Winterize Mandevilla
Tips on how to preserve Mandevilla through the winter months.
Mandevilla (Dipladena) are tropical vines, hardy (depending on cultivars) in zones 9-11. They tolerate a minimum temperature of 45-50 F at which time growth will begin to slow down. In colder regions it is usually grown as an annual but can be saved indoors for the next season. For winter storage keep the plant outside as long as possible before bringing it indoors. Check the plants for insects and spray with insecticidal soap if needed.
Two ways to winter over Mandevilla
1. Houseplant
Treat it as a houseplant. Mandevilla can be trimmed to make it more manageable indoors and it needs a bright, sunny window to flourish through the winter. You will get some yellowing and leaf drop due to lower light and humidity. Water once a week, keeping it on the dry side. Don’t fertilize in the winter. In spring, when you see new growth, increase watering and start to fertilize.
2. Dormant stage
Another way to winterize mandevilla is in a dormant stage by storing it in a garage or cool basement with temperatures around 45-55F. Cut it back to about 12 inches above the soil line and treat for insects if needed. Keep it dry but not completely dry. Check periodically for soil moisture. Mandevilla will eventually drop all its leaves. The important thing is that you want to keep it alive through the winter.
In early spring, prune back any spindly winter growth and if pot bound repot in fresh soil. When new shoots begin to grow, fertilize lightly and move the plant to a sunny window. Pinch the new growth to get a bushier plant. Set it outside when danger of frost has passed or night temperatures are above 55.
Leaf spot disease
Hi, I am new to gardening, and I live in Illinois. I don’t know exactly what zone I’m in, but what would be the best way to winter my mandevilla bushes? And also, my mandevilla have been growing great all summer long, but recently all the leaves are starting to turn yellow, and some have tiny brown spots, and the flowers have fallen off. what is happening to them, and is there something I can do. The temperature has been about 100 degrees lately. Please help me out. Thanks
I just purchased my first Crimson Mandevilla from Lowes, and I was NOT told that it is a annual, I planted this beautiful plant this August, and I have wonderful results. It is climbing up the trellis, just like I wanted it to. Now that winter is coming fast, I looked up this web site and discovered that I should NOT have planted this wonderful plant.
I live in NJ which is in zone 6, and I am hoping that I do not have to dig up this thing of beauty, and possibly destroy it!! 🙁 If I cover it, mulch it, and cut it back, will it survive our winters? As you can see–I am totally new to growing plants. and any help would be appreciated
I have several Mandevilla’s 2 of them developed spots on the leaves,they turn yellow, some of the leaves look like they are burned and they fall off. I dont know if I have Spidermite or some other disease, can you help me.
Thanks.
Hi 🙂
My Mandevilla has what appears to be spider mites or some type of pest that is bright yellow & appearing on the stems of it. I seen where you suggested to use a strong spray of water but I was wondering if there is a pesticide I can use for tropical to stop them from coming back. I live in Ohio & will soon be bringing all of my tropicals in for the winter & I don’t want the rest of them to get these on them. Any & all suggetions will be appreciated!
I once saw a clippings w/ root of the mandevillas sitting in water at a greenhouse, when i tried that at home it did not happen for me, they just died. Will root clippings survive to be replanted? What was the greenhouse doing? THanks, ERika
I have 2 Mndevillas planted on either side of my driveway. was told they would vine along the fence. As yet they haven’t vined. One blooms nicely but the other one seems to look the same as the day it was planted. I used
Miracle Grow Bloom Burst. I live in the Pittsburgh PA area where this summer has been terribly humid. Is it necessary to “pot them” and bring them in for the winter or is there some way I can prepare them for the cold of winter?
To repot or not
Thanks for all the wonderfully concise information! I just picked up two mandevilla for half price at a local greenhouse. I live in the Chicago NW Suburbs, so I will overwinter the plants.
It’s the last weekend of July. Should I leave the plants in the pots in which they were purchased, or put them in new, larger pots?
The “Tango Twirl” (Monrey) is in a 1 gallon pot, with a 2′ bamboo teepee.
The “Sun Parasol” (Sunparacoho) is in a smaller 8″ pot, with two visible plugs. Would it be advisable to divide it now, or wait until Spring? If I am to divide them, what size pot should I use?
Thanks For your advice!
I recently received a mandavila plant. I live in the akron ohio area. My first question is if i plant this in the ground to have it climb on a trelis do i need to dig it up in the winter months so i can have it in the spring. Or do i just leave it in the pot for the summer and fall, cut it back in the winter and then put it back outside in the spring…not really clear on this..thank you
It’s easier to leave it in the pot so you don’t have to dig it up in the fall.
