While people talk about Caladium "bulbs", they are really grown from a tuberous
root. In the fall, the tuberous roots are dug up, cleaned and separated.
Make sure to have some buds on each divided section of root. Store the
roots in dry soil, or spaghnum moss in a dry, dark location until ready
to use next spring. Storage temperatures should be at least 40 degrees.
The largest tubers will produce the largest plants. Many people prefer to
start with new roots each year. Many home gardeners find the roots produced
by their plants are smaller, and turn to commercial growers who know how
to produce the biggest roots for the best plants.

indoors 6 weeks before the last frost date. We recommend individual containers.

Plant roots, round side up, 1 1/2"- 2" deep, in rich starter soil, peat moss,
or vermiculite. Roots should have a few buds on them. Water well the first
time, then keep the soil moist. The plant needs warm soil to sprout.
If planting as an indoor houseplant, plant roots directly into the container
they will grow in.
The plants are susceptible to drafts and sudden drops in temperature.
Tip: To promote more leaves, remove the largest bud in the center
of the root.

a month with a general purpose fertilizer. Indoors, use a liquid fertilizer
every couple of weeks. During the growing period, remove any dead or damaged
