Q.Leaf diseases
The unit I moved to recently has a nice small garden, but I had to trim the shrubs today as I found black coating on some of the leaves. What is the best way to treat this?

What is the name of the involved plant and do you have a picture? It is also helpful to know where you live or at least the ag zone. Do the spots appear on the branches or just leaves? Sorry, but a bit more info will go a long way. If the affected plant is a maple, you may be seeing black tar spots. They are unsightly but not detrimental to the plant.
