Thank you for your question regarding Mandevilla, a beautiful flowering woody-stemmed plant that winds its stems around any support and is so easy to grow. This plant will not make it outdoors in freezing temperatures. I overwintered mine in a cold entry hall with only a fluorescent light above. For keeping indoors, a cool room of 55 degrees in winter is fine, with added humidity since indoors is so dry. You can use a pebble tray to add humidity around the plant, it’s just a larger saucer filled with a couple inches of small pebbles and water added. Set the plant with its own saucer on top of the pebble tray saucer. Keep it in bright window.

An option for over-wintering your Mandevilla is to allow it go dormant. Keep the vine outside until it gets nice and cool and then move it into a cool garage or basement that maintains a winter temperature above freezing, around 50 F is ideal. In this scenario you should cut the plant back hard, to about 12 inches. Occasionally give it water so that it doesn’t dry out, but essentially leave it alone.

Bring it into the house when spring is just around the corner and let it start to grow. Then set it outside and enjoy this beautiful plant throughout the summer.
