Broad-leafed Alocasias

Alocasias are broad-leafed plants. Fairly hardy, the leaves and roots of alocasias can withstand lows of about 32 degrees Fahrenheit (0 degrees Celsius). With mulch, they're even more likely to endure the winter. There are three ways to winterize alocasias. First, you can dig up the plant before the first frost and care for it as a houseplant throughout the winter. Second, cut off foliage just above the tuber, and cover the stump with mulch. However, if you experience hard frosts, dig up the tuber and let it dry out in an airy place for a few days. Then, store it in a box filled with dry bark or chippings, in a frost-free place.
