I have 2 Quaking Aspens that I just purchased. They seem to have a black leaf blight. Leaves are turning black. I picked off the black leaves and have planted one of them and therefore they are not separated. One seems to be ok now but the one I planted is still getting the black leaves. Any idea what this is and how to treat it?

I too, planted a quaking aspen, and some of the leaves have turned black or have black blotches one them. I just assumed it was from the stress of transplanting them from the original container to our yard. Our young tree is about five feet tall, so I hope he is not trying to die on us.
