I have tried this last year but it started to die down and get mealybugs, any solutions, thank you in advanced

If I were going to do that again (tried once in OH,) I wouldn't let it get so cold before bringing it in, unless I had a basement to keep it cool, dark while dormant.

I had an alice du pont that I purchased from Logee's and it died for me also. I have one old red one I have had for years and I put her out in the Spring and take her in the middle of Sept. Spray her with a soapy spray once in awhile since she is in the Greenhouse all winter and that plant never stops blooming. This year it was on the deck in full sun for the entire summer and she bloomed all the time. The hummingbirds love her. I just make sure she has plenty of sun and water in the GH. I do trim mine to keep it from getting too big to handle. I have no dormant time for the one I have since I have no place else to keep her.

This nplant has been trained as a bush. I thought they didnt bloom during winter, and im not expecting mines too

I would guess it is because I have it in the greenhouse and the climate does not change. Mine blooms almost all winter , rests a month or so and then starts again and keeps going. I would guess there are no more than two months out of the year the plant does not have a bloom on it. Yes, mine is a bush in a big old square pot.
Nothing special or fancy. i do not even know the name of it because the dog ate the tag. I do remember it was patented so I never tried to propagate it.

Mandevilla are landscape plants here, either trained over walls or pruned as a bush, they bloom pretty much all year. I doubt they need a dormant period, they are just going dormant because it is cold.

Yes, that's what I meant about bringing it in before it gets cold, sorry if what I said didn't come out right. One year I tried to keep one in a west window and it still defoliated. Of course I overwatered it to death, trying to bring it back to life, before learning about dormancy and keeping such plants dry. Putting in basement in later years worked better. It's much easier to ignore a plant you hardly ever see. But in retrospect, going dormant may not be the best plan. If I still lived up north and wanted to save one of these, I'd try bringing it in before it got anywhere near cold enough for frost, to try to make sure the plant didn't get any cues to cause dormancy (assuming I had a really sunny window for it.)

My Mom has one in the ground here (a few miles away) which went dormant 2 winters ago, but stayed evergreen this past winter which was much more mild. A real winter might kill it one of these years, not supposed to be hardy here.

It's always worth a try if you already have the plant, and mean old man winter shows up! Wishing you luck!

Mandevilla Alice DuPont is Mandevilla x amoena and NOT M. laxa ... they are two different species. For my M. x amoena I overwinter it in my greenhouse and it gets cut back to within 3 inches of the soil line and watered very sparingly until I start to see new growth around March.

I'm growing M. laxa at the moment, started from seed .. it's extremely 'fragile' the first 2 years from seed so I don't cut it back and keep it in the highest point in the greenhouse for warmth over the winter.

I'll second what Jonna and Anne said. Mine grow and bloom all year 'round unless we get some really cold weather.

They certainly slow down in winter when the nights are cool, and grow rampantly in summer.

sorry correcting my ownself, have good day!

good day, same as above, just editing

Mm, don't think so, Rhamel. Anne always posts like that. I think when you post from a tablet or phone sometimes it automatically makes big letters or bold.

Actually I bold everything because I have bad cataracts and it helps me to see better. I'm having the surgery at the end of October so hopefully I'll be able to see again normally!

Xeramtheum Im truly sorry, sometimes I feel like someone is out to get me And also, on gardenweb, people are smart alecs and i usually associate the bolding and stuff with being a smart alec. Please forgive me, and i hope your eyes get better

X, I have that trouble too. If you're using a PC - setting the default font to a larger size in browser settings can help. If you're looking at a page of tiny writing still, hold the CTRL key and tap the + symbol until it's big enough to read. Works on pics too!

Good Idea purple!!!!

My mother had cataract surgery several years ago and it was very successful. She doesn't even talk about it which I think is best indicator.

Can't help but be a little nervous .. this time next week I'll have one eye that works if all goes well.

Good luck, Anne. Hope the surgery is a big success. My mother held out a long time, then finally had her cataracts done, and was amAZED!! at what she could then see. She also had a tiny lens implant so she could see a lot of stuff without her glasses, and she had been wearing glasses for nearly 70 years.

Rhamel if you're still looking, the mealybugs are quite hard to get rid of, but if you keep some rubbing alcohol and q-tips near the plant and just swipe the mealybugs off it as you see them, that will keep them under control and they won't damage the plant hardly at all. Hope your mandevilla makes it through the winter for you.

I have had a Mandevilla all summer and it is beautiful. We are in Ohio,
Zone 5. I am hoping to winter this plant indoors, but never having one
of these previously, I really do not know how to care for it, or if I can save
it un til Spring. Any suggestions will be greatly appreciated.
Thank you, MiraBelle
