Row cover for roses?
Has anyone ever used row cover as a winter protection for roses? I have a long bed of landscape roses that are only about 1 foot tall, and I'm trying to decide how best to cover them this winter. There are about 12 bushes. Since I'm trying to get them to throw long canes and fill in the whole area, I'd rather not cover them all separately. Would a row cover work? Has anyone done this or is it not substantial enough for a MN winter? Any suggestions? Thanks!
