September may be the finest month for a Chesterfield lawn — heat off, rain back, grass growing like it means it right up to the edge of Brandenburg Park. Tone Setter Landscape Services cuts, trims and keeps grounds through that stretch, and carries the same properties into the plowing season. There is something worth chasing in a mowing pattern that lines up with the street and stays lined up week after week until it looks effortless. Lakeplain lawns are broad and level here, which hides nothing and rewards a straight line. Winter work is blunter and just as exact: open the drive, clear the walk, be gone before the day starts.
