…very interesting!
Winterover mandevilla
I bought a small but beautiful Sun Parasol Crimson Mandevilla in late summer, full of blooms and vey healthy. I live in Nashville, TN (Zone 7) and know of course it would never survive one of our winters. I have a basement which would provide shelter but no guarantee of above-freezing temps. What about putting my Mandevilla in an unheated bedroom during the winter months but which does not have much sunlight? How much sunlight and at what temperature range does a Mandevilla require to successfully winterize it? Would love advice from anyone so I might enjoy this beautiful plant again next summer.
Cut back mandevilla
Can you tell me when and how far back I can trim our mandevilla. I was told that if you cut them back they would not bloom for a year. We live in Louisa Va. The plants are kept inside in the winter and out on the deck in the summer. We have had them for years but they are looking stringy because we don’t cut back anything but the dead ends.
Hi, I live in Scottsdale, Arizona. I have two red mendevilla plants in pots with well-drained soil & in outdoor shade (front porch). I have had them for about 5 months. They have been very healthy until recently starting to have the browned spots on leaves and wilting. I removed all the brown leaves, got more careful with watering and move both pots indoor with light through the glass because of the continuing excessive heat over 110 degree recently. Should I use the fungicide to treat the plants and also keep them indoor for sometime? Do I need to repot? Thanks!
Caterpillars on mandevilla
I have a beautiful Mandevilla plant growing in our front yard. I just noticed that there are these orange spiny catapillers eating the leaves. We live in Florida and it gets plenty of sun. How do I get rid of the catapillers?
Hello – I love reading the mandevilla stories. I have some questions.
I bought two mandevilla (white) this past summer. They repotted them for me at the nursery when I bought them and they are doing great. I can’t believe how often they flower and I am usually death to plants. Anyway, my questions are:
Will I need to repot them soon? How can I tell?
Would they prefer to be in a clay pot next time? They are in plastic now.
Will it hurt them if I trim their thin shoots that like to attach themselves to other things?
Thank you very much,
quick question!
I live in Washington state — just purchased 3 beautiful red Mandevillas in hanging baskets. Did not know they would need to be taken in for the winter. Is there a place to plant them near the house or something that i can leave them in the ground year-round?
Aphids
I have these aphids and water is not knocking them off. Is there a pesticide
that I can use to get rid of them permanently. I want to make sure, they are
actually moving on the vine. Is this what Aphids are? The plants are continuously
blooming. Please advise.
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
Soil ph
I removed all the yellowed leaves, mulch really well with an organic compost…still a little droopy on two of them…but they are putting out new leaves. I did check the ph and it was at about 6.5. I know this is a little high for them…I am hoping the compost will help…it is specific for mandevillias and palms. I am going to check ph in few more days…if it is still a little high…do you have any ideas for lowering the ph?
I planted a Mandevilla in between two evergreen shrubs and now they are staring to look a little sick. Is there a compatibility issue that you know of?
Aphids
I have a mandevilla in my patio and it constantly is getting little yellow aphids (bright yellow little bugs with black spikes)…within a day or two an entire branch is covered..I spray it with Neem Oil and they turn into black soot..but sure enough they reappear a few days later elsewhere–short of spraying them everyday which seems impossible because I tried and its not working.. do I either get rid of the gorgeous plant that is thriving and flowering beautifully or do I give up and let the aphids go at it until winter approaches. I live in Southern California.
I have three Mandevillas. They were all doing really good till this Monday. I left the water on in my pool over night by mistake and over filled the pool. It took it all day then next day to quit draining out into my yard. Within 24 hrs…two of my Mandevillas were wilted looking…just kinda droopy and by second day the other one started getting yellow leaves. I have not watered all week now…as I know they were way over watered. I am not seeing any improvement. I have wondered if that pool water ph was not good for them…or if it was just sitting in standing water for over 24 hrs.
I just purchased a Mandevilla. It is beautiful. Before I even plant it I want to make sure I do it “right”. I live in the Inland Northwest where it gets hot in the summer……cold in the winter. What is the best place to plant this…..southern exposure? Stay in the pot in came in or transplant to a bigger plant? Thanks.
Please help me this is my first time with mandevillas. I have two lovely plants in separate containers on my front porch which is sunny in the morning hours. At the beginning they were growing beautiful with healthy looking leaves and dark pink flowers. I water then every day and fertilize then every other week. Suddenly, the flowers on one of the plants turned very light almost white, then the buds were brown at the tips and they all fell, now the leaves are turning yellow and the other plant is getting brown spots. I am worried. What should I do? I live in the New York area.