What a wonderful website! And my first-ever Mandevilla is the best flowering porch plant I’ve ever had! I’ve spent an hour reading all the Mandevilla posts, and have learned so much. I live in a second floor apt, and our screened-in porches are wood lattice work up to about 4′ high. The plant is twining in the lattice work (with gentle nudges from me), and blooming beautifully. It’s still in the plastic pot I bought it in, and I water it every morning, twice a day when it’s over 90. I’m in Indianapolis and we have hot, humid summers & cold winters. I was concerned about the yellowing leaves, but having read these posts, I see that is normal. I plan to over-winter it indoors in a dormant state, then re-pot it and enjoy it again next year. I also plan to buy two more next spring!
Thank you so much for your excellent growing advice and for this wonderful website!
Thanks for the comment! Glad I could help.
Are the tubers on my Mandevilla roots root rot? If so, can the plants be saved? Will they infect a healthy plant if I plant a new plant in the same pot as my infected plant? I live close to the beach in central California. We get a lot of fog. The plants are in plastic pots on a west facing deck. They were getting yellow leaves and not doing very well so I decided to repot them.
I live in Southern California, I just found your site and never knew how to proporly care for my Mandevilla. I water it about twice a week when the soil drys out. During winter, I did not take it in and now it seems to be loosing a lot of leaves branches are getting bare but still has flowers. I just put it in a larger pot. Is there anything else I can do to save my plant.
I have taken my 2 mandevilla plants to florida with me.I live in NY in the summer,they have done nicely all winter.I have not had any flowers on them since i came down in oct .I also now see one of them has some black on there leaves.What can I do to save them? I have grown them since they were about 2 ft.
Hi Sue
Do the leaves have black spots or a black film on the surface?
yes they have black spots on the under side of the leaves. they also have not flowered all winter
I have two Mandevilla that I am overwintering together in a sunny window. The red one was overwintered last year as well but took a long time to bloom this summer. It is looking very good with nice green leaves and signs of new growth. The pink one was new last summer and it has lost a lot more leaves but has more new vining growth (of the straggly variety). I understand it may be time to start with some light fertilizer and trim back some old growth. Do they need different types of care (i.e.different fertilizer) since they are in such different conditions? And how soon is it advisable to start fertilizing to encourage quicker blooming? And since they need growth before they can bloom – is a 10-10-10 fertilizer best? At what point should I switch to the higher phospherous fertilizer for blooms? I live in Northeast Nebraska (zone 4) and am planning to start putting them outside on warmer days to acclimate them to the outdoors.
Thanks for your advice!
Winterover mandevilla
Hi, and Happy After New Year’s.
I followed your instructions and put my mandevilla in the garage when the temperatures first started dropping last fall. She actually bloomed into the winter — in the cold garage. I eventually brought her in the house and set her up in an East-facing bathroom window. She’s dropped some leaves, but is now getting new green shoots (on old wood, I didn’t trim her yet), and she has some very small green-dot-sized growths at the base of the stem. I’ve read your posts and I’m not sure if I should start feeding her yet. She’s been drinking lots of water (a good drink every 6-10 days), but I’ve not fed her yet. Also, did I get it right? I should trim her soon … but when? Thanks for any help you can offer. By the way, we live in Maryland. Thanks for all the info you post on this site.
So appreciate all the good dependable info you share. I have a variety that is unusual and i love it and want to keep it ..can’t afford to replace, lost one of my 4 but not the 2 special doubles that are spectacular. Will follow directions carefully to keep them healthy. Thank you and keep up the fantastic work!
Winter survival
I live in northern Michigan. My boyfriend bought me a beautiful Mandevilla in a hanging basket. This is the second winter I’ve brought it inside. Both years many (but not all) of the leaves turned yellow and dropped, and it produces long off-shoot vines (which does not happen in the summer). It looks pretty sad – not a very nice-looking house plant. However, last summer it did well when I returned it outside. What can I do make the plant happier and nicer-looking during the winter months? I do keep it pretty cold in my house (57 degrees) when I’m not here (which is often). When I am home I only heat to 64-67 degrees. It hangs in a nice bright spot (indirect light) and I water weekly. Also, should I keep or trim the off-shoot vines? It made the plant look so scraggly last year I trimmed them.
