Plant care and instructions
In the warm, humid climates of zones 8 and 9, plant caladium tubers directly into the ground in spring. In most other areas, you’ll save several weeks of growing time by transplanting potted plants that are already up and growing. To make watering and fertilizing easier, consider planting three tubers (or plants) in 6-inch pots and sink the pots up to their rims in the beds. The pots collect and hold water, stave off invasions from thirsty tree roots, and make it simple to lift and collect the tubers in fall.
Light – Full Sun to Partial Sun; Bright Direct Indoors
Place – Indirect light or moderate shade indoors. The narrower the leaves, the greater the sun it can withstand.
Water – When leaves appear, keep them evenly moist. Never allow it to dry out and keep humidity as high as practical.
Fertilizer – Fertilize weekly during the growing season with liquid or use slow-release pellets.
Temperature – Around 70ºF.
