Has anyone here ever kept a Mandevilla over winter?? What kind of care did you give it?? Someone told me they need to go dormant and lose their leaves. I just potted it up and set it in a south window and was going to treat it as any houseplant. I also cut back and potted up a Lantana although I've read that they don't do well inside, but just thought I'd try it this year. Also cut back and repotted some New Guinea impatiens. What other plants besides Geraniums do you have good luck with wintering over??

Mandevilla Overwintering a Mandevilla vine
As we get closer to winter we receive a lot of the same question – “What can I do or how do I take care of my mandevilla during the winter.” Mandevilla has become a very big spring blooming crop, and is usually grown outside on a deck, patio, sun porch, etc.
As the nights begin to cool off the Mandevilla will slow down. That is the time to give them some food to harden them up for the long winter.
Try to use a liquid fertilizer with a high middle number e.g. 10-56-14, (Lightly) since you can cause fertilizer burn. We are not trying to promote growth but to toughen the plant up. Don’t go over board with the fertilizer; let the plant stay outside as long as possible. It should be able to handle high 40’s for brief periods.
After about 3 weeks (if you can hold out that long weather permitting) prune the plant back. Not just tipping the plant but cutting it down to about 12 inches above the soil line. I would also treat this vining plant for any possible pests probelms since it will be going indoors for the winter.
Next we want to begin slowing up on the water and let the plant run on the dry side. Remember that we have given the plant some fertilizer and removed a lot of growth so the requirements for water should drop.
When you bring the plant inside place it in as much light as possible. You are looking for maintenance not growth. You'll probably get some quick new growth, just try to maintain it. Some people place the plant in a clear plastic bag and over wintered their Mandevilla in their heated garage.
Try to maintain the plant on the dry side throughout the winter.
When spring comes you can move the plant outside. Expect the growth produced during the winter to be burned off!!!
Although, we cannot guarantee the above method will work you, it is a guideline that has worked for others you can try.
I hope that helps.... good luck. Let's us know how you do.

Thanks, Loon, you are always so helpful. It just seemed easier to ask here than do a search. Thanks for introducing me to a new site.
Hey Guys, I've had a mandiville for 6 years, I bring it in just as the days are getting shorter and the temp is going down. Prune it, check for bugs etc, and one last 1/2 dose of fertilizer, and set it in my south window. It looks like it is happy. then in the spring I repot it in new soil and set outside on the deck, I use a 18 inch pot. I get a ton of blooms and a vine that reaches 25 feet last summer.
