Prune Red Twig Dogwood~Remove about a third of the stems at ground level every year. Cut out old, weak stems as well as well as those that are damaged, discolored, or growing poorly. This method of pruning keeps the color bright and the shrub vigorous. Cut back the entire shrub to 9 inches above the ground if it becomes overgrown or out of control. This is a good way to quickly renew the plant, but it leaves a bare spot in the landscape until it regrows.
