something is stripping the leaves from a caragana hedge
I have had a caragana hedge for a number of years. Four years ago I cut it back to only a few inches and it is regrowing as hoped. However, every summer since, about now, the hedge is decimated by powdery mildew and something that is stripping off the leaves. Thoughts?

It would be difficult to say what is eating your hedge from the description but I would suggest a Neem Oil treatment.
It should take care of most damaging insects and also works as a fungicide.
