October turns the vine rows around Southold to gold and hammered copper, and the air goes clear enough to see water from the high ground on either side. North Fork Landscapes LLC works this stretch of farm road and shoreline with mowing, edging, string trimming and seasonal cleanups. Harvest season is also cleanup season out here: the leaves come down, the last cuts get made, and the yards are set right before the cold arrives. A lawn kept in that rhythm holds its shape all winter and starts the spring already ahead. Southold, Peconic, Cutchogue, New Suffolk and Mattituck make up the working ground.
