I always bring in the porch plants this time of year and after hosing out the undersides of pots/rims and then putting enough water into the pot to flush out for awhile (to get out the spiders, frogs, etc) I take to the basement. Our basement is little cooler and less dry than the upstairs and is walk-out so decent light. They do look less spectacular by the end of the Winter, but with some pruning, they spruce up in the summer.
