There is a week each November around Tompkins Corners when the last leaves come down and the first hard frost sets, and the year visibly hands itself over. Maple Leaf Associates Inc. works both sides of that week. Through the warm months it is mowing, trimming, edging and the two big cleanups that bracket the growing season; after the handover it is plowing driveways, opening walks and salting the shaded stretches that stay slick long after the road has dried. Doing both means knowing a property twice — where the turf thins, where the drainage runs, where the plow can safely stack snow without burying a bed that will need to come back in April. Same yards, same hands, all the way around.
