We don't get a lot of leaves in the fall here and most of the neighbors have lawn services so they take the cut grass and leaves with them. I wouldn't want my neighbors mulch anyway because their yards are all weeds. The only daylilies that I mulch with leaves are on the north side of my house. We live on a corner so the leaves blow into that bed and I just leave them there. That bed still gets some weeds but not as many. My backyard beds have woodchip mulch, but weeds eventually grow on top of the mulch unless I put some Preen on top, which I do. Nothing helps the violets though. They grow through anything.
