I have grown callas successfully for years and know how to store the bulbs over winter but I made a big mistake last Spring and the bulbs I had stored over winter never got put into the ground. Two shallow boxes of bulbs sat naked all summer. They don't seem to be totally dried up, several have sprouts. I don't know what I should do with them now. Store dry and cool or barely damp and cool so they don't dry out beyond repair?
