Likely causes
Fungal Leaf Spot
Most likelyHow to tell: You will see brown or black circular spots that may have a yellow halo. These often appear after long periods of rain or high humidity.
What to do: Remove and destroy any infected leaves to stop the spread. Improve airflow by pruning nearby branches and avoid overhead watering that keeps the foliage wet.
Cercospora Leaf Spot
PossibleHow to tell: This fungus creates angular, dark spots that are limited by the leaf veins. It typically shows up in late summer as the plant matures.
What to do: Clean up all fallen leaves around the base of the plant in autumn. Apply a copper based fungicide if the infection is severe and threatens the overall health of the shrub.

When to worry
It is normal to see a few spots late in the season as the plant prepares for dormancy. Worry only if the spots cover more than half the foliage or cause premature leaf drop.
Stopping it coming back
Space your plants properly to ensure good air movement and always water at the soil level rather than wetting the leaves.
