Ivy geraniums are happy-go-lucky plants, perfect for hanging containers. As long as they have plenty of bright sunlight and adequate water, the bright blooms will trail gracefully over the side of the pot, providing color all summer long and into fall. If you want to overwinter ivy geraniums, bring them in before the weather gets cold, because unfortunately, as sturdy as ivy geraniums are, the first hard freeze will turn them into compost.
Bring ivy geraniums indoors for the winter before the first hard frost of the season. Cut the stems of the ivy geranium back to about 5 inches.
Put the ivy geranium in a cool, dimly-lit place such as an unheated garage or basement. Be sure the room doesn't get cold enough to freeze.
Water the ivy geranium sparingly about once every month during the winter. The soil should be just barely damp. If the soil is too wet, the ivy geranium will rot.
Move the ivy geranium to a cool, well-lit room in late winter or early spring. At this time, gradually increase the amount of water you give the ivy geraniums in preparation for moving the plant outdoors.
Move the ivy geranium outdoors when you're sure all danger of frost has passed. Give the plant a feeding of all-purpose water-soluble fertilizer, according to the directions on the package. If the ivy geranium needs to be repotted, this is the best time to do it. Use a container with a drainage hole and fill it with a commercial potting mixture.
