Alton Bay narrows to a point at the bottom of Winnipesaukee, and the summer here is short, bright and busy. A Sharper Image Landscape keeps lawns up through it — mowing on a weekly turn, trimming what the deck misses, edging drives and walks so the boundary between lawn and pavement stays honest. The season opens with a cleanup that clears winter sand and debris, and finishes with one that takes the leaves off before the ground goes hard. Hillside yards under Mount Major dry unevenly and lean on that schedule more than most. Cut well, a lawn holds its lines all the way to Labor Day.
