Mandevilla

The Mandevilla plant is often thought of as an annual but, in fact, it is very frost tender perennial. Once temperatures go below 50 degrees F., you can bring your Mandevilla plant indoors for the winter.
When you bring your Mandevilla flowers indoors, be sure to check the plant carefully for pests and treat these pests before bringing the plant indoors. You may want to cut back the plant by up to 1/3.
Once indoors, place your Mandevilla vine in a place where it will get bright, indirect light. Water the plant when the soil is dry to the touch.
In the spring, when the temperatures are consistently above 50 F., remove any dead leaves and move your Mandevilla plant back outside to enjoy for another summer.
