Preparing Knock Outs for Winter

While visiting my parents in Lancaster County, PA (zone 6b) this summer, my husband and I pruned my mother's roses. She has a few polyanthas, climbing roses, and many Knock Outs. The roses responded well to the pruning as we removed lots of dead wood, and they now look so much better (I've seen pictures).

She has now asked me how she should prepare the Knock Outs for the winter. As I garden in Northern Ca, I have no experience with preparing roses for the winter. Does she cut them back before winter? If so, how much? Advice from northern gardeners would be very much appreciated.

Thanks,

Karen
