Ringwood keeps a garden the size of a hillside up at Skylands, and something about living near it raises the standard for every front yard in town. Green Valley Landscaping NJ LLC works that standard into ordinary lawn care — a weekly cut held to an even height, trimmed corners, edges run true along the drive. Late May here smells like cut grass and mountain laurel at the same time, and the grass grows fast enough to keep a crew honest. On this rocky Highlands soil a green lawn is something you coax rather than assume. Watching one come in thick along a shaded street is its own small reward.
