Sudden & Total Yellowing of Azalea Leaves
Suddenly, all four of my mature azaleas have yellowed. Maybe 20% of the leaves in late October. I have never seen this before. I'm sure this is not chlorosis and I see no sign of lace bugs. Some of the leaves remain green on the tips but their is no veining.
Has anyone experienced this? Better yet, does anyone have an idea what the cause is?
