|Azaleas are routinely trimmed after they have finished flowering so they have all summer to develop new stems, leaves and flower buds for next spring's floral display. You can lightly trim your azaleas or you can prune them back as much as one third without stressing the plants. Taking off more than one third of the live growth can make recovery difficult so if your azaleas are very overgrown you may need to reduce their sizes over a 2-3 year period of time, taking off no more than about a third of the plant in a single pruning session. Good luck with your project!
