Watering
Caladiums enjoy evenly moist soil, however, make sure that the soil is damp but not soggy. Water your Caladium thoroughly when the top inch of soil is dry, usually about once a week. Being a tropical tuber plant, Caladiums appreciate high humidity.

Fertilizer
The best fertilizers for Caladiums are fertilizers low in phosphorus (P) such as NPK 10-5-10 or 20-10-10. Fertilize caladiums twice in the growing season in spring and summer. Caladiums prefer a soil pH between 6 and 6.5 for optimal nutrient intake

Light
Caladiums grow best in shade to part shade (two to four hours of direct sun, preferably morning) or bright dappled light. In these conditions, they produce the lushest growth with large, colorful leaves

Temperature
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.

Repotting
Upon purchasing, if the pot is too small, proceed to repot the plant so that it may grow adequately. After that, every 2 or 3 years and preferably in spring, repot your caladium in a pot of a slightly larger size. Caladium roots hate having too much water.
