a maple back of our house leaves are curling up and turning black. when it was windy one day hundreds of these leaves were all over our driveway. You can see hundreds more on the tree. What is causing this. I called NDSU here in Fargo, No. Dak. and they didn't know what caused it, was looking into it.
