Like most plants, caladiums grow best in fertile, well drained soil. You can improve the texture and fertility of your soil by adding compost or top soil at planting time. During the growing season, caladiums will appreciate an occasional dose of liquid fertilizer. To stimulate bushier growth, some varieties of caladiums can be "de-eyed" before planting. Use a paring knife to carefully cut out one or more of the primary sprouts, taking care not to damage the surrounding tissue or any smaller buds.
Though at first this will set the plant back by a couple weeks, many other sprouts will soon begin developing, giving you a shorter, yet fuller plant. Caladiums are tropical plants and the tubers will not survive cold winters. If you live in USDA zones , simply treat your caladiums as annuals. There is no need to dig the tubers at the end of the growing season as they will disintegrate over the winter. In USDA hardiness zone 8, caladiums are not reliably hardy, so you can try insulating the tubers from cold with a thick layer of mulch.

We recommend watering when the top inch of the soil starts to feel dry to the touch. Stop watering once you see the leaves begin to die back.
