|Knockout roses are reasonably hardy and should not need any special preparation for winter. You can mulch over the soil to help moderate soil temperatures and avoid the freeze/thaw cycle which can heave plants out of the soil. Spring and summer are the best times to prune. You can prune your Knockout roses in the spring, just as new growth begins. You can take them down by one-third to one-half without harm. You can prune again in the summer to help keep them compact and blooming for most of the summer months. Feed in the spring when you prune them back.
