Make sure the soil is kept moist, but not soggy. The tubers will rot in soggy soil. To help keep the right level of soil moisture, mulch around the plants after you have planted them. Use potash and phosphorus as well as a 5-10-10 fertilizer monthly to ensure optimum growth. If you live in a region where the temperature drops below 70 degrees in the winter, dig up the caladium tubers. Replant them when the soil is warm again. If your caladium is in a container, simply bring it inside for the winter. Caladiums do well as house plants. Be sure they get some sunlight during the day. Fertilize every few weeks with a liquid fertilizer.  When your plant begins to die back, but before the first frost, dig up the tuber and discard the wilted leaves. Let the tubers dry out for a few days and then store them with dry peat moss in a box or paper bag in a dark cool place for the winter. Throw out any soft or empty feeling tubers. Plant when the soil is warm and ready for your caladiums to grow well.
