Roses are pruned annually in early spring before they leaf out. They benefit from hard pruning and reward the gardener with vigorous new growth. New growth blooms best in Knock-Outs. However, if you miss a year, don't fret. They will still bloom but may get taller than desired. Remove all growth that isn't at least pencil width. Cut back old gray canes to the base - all the way down. Remove all stems growing toward the center. Leave 5 major canes about 2 ft high that are growing away from the center. It may sound drastic but it works. The goal is an open center that sunlight can penetrate and air can circulate. Other vital parts of routine rose care are full sun, fertilizer and weekly water. Regardless of the time of year, always remove dead, damaged, diseased and dying canes right away as they invite disease. This includes 2 canes that are rubbing against each other. Rubbing forms a wound where germs can enter. Remove one of the two canes. https://www.gardeningknowhow.com/.../knockout-roses/prune-knockout- roses.htm
