Are you keeping up with it? Dh and I have been working like dogs to keep up with the leaves especially for Halloween. Even trying to mulch (mow the leaves), rake, leaf blow and vacuum, it still getting ahead of us. We have four large trees. Two of them are sycamores with giant leaves. Sycamores drop leaves, bark and branches all the time. On the up side, they have fantastic shade and they appear to be lightening resistant.
