We live with huge Oaks, Poplar, Maple, Holly. We have two fish pools, very large Azaleas and I think about a thousand Hellebores. We used to put down pine bark in the walk areas but back problems said no more. We want to leave the leaves down, maybe just run a mower over them where we can. Just to keep them from matting. What to do about designated walk ways or do we just things lay where they fall.
