I didn't realize caladiums were heavy feeders. I'm just starting to get hooked on them. I overwintered a pot successfully from last season and all the shoots are coming up along with a few leaves already! Apparently they can do pretty well in pots.
My Aunt has a glass enclosed patio at the beach and her son maintains the caladium garden she has. He lines her indoor stone beds with various types of caladiums. It always looks really nice.
Very nice, informative, and excellent follow-up to my Caladium hybridizing article!
For those who grow Caladiums in beds, here's a tip: start them in pots with large holes in the bottoms, then plant them in the bed, pot and all (pot soil level equal to bed soil level). Roots will grow out the bottom holes and keep them going, but this way, you won't have to fumble around in the bed trying to find all the tubers when it's time to dig them up. Just lift the pots when the leaves start to fade and you know you got all the tubers!
