Answer: It sounds as though your azaleas are really struggling and I think if they were mine I would dig them up and replant them. For the most part, azaleas grow best in morning sun and shade from hot afternoon sunshine (there are some sun loving azaleas so check to see which ones you have). They also prefer acidic soils. Amend the planting bed with organic matter prior to replanting. Allow them to re-establish their roots over the summer months. Feed them with a specialized Rhododendron/Azalea fertilizer. Next spring, after their normal flowering period, prune them back by a few inches to promote healthy new growth. You should end up with healthy, happy azaleas that bloom reliably for you. Best wishes with your plants!
