Friday afternoon in Westfield, late June, and the air over by Sycamore Field smells like cut grass for hours after the mowers have moved on. Mel & Frank Landscaping puts that smell on residential streets all week — mowing, edging along the sidewalks, trimming fence lines and the base of the maples, blowing the walks clean before the truck pulls away. Spring brings cleanups and mulch; November brings the leaves, which in this town arrive by the ton. The standard is simple, which is that a yard should look finished, not just cut. Anybody can mow a lawn; leaving it squared away is the part worth doing.
