Answer: Azaleas do not need much routine pruning with the exception of removing and tidying broken or damaged branches when they occur. An overall pruning or shearing will ruin the natural shape of the plant. If the plant is outgrowing its allotted space, you can try to reduce the size somewhat by selectively thinning out the longest branches or removing the occasional overly long branch tip. Do this right after the plant blooms in the spring. If it requires substantial pruning for size every year, you might want to consider transplanting to a location with more space and/or replacing it with a cultivar that matures to a smaller size.
