My azaleas do not bloom. Previously, I would have flowers for a month at least but now flowers wither in a week or two. Please advise, I have been using azalea food, etc.

Are you using fertilizer on your azalea plants? If so, they may be getting too much nitrogen and not enough phosphorus. Nitrogen makes healthy green plants, but too much blocks blooming. Use a fertilizer higher in phosphorus or even a phosphorus only amendment, like bone meal, to get them to bloom.
