The Q&A Archives: Curling Leaves On Azaleas

Question: Our azaleas are planted on the west side of our house and the ground holds water at the bottom of the roots but can dry out at the top. Now the leaves on some are curling, what might be causing this and how can I cure it?

Answer: The most likely cause of curling leaves on your azaleas is poor drainage. When water stays soggy, it excludes air and eventually suffocates the roots. Can you improve the drainage in the area, or build a raised bed? If you can raise the root mass of the plants above the poor draining soil, they'll be much happier. You don't even need timbers - just remove the plants, add 12-14 inches of topsoil, slope the sides, and replant your azaleas. You can cover the raised area with mulch or bark to keep the soil from eroding. Hope you act quickly!
