When does mandevilla vine bloom? How long do mandevillas flower? All good questions, and the answers depend on a number of factors. Read on for specific information about the mandevilla blooming season.
How Long is the Mandevilla Bloom Period?
How long is the mandevilla blooming season, and does mandevilla bloom all summer? Yes, you’ll usually see the first mandevilla flowers in early summer and the mandevilla bloom period lasts until the first frost in autumn.
This beautiful vine is tougher than it looks, but it is killed by frost in USDA plant hardiness zones 8 and 9. However, the roots are still alive and the plant will grow back in spring. In climates north of zone 8, the plant may not survive the winter. The solution is to grow mandevilla in a pot and bring it indoors when temps reach about 40 to 50 degrees F. (4-10 C.).
Caring for Mandevilla Grown Outdoors
Plant mandevilla in partial shade and well-drained soil. Water the plant regularly, but allow the soil to dry between each irrigation. Fertilize mandevilla regularly during the growing season.
To maintain your young mandevilla plant, train the vine to grow on a trellis. Pinch young plants to encourage bushy growth and prune as needed to maintain the desired size and shape.
Mandevilla Blooming Season for Plants Grown Indoors
Mandevilla is suitable for growing indoors year round, but this tropical plant needs a warm, sunny location such as a south-facing window, especially in winter. If possible, move the plant outdoors during the summer months.
Water when the soil feels dry to the touch, then allow the pot to drain thoroughly. Fertilize the plant regularly during spring and summer.
Repot the mandevilla plant to a slightly larger pot with a drainage hole every spring. Pinch wilted blooms regularly and prune the plant by half or less in late autumn.

My Mandevilla Vine Is Not Blooming
Mandevillas (Mandevilla spp.) are tropical vines that produce showy trumpet-shaped flowers. Vines in this genus are generally hardy in U.S. Department of Agriculture plant hardiness zones 9 through 11, although some mandavilla species vary slightly. For example, Mandevilla boliviensis and Mandevilla amabilis, a mandevilla hybrid, are both hardy in USDA zones 10 through 11, notes Missouri Botanical Garden. Mandevillas are prolific bloomers, but if your vine isn’t blooming, it may not be receiving the proper care or growing conditions.
Care Of The Mandevilla
Plant mandevilla where the plant will get at least six to eight hours of sunlight per day. Mandevilla grows in nearly any well-drained soil. Locate your mandevilla near a supportive structure such as a sturdy fence, trellis or arbor. Continue to pinch the tips as needed, using your fingernails or garden pruners, to promote bushiness and keep the plant balanced and neat. Mix the fertilizer according to specifications provided on the label. Prune mandevilla in late winter or early spring.

I have one in a big pot. It gets filtered sun all day long. I give it plenty of water and fertilizer, but not too much of each. It grows like crazy, and stays blooming all season long. Lost the first one, because I stupidly left out in below freezing weather. Bought another one today at Lowes for a dollar. I will see if I have the same good luck. This takes our salty water really well. A good plant and flower for a gardening beginner. Super easy to grow.

This flowering vine is very common in Panama where I live. Many people have it planted in their yards. While it seems to grow faster in the tropical lowlands it does well for me at 1400 meters. The vine needs support and it is best to tie it to some kind of trellis. I tried to root it at various times without success. Recently it had seed pods with seeds so I planted three seeds. Two of them sprouted readily so I now have two vigorous seedlings in pots. I have harvested more seeds which I hope to plant soon. This vine has very attractive flowers and here it is in flower 365 days a year. In the dry season I water it. It has grown up to the second floor of my house. It is about 6 years old. I have a small pool with a waterfall below it and there are always some of it's flowers floating on th. read more e water. At the base of the vine I have planted some Heliconias.

I have grown one of the red dipladenias (learned from reading earlier comments difference from mandeville) for four years now and loooove this vine. It grows great for me in full sun, which is about 6 hours/day in my yard in the Triad region of NC. I usually have to water at least every other day. If I buy a small plant in the spring, it may reach 15 feet by fall and be covered with profuse blooms all summer.
This is the second year I've over wintered a vine. I bring it in when it gets cold. Both years I waited too long, until close to frost temperatures (once it was after the 30 deg. temps, but still salvaged the vine) and the vine shed terribly when I brought it in. It was autumn in my kitchen, green leaves falling everywhere the next few days until the plant was a. read more lmost bare. So both years I pruned the vine way back, which was probably a good idea irregardless. I leave it in my kitchen, in my sunniest window, which isn't all that sunny, and supplement it with some CFL lightbulbs, about 150-watt incandescent equivalent, and water a couple times/week (it's pretty pot-bound by fall but I don't transplant until spring). I don't feed it. I get a bit of growth over the winter but no blooms. Last year I started feeding in the spring and used a fertilizer high in nitrogen. Oh my gosh, I couldn't figure out why I had no blooms, but the vine took off like it was on steroids. I had the largest and bushiest mandeville I'd ever seen. Later I found out you need to use a fertilizer lower in nitrogen, and higher in phosphorus if you want flowers and not green growth. Once I switched fertilizers, it started blooming. This year I think I will repot and start fertilizing for green growth now and then it will be big and bushy when I put it out to bloom when it gets warm enough. Of course, I'll have to double up on the light bulbs at minimum. Anyways, I don't know if what I'm doing is "right" or not, I'm only sharing what has worked for me (and if it ain't broke. ).
If you like bright flowers, you can't beat this vine for ease of growing (I kill stuff. year #5 trying to grow lavender, wish me luck, retrying some other things like phlox and columbine, too) and volume of blooms.

