For this year, you can prune bushes that are too high for them to reach. The plants will sprout new, tender growth before fall; but not grow like crazy. And leave branches on the ground for them from trees you limb, especially the leafy, deciduous trees. They'll come eat the leaves and smaller branches/buds.For next year, I think clover is good for the summer early fall. You can mix in turnips and winter rye so that it will be ready for late October or mid November.
I wish the tree was still on this old stump, it would pay for the whole project and then some I bet!