I live in South Florida and my mandivillas have stopped growing and have shed their leaves. Should I prune them and set them aside for the winter months?
Please help. These plants were beautiful.
Hi –
I live in central Michigan. My mother purchased this plant for me this summer and I kept it outside in patial sun. Was gorgeous all summer and fall, the vines even attached to my lattice! As it got colder, I trimmed the vines from the lattice and brought it inside. I am wondering if I should put it in a larger pot and add some bamboo trellis for it? It is about 20″ tall and still looks great, should I prune it?
We purchased some large Mandevilla plants last spring which flourished until the weather turned cold here outside Boston. I would like to overwinter them but have very little room for them where it’s sunny in our house. They spent the season in the large (maybe 7-8 gallon?) pots we bought them in and the roots now pack their containers. How will they fare if I cut the root balls back to, say, 2 or 3 gallon size (in addition to pruning back the stems as you have advised others) in order to be able to manage them overwinter in the house?
Thank you for all you informative answers on this site!
I live in Southern California and our Mandevilla was thriving all summer then about a few weeks ago the leaves started to turn yellow from the bottom up and wilting. From reading all your great answers it appears I may be overwatering? I water it every 4 days or so and it has a saucer. I recently started fertilizing, but is this the resting period even here? We love this plant and want it to survive. What do you suggest?
Winterover mandevilla
Loving this site. Have learned a lot; unfortunately just today and I may be too late! I am in Massachusetts and I have two Mandevillas of different types (not sure what types tho) and we got a heavy freeze last night. I did cover them, and they’re definitely still a live, but I’m not sure for how long. I decided to bring them in this morning and I need to cut them down (both really big) and since I don’t have anywhere in my house to put them (only one south facing window and all my regular houseplants are in it), I’m thinking I should try to overwinter in the basement. Temp usually runs in the upper 50’s to low 60’s (we have a kitty) down there and somewhat humid at times (constantly run a de-humidifier). Do you think I can box them up and keep them that way? Should I wait ’til the leaves drop? Should I fertilize at this point or just water a bit, pack ’em up and check them/ water them montly as previously stated? Thanks so much!
I live in Phoenix, AZ. where summer temp’s reach 110F in the summer. Can the Mandavilla take that kind of heat even if it is in the shade?
Yellow leavesI live in the Orlando area and planted my mandevilla this spring. It has been doing beautifully, but all of a sudden it started turning yellow and looking like it is dying. All my other flowers and plants in the same bed look great. Have I done something to kill it. How can I tell if it is still alive or just going dormant. It has started cooling off in evenings and we have had some nights in the 50s.
I live in NH and purchased a Pink blooming Mandevilla plant this summer. I took my plant indoors when temps dropped below 40, I have it in our living room near a window, which is always around 50-55 degrees, there are no leaves left or flowers, I water it occassionally when it starts feeling dry? Will my plant survive the winter inside?
Grow lights
Hello,
Well, I guess you could say I am on a “Save the tropics” mission. I live in southern NJ (zone 6) I have 2 mandevilla and 1 night blooming jasmine. All in pots and growing beautifully. Just brought them indoors. I have placed them in our garden tub, which is never used (to keep them away from cats). There is a skylight above the tub, but I am sure they will require some sort of grow light. Can you suggest a type or wattage of a grow light which might help them remain thru the winter indoors? I have read about so many different types…I am totally baffled! And is it possible for them to remain in bloom during our winter months, indoors with an artificial growing light? Or am I just wishful thinking? Your input is greatly appreciated. Thanks.
Thaanks for your reply
Hi,
Ive read many of the mandevilla posts and have a few questions – I live in Chicago and want to bring my 2 plants inside. When you say to prune them to half the size, is there anywhere on the plant I should cut in particular? I also don’t know what you mean when you say 10-20-10 for fertilizer. I am obviously a novice gardener! Thanks.
Thanks for the tip about buying mandevillas now.
I’ll check around this weekend.
Where can I find a mandevilla?
Thanks again. We have had intermittant deluges of rain mixed with drought this summer. So, it has been rather difficult to maintain healthy plants. But I will definitely use nitrogen on my mandevillas. Is it safe to use nitrogen on my other landscape plants, as well?
