The asiatics need a cold period. I have heard of some people successfully wintering them in pots in an unheated garage. They won't be happy in a 60 degree basement. The caladiums can be stored in the basement. I believe 60 to 65 degrees is the right temp. for wintering them. Perhaps someone else will chime in on that.

hh2,
thank you for that very helpful info. I guess this lily challenge is now going to push me to find out if my screened porch can be for me what an unheated garage is for others.i'm thinking that i'll bring the potted lilies up against the house wall of the porch and cover with a blanket, or put them in a cupboard. do you think that next spring i should replace the soil in their pots and then fertilize them after they show green? (these are just your typical 1 gal. nursery pots; i never got around to filling large glazed pots with them.....) thank you again,
Mindy

p.s. with regards to the calladium going to the 60 degree cellar, can i leave them in their plastic pots or must i remove them from soil? (i have lost their bare corms before...)
