Q: When is the right time to plant caladium bulbs in Central Texas?
A: It is best to wait until after May 1st to plant caladium bulbs. The soil temperatures should have warmed up to 70 degrees by then. If you wish to have caladiums up and growing as soon as possible, you can plant caladium plants. These have been grown in a nursery and are already a few inches tall. However, remember that caladiums cannot take cold weather, so you still run a risk even when you use these transplants if you plant them before the first of May.
