When and how to prune azaleas to ensure you don’t remove next year’s flowers

Azaleas don’t actually need pruning. However, here’s what to do if you ever need to remove dead or diseased branches, revitalise the azalea, control your plant’s shape or tidy it up a bit.

Why are my azalea leaves turning yellow and falling off?

Why are my azalea leaves turning yellow and falling off?
