Q.Caladium Bulb Dry
I dug caladium bulb in January. That time they were healthy like onion & I stored them but when today (4 march) I saw them they are like dry ginger. What could be reason ?

Unless your winter temps get much below freezing, you can leave caladium bulbs in the ground. They can tolerate down to -6 C (20 F) with a heavy mulch. When you do store them, it helps to cure them first and spray with a fungicide. Then they should be kept in sawdust or sand to prevent them from drying out completely.
I imagine yours dried out too much. Here are the winter care instructions:
