At Fishers Landing the St. Lawrence goes green-blue in July and the light off the water keeps the evenings long, which happens to be when river lawns look their best. Off the Top Lawncare & Landscaping cuts and keeps them — weekly mowing, trimming around docks, walls and shoreline stone, edging along walks, cleanups at the front and back of the season. River-lot grass grows quickly in that humidity, and a week skipped shows immediately from out on the water. Cottage yards ask for a light hand: no clippings blown toward the shore, no ruts left on soft ground near the bank. A place that looks cared for is half of what a summer up here is about.
