How and when should azalias be pruned and fertilized?

Azaleas should be pruned right after they finish blooming in the spring to encourage new growth and maintain their shape. Use sharp, clean pruning shears to remove any dead or weak branches and to shape the plant. Fertilize azaleas in early spring with a slow-release, acid-based fertilizer, specifically formulated for acid-loving plants, to promote healthy growth and vibrant blooms. Avoid fertilizing in late summer or fall, as this can stimulate new growth that may not harden off before winter.
