Hello. I have azaleas that are blooming right now and are not flowering very much. When should I prune them?? When to fertilize? Others in my neighborhood have them flowering so much you can barely see the green leafs. How can I accomplish this?????
Regular pruning isn't required, if you wish to improve their shape - do so immediately after flowering.
I don't see what part of the country you are in to guess at your soil type...if your azaleas are planted in soil high in organic content (compost, whether clay or sandy base), the main reasons for failure to bloom are -
Too much shade.
Pruning wrong time of year.
Over fertilization produces vegetative growth (leaves) rather than flower buds.
Drought in summer when they are setting buds for the next season's flowers.
