Red Azalea Leaves Turn Yellowish Green

Question From: MARYLAND
Q: I have an azalea (red) that some part of the leaves turn a yellowish green durning the summer and then into the fall. Nothing seems to have happened because of this. I was just wondering if you knew what might be causing it. It is planted next to another azalea of the same color and both are planted against the back of the house and get full sun.

A:

Leaves of azaleas usually turn chlorotic do to lack of iron. I suggest you treat the plant with a product called Ironite at the recommended rate. Also sprinkle a handful of garden sulfer (by Espoma) on the surface of the soil in fall. Mulching the plants with an organic mulch will help to keep the soil moist. Happy Yardening, Nancy