Thank you
I live in west texas (zone7) Can I plant Mandevilla outside.
Hi!
I have two identical mandevillas potted on my front porch. They get direct sunlight most of the day. The plants are very bushy but the leaves are starting to turn brown from the middle of the plant. The brown leaves have spread to the outer leaves and the plant looks to be dying. The other plant is just starting to turn brown from the inside also. I’ve had mandevillas for years and never experienced this problem. Can I save the healthier one?
Thanks!
I live in Long Island, New York and have a couple of Giant Pink Mandevilla planted in pots climbing the front columns of my house. They have been there for about 2 months and doing nicely. Whenever they are watered the water is quickly absorbed into the soil.
Yesterday – in the midst of this heat wave no less – I noticed one of the plants was very wet, puddling in the soil, which was odd because )a of the heat wave and b) it had not been watered since the day before and c) all the other plants around it were dry. This morning – same thing. The soil is mysteriously very damp.
I am baffled, and hope this is not the beginning of the end for this plant, like drowning in its own… whatever.
I did add some soil to the pot which has seemed to stav the ‘wetness’ but the plant is looking rather sad.
Thank you in advance for your comments and suggestions.
Yellow new growth
Great website! I live in the desert. I have one potted mandevilla which I placed in my garden under a pergola last winter. It bloomed profusely and thrived through a freeze (which killed some bouganvilla) Now it’s not blooming at all~We’ve had several days well over 110~ It’s healthy otherwise, and climbing well~Have been feeding a blooming fertilizer every couple of weeks, and watering daily. The other 2 which I planted in the ground get the same care but are yellow on all the top leaves. They get some filtered sun & mostly shade during the day, and have not bloomed at all this summer. Too hot? Thank you!!
Heat stress
My Mandevilla, is in a large planter, w/soil – think it’s Miracle Grow – that retains the moisture & isn’t supposed to allow the plant to absorb TOO much water. The leaves are turning yellow. We live in Texas, the plant is on the front porch, which faces West, and the temperature gets quite hot in the afternoon, what temperature & prolonged exposure, is too much. Additionally, the front porch is essentially a brick oven – bricks on house & slab of porch…..(I didn’t design this place…). Could the yellow leaves be from TOO much water? Or TOO LITTLE? Not enough fertilizer? I just checked the pot, and the soil is quite dry on top.
I live in Waco, Tx and the temperature is 100-102 degrees right now. My mandevillas leaves are turning yellow/brown. I water them every/every other day. One of them gets morning sun; the other one gets afternoon sun. What do you think might be the problem?
Help!!
why can I not get my Mandevilla to bloom? It is is mostly all sun in a nice big pot and fertilized once every two weeks or so. It looks healthy just no blooms.
yes I am fertilizing about every week and a half with 10-10-10.
Try using a high phosphorus fertilizer (10-20-10) or a bloom boost every 2 weeks.
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!
Virus?
So glad I found this site, have a problem no one has mentioned. This is my third year with previously beautiful, flourishing pink Mandevillas that grew up the sides of the porch and even across the top, making a beautiful, tropical display.
This year, all the new leaves at the top are coming our very small and disfigured, mottled ends, some with out much of anything on one side of the leaf. Growth is sparse also. Fertilized regularly with Miracle Grow and Bloom Booster, as we did in years past. Did use one dose of Superthrive, which says it is vitamins and hormones??? I took it to the local botanical gardens and they thought they saw a few spider mites spots, but there are no webs or bugs to be seen. I sprayed both of them with purchased insectide soap, but have this sick feeling, there is more to it, that that. Oh, how I hope you can shed some light on this. Thanks in advance.
Hi Judie
Are they growing in the ground or pot? If in a pot did you replant in fresh soil this year.
Hi there,
Yes, they are in the same pots as last year, when they did so beautifully. I did use new Fertilome soil, that even says good for tropicals. I washed both of them with purchased insecticidal soap. Wondering now if I should look for Neem Oil. Still getting some blooms, but not as many as before. One at least is climbing with it’s little leaves, the other is definitely lagging behind and it seems the older, established, larger leaves are disappearing. I am mystified….and bummed. : o /
I have two beautiful Mandevilla planted in large pots. They get direct sun in the afternoon and both are blooming profusely, but they’re not climbing! I’m so disappointed; I have beautiful trellises in the pots to train them. Is there a trick to get them to climb? The only thing I can think of is that they went from small pots at the nursery to my very large pots, and the roots are growing but the plant is not. Is that right?
