Outdoors, in the south, set out tubers in the spring when daytime temperatures are at least 70° F. Caladiums prefer a rich, sandy, well-drained soil, enhanced with super phosphate and potash; space bulbs 12 inches apart and cover with one inch of soil. Choose a semi- shaded, sheltered location.

Farther north, start in flats or small pots, using 2 to 3 inches of moistened peat moss or a soilless mix as a planting medium. Plant one inch deep with the knobby side up and grow in an area with a temperature of 75 to 80° F., keeping moist. Once rooted, transfer to soil-filled pots; move outdoors to semi-shade once summer has set in. Indoors, grow over the winter in a warm room with high humidity.


Spray foliage and water plant well during hot, dry weather. Remove flowers to prolong life of leaves. In early autumn, gradually dry out the tubers and store in dry peat moss, vermiculite, or perlite at 60°F.
