Pruning pjm rhododendron — FAQ
When should I prune pjm rhododendron?
Immediately after flowering (mid to late spring). Pinch or cut off spent flower clusters just above the uppermost leaf whorl. For shaping, cut back wayward stems to a healthy lateral bud. PJM responds well to light heading cuts made right after bloom but resents late-season pruning.
How often does pjm rhododendron need pruning?
Annually for deadheading; shaping every 2-3 years as needed. PJM rhododendron is a compact, cold-hardy hybrid that benefits from annual deadheading right after its vivid purple-pink spring bloom. Lightly shape immediately after flowering if needed. Its naturally dense habit means heavy pruning is rarely required. Never prune after midsummer, as next year's flower buds set early and will be removed along with the shoots.
