First light on the Cape arrives off the water, and by the time it reaches Chatham's gray-shingled streets the mowers are already ruled into their lines, edges cut tight against walkways and flower beds. Sorbello Landscaping Inc. works the sandy elbow of the Cape from New Seabury to Truro — mow and trim, lawn fertilization, aerating, dethatching and slice-seeding, spring and fall cleanups, mulch laid dark around hydrangeas that have to hold their color in a salt wind. They build the hard bones of a yard as well: patios and walkways, driveways and Belgian block edging, retaining walls, fire pits, water features, outdoor showers and kitchens, and landscape lighting that keeps a path readable after dusk. Irrigation is started in spring and shut down in fall, winter stakes go in before the wind turns, and the drive is cleared of snow while the harbor is still dark. What stays behind is the good part — a lawn lying even, a bed holding its line, a property that looks tended in every month of the Cape's long, weather-run year.
