Plant care and instructions
Because caladiums are basically all leaves, they thrive on regular fertilizer. To keep plenty of new leaves coming on, feed with a balanced soluble fertilizer such as 10-10-10 twice a month. The great advantage of pot-grown caladiums is that you can move them about as needed to keep them warm. When nights become chilly in fall, bring them indoors and keep them in a sunny window, until the leaves begin to wither. At that point, let them dry out completely. To save space, you can collect the tubers, shake off the soil, and stash them in old hosiery or a mesh bag for up to five months. As long as the tubers are stored above 60d F, they will be ready to replant the following spring.
Light – Need bright light but not direct sunlight.
Place – Moderate shade indoors.
Water – When leaves appear, keep them evenly moist. Never allow it to dry out and keep humidity as high as practical.
Fertilizer – Feed weekly with a diluted water-soluble fertilizer to assure the continued growth of new leaves.
Temperature – 70º-85ºF
Mass plantings of caladiums create a focal point in the landscape. They provide a striking contrast with the green foliage of other plants, especially when planted in the foreground.
