I'm in Birmingham,Al. I had encore azaleas (april) put in my yard with Miracle Grow Garden Soil and good fertilizer where needed. I think they were planted correctly. They, and other regular, established azaleas all developed light spots on the leaves so we fertilized. I have a sprinkler system and we water if necessary in between. We spray when we see the recent beatles. Help save them!

Light green or yellowish patches on leaves sometimes accompanied by brown spots on the back side of leaves is a sign of rhododendron powdery mildew (Microsphaera azaleae). A fungicide should help stop the progression of the disease. Or you may want to prune them back a little to remove the fungal spores and to open them up to better air circulation. Good luck with your azaleas!
