I have dark spots on the leaves of my limelight hydrangea. What is causing this and how to I treat it?
My limelight hydrangea is in full sun and we have had a particularly dry summer.

Can you include a photo? This could be due to many reasons. Many times, even thought these are marketed for full sun, they will appreciate some shade. This is especially true for hot, and dry periods.
A photo will help me to determine the exact cause of the spots.
