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.

July, 2021

Now I have 5 pots of this plant. Two red, two pink, and 1 white. I usually hate the color red, but this tone of red is very nice. A deep ruby red, not a true red. This is a very easy plant for a beginner. Takes very little care at all, and gifts you with lots of blooms for about ... read more 9 months of the year here in Zone 8b. Likes an occasional feeding of acid loving plants fertilizer. Water it about twice a week. Can take a lot of direct sun or a lot of just filtered sun, and still rewards you with a ton of blooms.

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 moree water. At the base of the vine I have planted some Heliconias. Where I live is frost-free (zone 11). I would highly recommend it if you live in the tropics.

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 morelmost 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.

Love the constant pink blooms. In a pot on the deck all (hot) summer in Muskoka, ON Canada (4B).
Need advice on how to keep it over the winter?
I will bring it in. Shall I cut it down? Repot?

I too LOVE this plant. It is growing up and over our fence, and flowers are beautiful, but I'm experiencing the same problem of leaves turning yellow and falling off at the bottom that some earlier commenters have mentioned. No one has offered a suggestion for how to prevent or stop. PLEASE if anyone has any suggestions let's hear from you.

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. This is my first time growing them but Even after only 3 weeks I would certainly buy one again. It seems to be sensitive to full, hot sun (I think I am seeing some sunburn spots) but oh my gosh I love this vine

This is a gorgeous plant, just seems a bit finicky. We've bee ngetting dumped on from the sky these last 3-4 weeks with rain every single day. So the bottom of my Mandevilla is dropping leaves (they don't like wet feet). Should be better once the rain stops, although I don't know if I'll keep it with our winters here since it's in the ground. Oh well - at least I can enjoy it for a season!!

I've had one on the porch and loved it - but that was on a trellis.
can you put this in hanging planters?

My Mandevillas were two of my first ventures into gardening. We have valiantly, and they elegantly, prospered and learned during our first year of gardening. I have two of the most beautiful vining plants with deep, georgous green foilage..and delicate, creamy blooms. I highly recommend this plant to new gardeners. Here on the coast of South Texas, I did have fierce battle with Japanese Beetles and Carpentar Ants. I am a firm believer in Neem Oil for both of these pests! My plants are encumbered with blooms..and the light, sweet aroma wafts on the air as we relax by the water garden.

I just bought a small Red Riding Hood Diplandenia and am doing research to see what I have. I live in zone 7 the foothills of NC Mountains. Has anyone wintered these over as a house plant? I think the winters might be to cold here, I just moved to NC April 1 from MA, so I have no real experience.

I bought two white Mandevillas for pots on my porch; one of them is growing and blooming like crazy and the other is losing leaves and the buds are falling off before they open. I water them equally (lately every day, as we've had record-breaking high temps here in N.O.) and they both get alot of sun, although the sickly one gets a little more afternoon sun. I have no idea what the problem is, but generally Mandevilla does very well here.

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.

Any suggestions?

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!

My mandevilla is also turning yellow leaves.
SF Bay Area.
in containers, water every day, balanced fertilizer. a few leaves started turning yellow, now about a dozen are yellowed and dropping off. It's mid July.... time for it to start going dormant? When does that happen for this area?

I love this plant and don't want to lose it...have matching pair. These flowers are so pretty and perfect, they should be illegal! ;-)

I found the most beautiful RED Mandevilla! It opens up pink and next day turns into a dark, vivid red. I only had pink ones before, but this is gorgeous. Had it for about a month and it blooms constantly. The blooms are a bit larger than the pink ones. Here, in Guam,they grow and bloom year round, and they get quite large. A perfect addition to my garden.

I have found the insecticidal soaps effective against aphids. These soaps are also much safer to use indoors in a sunroom than the more toxic insecticides. You should be able to find them at any nursery, or the garden section in places like Lowes, HD, etc.

My Mandevilla always gives warning about thirst and lets the flower buds die first while the leaves stay healthy and growing. They like the partial shade here in east central Florida (U.S.) because the sun is so hot.

I live near Houston, Texas (U.S.) and my Mandevillas are growing wonderfully! I have to water a lot and use water-soluble fertilizer twice monthly. This is my first year with them. I read elsewhere to cut the stems back during winter and to bring them inside, keeping them watered. I hate the thought of cutting them back - they're so beautiful. We have mild winters; however we do have an occasional freeze.

My vine is a prolific bloomer and is rapidly covering a chainlink fence. It is 10 feet and growing; it blooms year-round in southern Florida (U.S.); it's a garden favorite down here!