I bought a Mandevilla Boliviensis last summer for the sunny west facing window of my appartment. Unfortunately it wasn't a very bright summer in Dublin, Ireland (53 deg Northern).
It was doing okay, so I gave him some tomatoe food as I read it wanted somewhere. For whatever reason, I'm not sure, the leaves turned brown and fell off. I have not been able to bring it back to life since.
Potted up when purchased, complete with bamboo (Was growing well), Continued to grow, was fed NPK 5.5.10, stopped growing. New leaves and shoots turned brown and fell off, established leaves never died.
Watered soil out thuroughly and next year (9 months later) put in a very sunny location. Showed good indications of climbing but then . read more for no reason and no feeding, same browning of leves and climbers occured again.
Moved out of sun, no change to date.
I love the plant, his name is Douglas, but he doesn't seem to do well under my care.

My mandevilla is BEAUTIFUL. I wanted a red one, but instead I got one that flowers first an unctuous light pink color, and then turns darker pink the next day.

Grown in large pots in the summer, this year I put the pots in the cool dim basement after I cut the vines back to 6 inches (before frost). I added a cup of water to each pot just once during the 5 months they have been downstairs. Today I brought them upstairs and they have small sprouts from the base, and some short fresh green vines from the older pieces.
Two weeks later I now have a dozen new sprouts on each plant. I've fertilized lightly.

I have no idea what the problem is, but generally Mandevilla does very well here.

To address the Mandevilla dropping leaves issue:
Re-potting can be enough of a reason for the Mandevilla to enter a bit of a slump. It will perk up if it is in good lighting. It can also droop or drop leaves if the sun is too strong.
I have had an awful time with aphids on my plants as well. For that reason, I almost never place my Mandevilla near other susceptable plants. I still give Mandevilla a positive rating because it's a beautiful, relatively easy to care for plant.
Somebody correct me if I am wrong, but I believe that Mandevilla might be deciduous and needs a dormancy period every so often? So if your plant just starts to randomly act weird (especially in Fall/Winter), it could just be in need of a pruning and some rest.
On Jan 19, 2005, mickbrown from Tongala, Victoria,
I live in southern Australian, in a mild-warm climate. I just bought a bright-red Mandevilla the other day and re-potted it when I got it home. Almost the next day, leaves started turing yellow and falling off. It's still in bloom (magnificent color!) and the buds are still there but am concerned about this problem. I've looked at the other growers' notes on this, but some say it probably needs more water, and others say it probably needs less. I water it every day, as its summer here and hot.

At a time when most taxonomists are eager to further divide plant species, I don't understand why they lumped mandevilla and dipladenia into the same category. The plants are VERY different in appearance. One has large, rippled leaves up to 6 inches long and 3 inches wide, with large blooms in pink, light pink, or white. It is the traditional mandevilla.
The other plant has small, smooth, shiny leaves up to 2 inches long and smaller blooms in more intense shades of hot pink to red. It was called dipladenia. I have this latter type.
I have found the best time to propagate the vines here in Missouri is mid-summer. I put cuttings under plastic and they root fairly quickly. Mine continue to bloom all winter in the greenhouse, and all summer in the landscape.
Both types. read more get much taller than listed in the details. about 10 to 12 feet for both. Of course, you can allow it to loop back down on the trellis to keep it at a lower height.
Also, for those who are new to this plant: Don't cut back the long, stringy tip growth that appears. This will set leaves and flower buds after a while. (I kept pruning mine back to keep the plant compact, and then wondered why it would not bloom!)

My response says neutral but it's not the fault of the plant.
I planted my pink bloom mandevilla in a large brick planter with a large trellis above it. It was BEAUTIFUL, then started looking quite ill. On closer inspection, I broke open one of the woody vines and it was filled with carpenter ants! My hubby sprayed it with carpenter ant killer and they are all gone, thank goodness, but the damage was done.
I cut all the vines down to the nub and after some weeks of shock, I have about 3 foot long vines now with healthy looking leaves.
You may have to do a similar drastic thing with the aphids - kill them completely and cut off all the damaged areas and cross your fingers.
Another positive besides the beauty and rapid growth - -. read more - the deer don't seem interested in eating my mandevilla. Hooray!

This is to answer the leaves yellow and falling off problem, perhaps overwatering might be the problem.With regards to aphids and such, in my experience, I have discovered a natural pesticide/immunnity builder call neem oil.If you get it in concentrated form it is inexpensive and really works, it kills the eggs of the pests before they have a chance to hatch and boosts the immune system of the plant but do not spray actual flowers.The flowers don't like to be coated with the stuff-it stains them but it makes the leaves beautifully shiny.

It's a prolific climber and needs a trellis or other form of support! Blooms have developed in threes and seems to enjoy the pine straw mulch used to maintain moisture.