I have a madivilla I planted from a nursery at the beginning of June. Located in NW WI. The plant looks great and is growing well. Have had hot weather an plenty of rain. It is not blooming. I’ve used some fertilizer on it, but still no blooms. It is planted in a nice big pot. How do I get it to bloom?
Thanks
Hi Joan
Is it in full sun?
Yes it is in full sun during afternoon. In the morning until about 11:00 it is in the shade
I have read that Mandavilla is hardy to zone 9, but then I read that it needs to be inside when the temp dips below 50F at night. I see zone 9 temps are down to as low as 20F at night. Will I have to take my new Mandevilla in for the winter in San Mateo CA which is solid zone 10, down to 30F at night?
I have several Mandevilla plants. One has dark green leaves 6-7 inches long, others have much smaller leaves and do not vine like the one with big leaves. The large leafed one seems to be much more vigorous than the smaller leafed ones. What is the difference in the plants? Do I need to care for them differently?
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.
I purchased two 4 foot potted plants in May. Both plants blooming. One dropped all flowers and shows no signs of returning blooms. They live on the patio near each other, same environment. Will blooms return? Anythink I can do to coax them back?
THX!
Some stressful condition caused the plant to drop its blooms. Is it possible that the plant is pot bound and dries out quickly?

1 of 2 mandevilla plants is slowly dying; leaf drop, spotting, curling. One bloom on the way. I water the plants once every two days or so. they both get full sun. the soil is rich and has a few inches of stone on the bottom of the pot for positive drainage. I have dilluted some fertilizer in water (slightly less than asked for on the directions) and applied the mix to the plants 3 weeks ago.
the strong plant has been getting more leaves and deepens in healthy green color. My first bloom is on the way. I have had them in pots now for almost 6 weeks.
the weather has ranged from 70 to 90 degrees with evening thunder showers every few days.
hi… I am a new mandevilla owner.I live in central Minnesota,and we are having an unusually long period of rain and cool weather. Is this going to hurt my plant ?
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?
I purchased 2 of these plants and love them. One plant shriveled and died all of a sudden. Now the other one is starting to do the same thing. Turning brown from the vine up. Inbetween time, I purchased 2 more and don’t want them to die too. I live in Kansas, 80-100 degrees and wind. They are on my deck which is covered by a huge maple tree but still get 1/2 day sunlight. I don’t think we’re under or over watering & the pot has drainage. Any ideas what I might be doing wrong?
I Just purchased two of these beautiful Mandavilla plants. Do these climb? should I plant in the ground or pots? What other plant’s look good with them?
Ok, now my Mandavilla vine has turned totally brown and I think It’s about dead. Can I cut it way down and hope that is will come back? There is really no reason for the dying leaves it’s been watered, not too much, I’ve been taking care of it. Is it a lost cause?
I am having a terrible time with Mandevilla plant in just one pot this summer. It is just wilting and dying. I have checked the soil and it is not too wet and I also have other plants growing in the same pot. This is a very large pot that has a match on the other size in a pool area, the other Mandevilla is thriving but cannot keep one alive in this pot. There are no browning or yellowing of the leaves just one day I walk out and the plant is wilted. This is the 3rd plant in this pot and each one has had the same problem. Lost as to why?
Ants in plant
We discovered our mandevilla (potted) was infested with ants – not the leaves or flowers but all throughout the dirt and roots. We applied insecticide and replaced half the dirt. Our girl is still turning yellow – from the bottom up – but she still has new growth on top. Is there any hope for our gilr?
Leaf drop
Hi-
I have always had luck with Mandevilla before, but this year is different-
Its been a wet, cool summer so far, and my Mandevilla seems to be in trouble. I am trying to keep it from getting too wet, but the vines seem to be turning brown and dying off, and the leaves just drop off. They aren’t yellowed or browned- they look to be perfectly healty leaves until they drop. Any ideas for what to do or what might be wrong? Thanks!
Hi! I recently planted red Mandevillas around my salt water pool in northern Ohio. Now that the kids are swimming more, certain plants are getting splashed with the pool water. The red flowers on these plants are turning pink and even white in some places. Is the salt in the water affecting the alkalinity of the soil? I want my red blooms back!
I just purchased a mandevilla plant and it looks like it’s wilting. I have watered it because we have had day temps in the upper 90′s. Is it to hot for my palnt?
Poisonous
Is this plant poisonus to animals?

I live in Naples Fl. Temps daily are in the high 90s. My 2 mandevilla plants are in pots (2nd year for both). The pots are in all day sunlight, and we are not in rainy season. Curremtly I am getting a lot of yellow leaves. Could I be overwatering? Underwatering?
Thanks