Hi,
I’m back. I found your website last year, and managed to begin overwintering two mandevilla(s?). One died during the winter, and the other survived, and actually made it back outside in the spring. Then it slowly croaked. I now have a beautiful rambunctious pink one that is happily growing all over the place. So, if I’m reading these posts correctly, I should be feeding her 10-10-10 now (or am I still at the higher middle number now?. I should detangle and disengage her before the first frost, give her a good washup, and a trim (she has long vines), and then spray for bugs before bringing her in. I can (possibly) try to root some of the trimmings. Then I should put this one in front of the sunny East window where the plants thrived last year. By the way, I live in Maryland. Did I get it straight? Please advise. Sincere thanks for your help.
Yellow bottom leaves
I live outside New Orleans and have enjoyed my mandavilla vines and hanging baskets all Summer. The leaves on my mandavilla trellis (which faces the south)are beginning to yellow from the bottom up. Could I be overwatering the plant? I fear losing this beautiful focal point! Thanks much!
I have this mandaville vine that we planted in a big 5 gal planterit was looking so good with beautiful blooms and green leaves untill about a week or so iadded some miracle grow shake N feed i beleive npk 10 10 10 since the tempatures have been in the high 90 or hotter ever day i have tried to water in the morning and evening but now the plant looks like it is dying leaves turning dark brown and falling off but some of the tips of flower looks like new growth we live in the deep south sure hope i didnt kill it thanks ed if you can help someone who has no geen thumb
Can I build a pink/blue/green 2inch insulation material case to store in my garage workshop to keep the 1/2 pruned sized plants in cool, dark, place. Your site says they wont die or grow if I keep them moist. What suggestions for heat source (lamps,heaters) to keep them over the 45 degree min temp Then when nite temp over 55 take them out and start fertilizers with 10-20-10. I need ideas for the storage case or box to try the experiment in London Ontario. Thanks
Can i divide my mandavilla into 2 plants?
Hi Jessi
Mandevilla can be divided. It should be done when the plant is dormant or not actively growing.
Not blooming
I have two beautiful mandivilla plants that are in large pots on my deck. These plants had flowers when planted but now I have no flowers. The plant is growing nicely and generating vines. I have fertilized the plants with a slow release fertilizer. but no buds are being generated. How can I get the plants to generate flowers? The plants I had last year were fine and they were located in the same location . .
We live in northern New Jersey. Thanks for any help you can provide.
I have a Question..i live in Victoria B.C. canada and I was wondering if I can plant my Mandeille vine deep in the ground and in the winter put lots of hay and grass clipping around it will is make it though the winter? our temp goes down to -6 for maybe a week at the most.Please get back to me ASAP thanks. Kari
Light exposure
I just bought a new mandevilla cause the first one died instantly and I want so much for this one to survive and grow I live in San Antonio, Texas could you give me some key points on how to care for this plant and where would be a good spot for it. On one side of my house is pretty much direct sun and the other has lots of shade which would be the best for it?
Mandevilla or dipladenia
I live in Fair Oaks Ca and just bought 2 trellised bright red flowering “dipladenia” vines. I googled and now am wondering if I have a “mandevilla” or are they one in the same. Is my location going to require overwintering or just mulched & blanketed for the occasional frost; and, what about our sometimes heavy rains in the winter?; it can get quite hot in the summer, so what light exposure will be best for this location? I believe I am in zone 9??
thank you.
Poisonous
I have a puppy that loves to eat my mandevilla flowers or leaves. I cannot find out if mandeville is poision to them. I cannot seem to break this habit no matter where I put my plant he seems to be attracted to it.
Mandevilla from cuttings
I live in SW Florida, just outside Ft Myers (inland) to be exact. I have 5 Mandevilla that are inground. I covered them this past winter when the temperature dropped to 27 for a couple of nights. They survived and I have been trying to root cuttings from the different colors I have with no success. I take a cutting about 6 to 8 inches long from the new growth, use a root stimulate and place in peat pots in my garage under grow lights. After about 2 weeks the cuttings start to turn brown at the base while the tops remain green. I keep the potting soil moist. The outside temps range from 70 to 90’s this time of year while the garage is much hotter. What am I doing wrong?
So glad i found this site. I just got my mandevilla today, i live in Ohio, so from what i have read so far, i should leave it in its pot and bring it in on cold nights, and thru the fall winter ( i def. want to keep this one, fell in love with it when i seen it) I have a large picture window that i can put in front of during the fall winter months and during the spring days i will take outside, and just bring in during the night. is this all ok to do?
Winter hardiness
i live in kansas city ,mo i just bought a mandevilla .will it survive the winter here
Mandevilla care
Wow, I am so glad I looked this plant up online and found this website. I live in PA, just brought a pink/red mandevilla and was going to put it in the ground tomorrow. Is it better to leave it in the container it came in, transfer to a bigger one, or can it be planted in the ground? Also,the area i brought it for, is primary shade, is that a bad idea?
