Do you have a Greenhouse Dme?

In a cool, dry place - either in pots, cut down to about 4 inches, remove the leaves, don't water, unheated room. I think you get pretty cold there, so I don't think a garage or shed will do, although it would in Britain. These plants will withstand up to ten degrees of frost, but wet causes them to rot.

mine are in the shed but have light from window and flowering again
