Plantings of Caladiums are generally past their prime by the time we reach the early part of October, or they will be soon, and it's time to decide what you want to do with them. Your choices are: pull them up and throw them away; leave the tubers in the ground; or dig them up, store the tubers over the winter, and plant them again next year.
Caladiums will give you more than one year of color
