Pruning a young azalea plant after the plant is through blooming will promote lateral branching and a more compact form. Prune lightly at the very tip of the branches for best results. Older azaleas should be pruned by removing larger branches from the interior of the plant. Removing the larger branches will allow more light in and the sunlight will inhibit disease. Cut away all dead or diseased wood below the infected area.

Older azaleas can be rejuvenated by cutting back the entire plant to 6 to 8 inches above the ground. If this method seems too severe, cut back the older plant over a 3 year period by pruning a third of the branches each year. Prune your azaleas in early spring before new growth begins.
