Q: Is it too late to prune knockout roses that are overgrown?
A: Robert, Roses are best pruned in spring just as the buds are beginning to form. That's usually about the time forsythia blooms in landscape. Pruning stimulates new growth which can be damages by late frosts. Follow Mother Nature's lead not the calendar. Best And Happy Yardening, Nancy