I appreciate your input………..Thanks
I overwintered two Mandevillas (dormant in a cool basement). In March, I brought them upstairs to warm them, gave them some water and put them near a sunny window. The pink Mandevilla is slowly sprouting new leaves from its old stems. The red Mandevilla started to send out tiny little shoots around the center stem near the base (these did not grow along its old stems like the other Mandevilla). Then all the tiny, little green shoots disappeared on the Red Mandevilla, withered away. Now, all I have are brown stems left over from last Fall. I tried scratching at the stems and they show no green, the end pieces just snap like dead wood. If the roots still have some life, is there anything I can do to get this red Mandevilla to resurrect? If I recall, the red Mandevilla didn’t need full sun. Maybe it’s getting too much sun? I now have them outside on 60 -80 degree days.
Fertilize mandevilla
I am going on my fifth season with a red flowering mandeville in the Boston area. It was very pot bound and desperately needed re-potting. I was told to cut the roots back to the main root, prune back the top growth, which was spotty by now, and fertilize. I found it had several large tuber type roots growing on the sides and bottom- which I left intact. It is re-situated in a larger pot and moved to a glass paned screen porch for the spring and will go outside in May. I thought with all the pruning and root reduction that it should rest before I fertilized it so I did not fertilize – do you recommend that I do? If so, what type?
I have three other younger mandevilles, whites and pink- I am amazed at the amount of neglect this plant will tolerate and still bloom each summer. It even attracts hummingbirds!
I’m so glad I found this site.
Hi I appreciate your help I got last Sept 09 on my new mandevilla. I live in Colo; I stored in soil in a plastic container with lid on it. Also tried to moisturize it every month. When should I slowly get it acquainted with the outdoors? We’ve had a late winter, in fact just got up to foot a snow in drifts last week but melted it fast in a day. Thanks for your help! Happy Easter & Spring!
Thanks for the advice, I will get them out as soon as it warms up. This is a wonderful site , so helpful!
Hello, so excited that I had found this website its so full of great info and has been a great help to me. I purchased my plants in summer and had beautiful blooms all summer into fall. I brought them in during fall and began to winterize them. This site helped me winterize and learn so much. I placed them in my house in full sun all winter and checked them daily. I would water them when they looked dry and a lot of leaves dropped. In early spring I would begin to mist them w/ water. They are producing long strands of new greens and others with dark green leaves, seems very healthy . Im guessing they survived the winter and I did it all correctly! I live in PA, can you tell me if its time to start fertilizing them yet? When it warms up even more do I begin to take them out little by little and return them back to the house until it gets warmer? Thanks sooooo much for the advice, its been a great learning experience so far!!!!
Linty hairs on leaves
I live in Madison, WI and am overwintering my mandevilla for the 2nd year. I’ve noticed both years that there’s a linty-looking fuzz on the new leaves when they form. I don’t see any bugs, but is that what is making this linty looking fuzz? The plant doesn’t seem to be harmed but I don’t want insects getting on my other plants either. The plant is producing long tendrils of growth and still flowering. Should I leave well enough alone or spray something on it?
hi, we live in southern california (los Angeles County area) and bought our Mandevilla plants(2)during the summer at home depot and the were already well established. we placed them out side in our patio where its lattice covered, but still gets a fair amount of sun. we bought “miracle grow bloom booster” we used it every 2 weeks and watered until water drained (but not flushing it) out of the pots, we watered every other day during the summer, and during fall/winter watered about every 2-3 days. but i noticed during the fall the one looked like it was dying and by the winter looks dead the other stared to brown and looks bare im afraid that one is dying also. what can i do to bring them back? is the one that looks dead still savable? ( im still watering it and giving in the miracle grow) i hope they just look that way cause that what they do annually… i need help! i would hate to loose them:0( please help, i would do anything to bring them back
Mandevilla seeds
I have read all the questions on your site and did not see anything on a spiky two or three pronged growth of about 8″ on Mandevillas. I took my plants inside for the winter . Are these seed pods? Should I cut them off or
leave them alone?
Help. I brought my Mandevilla vine in the house for the winter and today noticed that there are tiny yellowish bugs all along the vines. What are they and how do I get rid of them. Thanks.
