How to grow caladium
Caladium x hortulanum
When to plant caladium
Plant caladium tubers in spring after the last frost, once the soil temperature reaches 70 F (Clemson), eyes pointing up. Caladiums are hardy only to zone 9 or 10; in colder areas dig the tubers in fall, store them dry at 70 to 75 F, and replant the next spring once the soil has warmed (NC State).
Caladium is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
