Overwintering Mandevilla Plants

Question

Can a Mandevilla plant be over wintered in an unheated garage if it is elevated off the concrete floor?

Answer 1

The mandevilla will have a better chance of making it through the winter if you cut it back, bring it into the house, and treat it as a houseplant. This article has more information: https://www.gardeningknowhow.com/ornamental/vines/mandevilla/growing-mandevilla-indoors.htm
