Caladium bulbs like warm moist (not soggy) soil. To get a jump start in northern climes, put your bulbs knobby side up about 1½" to 2" deep in a  shallow pan, bag or flat full of potting mix. Keep the mix warm (70's is nice) and you will find the bulbs shooting up and ready to transplant in the ground. A customer of Classic sent in this tip.
