I had 5 azalea bushes planted a couple of months ago. They were doing well until a couple of days ago. One by one the leaves started to turn brown. I water them twice a week as instructed on the card they came with and I gave them Miracle Gro as directed (after the problem with leaves). HELP me please. BHG Also, can you recommend a book specializing in azaleas?
Azalea Leaves Are Turning Brown and Crisp
It's possible that you didn't water enough; watering twice a week doesn't mean anything if the water is not getting deeply enough into the root ball and soil. Another possibility is that you planted the new azaleas too deeply. The top of the root ball should be on a level with, or slightly above, the surrounding soil. Here's an article with a general outline of how to keep azaleas: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/azaleas-noteworthy-shrubs-for-any-garden.htm
