I always cut off flower stalks to encourage more leaves, Donald. Lots of fert and water at this stage of the game will help produce more gorgeous leaves too.
I have another Caladium question in case Bill drops by to answer yours. I planted some Caladiums last September that were beautiful all the way through until December. Will they stay dormant through the spring and come up again in the fall? There's no sign of them sprouting so far, and all my other Caladiums are going strong.
