In zones 9-12, caladium tubers are hardy and do not need any special care to survive the winter. At the end of the summer, the plants will begin to go dormant. The leaves will droop and eventually wither away. Simply leave the tubers in the ground where they are and wait for the plants to re-emerge in spring.

Do caladiums go dormant indoors?

When grown indoors, they do best with lots of heat, bright but indirect light, and plenty of humidity. Even under the best conditions, caladium foliage lasts only a few months before the leaves start to die back and the plant goes dormant again, which is normal.

Can you keep caladiums from going dormant?

You can store caladium bulbs for several months in the right conditions. Don't try to keep them dormant for too long though, I recommend replanting them every spring. But if for some reason you are unable to plant them right away in the spring, keeping them in storage for a few extra weeks should be fine.
