How to Grow Caladiums in Containers

Select a container large enough for the mature size of your caladium. Planting several small bulbs in a large container -- or one large bulb in a small container -- is most effective. Alternatively, cut a single, large bulb into three to five pieces, each with its own eye. Plant them in the large container.

Fill the container with a well-drained commercial potting mix. Caladium tubers in poorly drained soil are susceptible to rot. Amend the soil with a handful of bone meal.

Dig a 2-inch deep hole with the spade for each of your caladium tubers. Place each eyes up in its hole. Space the tubers from seven to 10 inches apart, depending on the width of the mature plants.

Water the newly planted tubers with the watering can or hose until the soil is soaked. Check the soil regularly and water whenever when it feels dry. Never allow the caladium's leaves to wilt.

Place your caladium container where it will receive filtered sunlight to partial shade. Full shade is acceptable in exceptionally hot climates. Shade, however, diminishes the foliage's color. Caladium's large leaves benefit from wind protection.

Give your caladium a biweekly to monthly application of soluble fertilizer.
