I'm just lazy about the amount of digging necessary, since there are several hundred irises involved. Still, that may be best.Terry's idea about a heavily mulched, protected spot is appealing but I'm going to ask the irisarians on iris-talk at Ginny's recommendation and I'll report on what they say. One iris friend overwintered hers in the basement and, as I feared, the results were poor. The plants were leggy and didn't fare well once out in the elements again. Thanks for the input!
