Hello everyone, how do I overwinter my mandavilla in Detroit.
Mandavilla
I have a friend who over winter's hers in her attached garage. It gets some light from a window and doesn't freeze, but is cool. You just have to remember to water it every couple of weeks so it doesn't get over-dry.

I know when winter is closer from the e-mail. You may be asking what does winter and e-mail have in common? 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.”
We’ll try to give you the best info we can but remember we can’t guarantee your results.
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 plants will slow down. So now 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.
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.
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.
Some people place the plant in a clear plastic bag and over wintered it in their heated garage.
I hope that helps.... good luck. Let's us know how you do.
