Potting and Storage. These make good potted plants, but do not allow pot to

After flowering in pots: In Autumn when foliage goes yellow, reduce
watering & allow the pot to dry out completely. After flowering, pots can
be stored on their sides under eaves, until new pink growth is seen next
Spring at which time you resume limited watering and feed generously again.
After flowering in the garden: When growth has died off, dig tubers up,
wash off the dirt & allow the tubers to air dry for 4-5 days (this hardens
the skins.) Store the dried tubers in dry peat moss or sand in a cool dry
position until Spring growth occurs at which time the tubers should be
