Old field walls still run through the woods along Tarrytown Road, stacked long before the parkways came, and the lawns that meet them look better for the company. Moretti Landscaping & Masonry tends that ground across the year — mowing, trimming and edging in season, cleanups once the maples finish, then plowing, shoveling and salting when the walls start wearing white caps. November in Greenburgh is a fast changeover; the last leaf pass and the first plowable inch can land in the same week. So the crew watches the sky and stays a step in front of it. What holds constant is the finish: nothing left in the beds, nothing left on the drive.