Hi Sally
I’m not sure what type of bug you have. I need more info. Are they oval shaped and bunched up in clusters? Are they soft bodied that can be squished? Could be aphids.
Are they round or oval bumps that need to be scraped off? Could be scale
I have left my plant out and it has been through several heavy frosts….looks dead. If I dig up the tuberous looking roots, can I plant them in a pot in the garage over the winter? Will it grow and bloom again next Spring?
I’m about to feed my mandevilla before bringing it in for the winter, and will keep it in a sunny spot, not letting it go dormant. But I’m confused about which food to use when. I have some 10-54-10 and a more balanced food which is 10-10-10. Which food is better for winterizing, and which is better for new growth and lots of blooms next summer?
Thanks for all of the info! We live in Richmond, Va and I gave my mother a Sun Parasol Crimson Mandevilla (Sunmandecrim is part of the discription). We plan to bring it inside as suggested above, etc. BUT the plant’s info /care instruction tag says this is an annual. Does that mean we bought an Annual version of the plant OR is that just becuase it is a tropical plant and not expected to come back unless it is brought in. We will be extremely dissapointed if this variety is actually an Annual and cannot be saved. Do you know?
I have a mandevilla and it is not doing too well. I live in Louisiana, I have it outside partly shady and it is spiraling up my porch rails. It usually doesn’t get too cold around here till January. It still is just growth, no blooms. I have fertilized it with miracle grow several times and still nothing. What should I do to help it grow and stay alive during the winter. I don’t have a green thumb, but it was one of my mother’s favorite plants before she died so this year I decided to buy me one, but I just can’t seem to keep it blooming or growing for that matter. Thanks for your time.
I’ve been reading your replies with much interest. What are my chances of saving an in-ground Mandevilla in Oklahoma City? We usually have a mild winter, but will get at least 2 bad blasts after New Year’s. And I read in one of your replies that these bloom on old wood, so could I take this year’s vines, and either mulch and/or cover with a large bell jar after I mulch the roots? Not to leave the glass on all winter, but intermittently, when the weather goes sour? Or will the one or 2 blasts be enough to snuff this plant? Thank you!
Unwanted spindly winter growth & slow to bloom
I have a mandevilla that I winterized last winter and it’s healthy except that it did not bloom for me this summer and it also took all summer for it to grow. I fertilized but still no blooms. I bought a baby plant in the spring and that one took off beautifully.
So, now I need to winterize both plants to a “dormant stage”,but while the plant was in so call dormant stage it developed pale new growth. The weather was still not ready for outdoor exposure. Can you give some tips on how to deal with that issue if it happens again? By the way love this site!
I have a mandevilla that’s new to me & it has new growth at the bottom but the top is turning brown. Should I cut it back or wait? I have given it Miracle Grow & pest ridden it when I brought it in for winter. It didn’t bloom for me either this summer.Thanks for your help.
Hello,
I have read all the entries of this post, and I thank youvery much for the clear, precise information. I live in southern central Maryland. We were forecast to hit the 40s – 30s last night, so I btought in my two mandevillas. One is in a pot, so I understand what to do. I dug the other one up, and brought it in. My question is what type of soil should I use for the one that was in the ground? It gave beautiful red blooms all spring/summer, but never vinde. It has plush low growth. I’d love for it to survive the winter indoors. They will both live upstairs next to an East window. Thanks for any help you can offer.
Hi,
I live in Ontario Canada and bought 2 beautiful plants this summer. I have just brought them inside and wrapped them in plastic bag ( dry cleaner plastic film) I have been reading your site and you talk of treating for insects.. A friend told me to wrap in plastic and spray for bugs and leave bag on for a few days. Is this correct procedure for Mandevilla plants? What do I spray for insect? The plants are thriving and in full bloom again. I can leave them in sunny location so do I need to trim them back?
I live in Fort Wayne, IN. We have very very cold winters. I want to make sure that if I put my plants in the garage over the winter since I do not have room in my house for all of them. Do I need to prune them down 1/2 the size or to what? Also since I would like to keep them in the garage do I need to cover them? Do I need to do anything with the soil? Then how often in the winter should I water them?
I brought my potted Mandevilla’s in lastnight to protect them from an early frost. We had a few house flies and a WASP flying around the room by morning. I had planned to leave them inside for the winter. What’s going on?
Hello, I live in Michigan and it snowed today. I thought I was resigned to my mandevilla dying in the winter, but when I looked outside to see snow and my plant looking wilted I freaked and brought it inside. The leaves are still green and the flowers were doing ok till today when it snowed. Now all the flowers and buds are hanging, the loose vines look wilted and the leaves on them are dead, but the leaves on the main plant are still green. My mom says the whole thing is probably dead and just not showing it yet. Is there a way to know if the roots survived?

