However, at times, a pruning can keep the perennial from growing too quickly, and help it maintain optimal health and shape. Remove any damaged branches, or those that look diseased or dead, first. Cut the branch back to healthy wood and carefully pull the unwanted branch out of the shrub.Prune any branches clustered tightly together, especially if several cross each other. Also remove any that are beginning to intertwine. This allows sunlight and proper ventilation to reach the remaining branches.Cut any branches back that show accelerated growth by sticking out above other limbs. Level these with the remaining branches to allow the bush to keep a natural-looking shape. Trim any root shoots or "suckers" at the base of the shrub, or on the ground directly below; these can develop into additional plants that threaten the health of the pruned bush. However, the removed shoots can be rooted in pots to start additional bushes for your yard, or to give away.
