Down in the river bottom the silver maples and cottonwoods throw long shade across Lyons yards, and grass grown under them wants a different touch than grass out in the open. Don's Quality Lawn Maintenance reads that difference — mowing at the height shade will forgive, trimming close around trunks and fence posts, clearing the clippings before they mat down. Late June evenings here smell green and river-damp, and a lawn finished at that hour holds its lines like something combed. The work is unhurried and exact, and it shows most in the edge along every walk. A yard should look cared for from the sidewalk, and these do.
