I have a row of 10 privet hedges. Two of them started to lose leaves and then it has spread to a few more hedges. Some of the leaves have little brown dots on them. Anybody know what this might be? And if so, what can I do to save them? I'm in New York state. Thank you in advance

Looks like fungus of some sort. Maybe someone else knows the exact kind, but I think fungicides tend to be pretty generic.

From this picture, it appears they are getting more shade than they would like, which probably hurts their ability to fight off pathogens. You may have an uphill battle.