I live in Southern California, Beaumont Calif.. I just bought two Mandevilla Giant White plants. I want to plant them outside, to vine on the block wall.
It does rain here, and some nights get cold. It gets hot in the summer, full sun where I want to plant them. Will they survive, do I have to
bring them inside in winter, when it rains hard or gets cold at night?
I live in Ind “burrr” clueless, I planted my flower in the ground I will mulch heavy at the roots but should I prune it back before the first freeze? It is just a baby and started flowering in May, my husband weed whacked it and some of it died and some survived, doing ok for now. Thanks
My children bought me a mandevilla in June 2009 for my birthday. I live in CO & its Oct. do I wait until all the leaves drop before bringing it in? The weather says its supposed to freeze tomorrow night. Also can I wrap the roots in newspaper & store them in a box or plastic box in basement? I can’t get the plant and container into the basement. Thanks so much
Pruning Mandevilla
I have a Mandaville and I was wondering if it could be cut in half, it is so big there is no way it will live in my house and I don’t want to kill it. It has wrapped it self and the trelis and I also have stakes in the with it and it has wrapped it self around those also, but I dont’ want to kill it and I am afraid if I cut it back that is what I will do. HELP
I have just read every one of your questions and your answers. This one I did not see. I live in the NorthEast Georgia area. Zone 8 I believe. My 3 Mandevillas are on the top of a small hill outside the pool. the chain link is what they grow on. I water every day. It has good drainage and they are so pretty they dont even look real. I have the thicker leaf type. We have a harbor near the vines with several electric plugs. I just got 3 clip-on heat lamps with the heat bulbs that will clip on to the top of my fence shooting down on each vine. Can I mulch as you suggested, cut back the vine and cover with plastic at night with the heat lamps shooting down every night and only take plastic off when the sun gets to 45 degrees durring the day? If the day does not get above 45 can i keep the plastic on with the heat lamps?
I fertilized regularly with 12-4-8. Should I try it again this year and use 10-10-10?
I live in Indianapolis and I winterized my Mandevilla last winter as you recommended. This past summer I took it outside and it returned to a big, beautiful, full plant with georgeous leaves but never bloomed. What have I done wrong and is it worth trying again? Thanks for your help.
Mandevilla winter hardy
I have a question: I just bought a mandaville vine and planted it outside so it could climb up on my porch. I have been reading the other comments about bringing the plant inside for the winter. I live in Wisconsin and I am wondering if mulching the vine heavily in fall and then placing a rose cone over it wouldn’t be enough protection from the harsh winters we can get here. Or should I just dig it up and bring it in the house for the winter. Please advise.
Hi I just purchased a Mandevilla from Walmart, I just fell in love with it. I live in Michigan and was concerned with it being a tropical plant, if it will go into a dormant stage before I bring it into the house for winter. What will be a good insecticide that will also be safe for my pets?
Thanks
I live northern Indiana (only 5 miles from Michigan) and I once wintered-over a Calla Lilly by placing several large bags of leaves (about three feet deep) on top of the plants after the first frost. It worked great. Could I do this same thing with my Mandevilla? Thanks
This is my first mandevilla and it is beautiful but this past week we have had a tremendous amount of rainfall. My plant is really drooping and not flowering. We finally discovered there are no drain holes in the pot. We did poke several holes for drainage. Is this the reason for the drooping leaves?
I should have looked this up earlier! I just bought a Mandevilla from walmart and I also did not know they were tropical. I fortunately haven’t yet planted it so I have a few questions. I live in Lovettsville, Virginia and I have a huge sun room. Lots of windows! Would a mandevilla make a nice indoor sun room plant or should I just go buy a container and have it outdoors during the summer and bring it into the sunroom for the winter? What size container does one need to keep this plant in? Is it going to become overwhelming? Thanks for you help!
Divide crowded mandevilla
i bought two mandevilla’s 4 months ago. they looked like they were too crowded, so i repotted them in bigger pots and put 6foot pieces of small fencing for them to grow. my flowers are growing very viberant and wild.this was the best thing for me to do. I have never had a green thumb but these flowers has made me understand gardening better.
can i divide my mandevilla’s to have more potted plants?
i live in tucson, AZ will the madevilla survive our winter? thank you!
