Your caladium will thrive best in bright to medium-bright indirect light. It can tolerate direct morning sun like in an eastern or northern window. Avoid areas in which it will be exposed to harsh afternoon sun.
Water your caladium when the top 25% of soil is dry. Water thoroughly, and be sure to empty the saucer of any excess water to prevent root rot. When the plant goes dormant in the winter, water very sparingly to allow the plant to rest. Begin watering again in the spring to “wake” the plant out of dormancy.
Your caladium prefers a humid environment. Mist the leaves regularly, place a humidifier nearby, or use a pebble tray to raise the humidity.
Your caladium prefers temperatures between 65-80°F. Avoid cold drafts and sudden temperature changes. Over winter, when the plant is naturally dormant, keep it in an area that stays above 60°F. In spring, very warm temperatures at 75°F or above are helpful to “wake up” your caladium more quickly.
