Cercospora Leaf Spot

Cercospora is a disease that affects the Smooth, Panicle, Oakleaf, and Bigleaf Hydrangeas. It is most common in the months during July-October. The Disease rarely kills but can reduce the overall vigor of the plant. Frequent overhead irrigation can intensify the disease activity and subsequent defoliation and loss of vigor. The spots are first visible on older leaves at the bottom of the plant and spreads upward. The leaves that are severely spotted become yellow. To help reduce the spread of the infection spotted leaves should be removed anytime during the growing season and when possible, try to use drip line irrigation.