Tucson is zone 9b.
I got a Mandevilla as a gift and I live in Hattiesburg, Ms. Can I plant it in a big pot and prune it like a bush or is it best to plant it in the ground with a trellis and cut it back to the ground each year?
Wintering mandevilla
I brought my Mandevilla into the house for the winter and placed it under a gro lux light. I leave it on all the time. Many of the leaves are drying up, but it is putting out many small long vine like growths. How much should I water it , and how much, if any, should I prune it , and what about the new vines it is putting out? Enjoy your site and appreciate your comments/advice.
Black spots
I am in ontario,canada, i bought my Mandevilla in when it started to get cold, it was doing really well now my leaves have black spots on them.What am i doing wrong?
I have read the tips about winterizing but I live in North Carolina and have 3 beautiful madevilla vines planted in the ground climbing my back fence. There is a pretty large looking root system. Since the odds are against it surviving the winter outside, can I dig them up, pot them and then winterize in the garage as has been suggested. Will this be too much stress on the plant since i will be cutting off some of the root system?
I certainly appreciate all the wonderful information on winterizing the mandevilla, but I did this last winter and found that come spring, late spring, early summer I had no flowers. It wasn’t until late August that I got beautiful flowers, but I am hoping I can do something this year to promote earlier blooms. My plants are now perfect, but soon I will lose them with a frost. Help!! and thanks.
I live in Shreveport La. During the summer I grew a beautiful Mandevilla on my trellis. Winter will be here my late December, my ques is should I cut back the plant and just mulch the roots at the base? and will it come back?
I am in Ohio and bought 20 Mandevilla Trellis plants at Walmart and planted and spaced them around the fence surrounding our pool. I wanted something that would vine and cover the fence and get thicker and thicker. Now I find out they may not survive the winter. I can’t dig them up and bring them in because they are vining beautifully and giving the privacy I wanted. I am mulching them heavily before winter. Will I have to start from scratch each year or will they be bigger each year?
No flowers
Hi! I overwintered my mandevilla in the same pot it was in last year. Now it is back outside and looks great: bushy with lots of glossy green leaves and it is growing like crazy. But there are no flowers! I fertilize weekly but I did not change or add any soil to the pot from last year. Any tips to encourage blooms?
To re-plant my mandevilla amabalis outside in the summer, should I remove the dead stalk from the bulbs? Presently there is no growth after it successfully grew inside all winter.
I winterized my mandevilla. Now I have put it outside. How long will it take to see new growth? Right now it looks completely dead.
Thank you
Winterize in GA
Thanks for all the info I have My mandavillas in the green house for the winter I live in Thomasville GA . Dont you think mandavillas should be okay here for the winter in the ground cut back and mulched heavy?
Store dry root method
I live in zone 5, I have 15 mandevilla plants, including 5 with red blooms, I have successfully winterized them inside for 2 years but I’ve developed allergies to indoor plants. Can I store them by the dry root method in an insulated garage wrapped in newspapers etc.? Or maybe in a box? I do like all of the information you list on Mandevilla’s. Sue

Winterize Mandevilla – Hi, I live in Austin, TX and planted 5 mandevillas outside, they are thriving…we are now expecting one additional and unseasonal frost in April, with rain and temps at 35-40 for lows…what should I do?
Prepare for winter
I have just brought my mandevilla plant in for the fall.. night temps were 50.. and when I did the leafs began to dry up and fall off Did I bring it in too soon Should I cut it back Now .. ??? thanks again for answering my question. Love this site
Betty
I am in Austin,Tx. I have a young Mandevilla in a 1 gallon pot. Should it be put in the ground and mulched, or placed in a larger pot and wintered over?
I just purchase a mandevilla trellis and did not realize its a tropical plant. I live in Richmond Virginia and wanted to know if I can plant it in the ground outside? Would it come back in the spring? Any suggestion would be greatly appreciated.
I will be keeping my Mandevilla in a greenhouse for the winter. Do I still need to cut it back if it is kept at a higher temp with more light?
Pruning for winter
I have a Mandevilla vine also and have read the comments on cutting back for winter…my fear is that cutting it back so much will kill it. I have a large, bushy vine in a pot wrapped around bamboo stakes to give it the bush shape and then on a trellis too . If I cut it all back to the 12 in., is there a chance I will kill it?
I have a huge trellis of Mandevilla….I live in Pennsylvania…what do you suggest on covering it outside when the temperatures drop. It is so big it would be impossible to bring it in.
