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.
