Caladium bulbs are frost tender and will need to be dug and stored for the winter months. If you leave them outdoors they will freeze to death. Here's what to do: The leaves will die back when the temperatures get cool this fall. At that time, the tuber will need to rest before sprouting new leaves. When the leaves yellow and die, stop watering and dig the tuber, brush off excess soil, and store it in dry peatmoss. In the spring, replant the tuber in fresh potting soil and begin watering again.
