Caladiums require warm temperatures to sprout and grow. Caladiums are one of the few bulbs that require shade.
They also need to be kept evenly moist but the soil must well-drained, and they benefit from regular fertilizing
any organic fertilize will do, follow the instructions on the label.
Caladiums are hardy only to Zone 10, but the tubers can be dug and stored indoors in colder climates. When the foliage
yellows and droops in fall, lift the tubers, clean them of excess soil, and allow them to air-dry in a warm, sunny
location. When the foliage breaks away freely from the tubers, pack them in lightly moistened peat moss or sand
and keep them in a dry, well-ventilated place where the temperature is between 50-60°.
