I have an azalea bush planted late March in a raised landscape bed by a professional landscaper. It initially looked great, and bloomed. Now many of the leaves are a bronze/brown color. I don't see any bugs on it. I'm not a master gardener by any means! What do you think is causing the problem? Thanks for your help.
It sounds like a nutrient issue. Give the plant some fertilizer. Also make sure the plant is getting enough water. It needs at least 1-2 inches of water a week.
