North of town the land lifts into the Vergennes hills, and after a warm April rain every lawn in Lowell seems to green up at once. Rosenzweig Lawn Service starts the year there — first cuts of the season, edges redefined, the winter's flattened mat of leaves finally gone. Summer settles into weekly mowing, trimming around posts and beds, clippings swept off the walk before the truck pulls away. Fall brings leaves in quantity, cleared while the river valley turns gold and the mornings go sharp. A tidy lawn is a small thing that makes a house look loved, and that is reason enough.
