July goes flat and bright here, the sort of afternoon where heat lifts off the pavement and the only shade on the block sits under a parkway maple. J-Mow's Lawn Care keeps the route moving through it around Melrose, mowing on schedule, trimming close along fences and stoops, edging the sidewalk seams and blowing the clippings off the walks before pulling away. Lots sit shoulder to shoulder in this neighborhood, so a straight line on one yard makes the one beside it look better too. Grass runs hard through a humid stretch and then sulks in a dry one, and the cut has to answer both. Done right, a block of small lawns reads as one long green run.
