Elephant Ear is not frost hardy in colder climates and requires protection before freezing temperatures arrive. After frost damages the foliage, dig up bulbs or tubers and allow them to dry thoroughly before storing them in a cool, dry location until spring. Store them where temperatures remain above freezing and moisture levels stay low to prevent rot. In warm climates, plants may remain in the ground beneath a protective layer of mulch. Proper storage and winter care help preserve healthy bulbs, encourage vigorous spring growth, and maintain the impressive tropical foliage that makes Elephant Ear so popular.
