Answer: Plant your caladiums outside when daytime temperatures are 70 degrees F or higher. Space the tubers 12" apart and cover with 1" of soil (2 parts loam, 2 parts peat moss, 1 part well rotted or dried cow manure and 1 part coarse sand. Feed every 2-3 weeks during the growing season with a weak fertilizer solution. In fall, when the foliage falls over, or frost threatens, dig up the roots with soil and tops and let them dry in an airy place out of sunlight for about a week or until the tops come away with a gentle tug. Shake off the soil, and dust the roots with a combination fungicide-insecticide and store over the winter at about 55-60 degrees F.
