Closter keeps its canopy, and that changes the job — lawns here grow in dapple, thinner under the big limbs, lush out where the early June sun gets through. Timberline Tree & Landscape Inc. reads a yard that way, cutting a little higher in the shade, keeping the blades sharp so the grass tears less, working the mower pattern around the trunks instead of fighting them. The result on a bright morning is a lawn that looks whole under the trees rather than patchy beneath them. Through the season the crew keeps the schedule steady and clears the yard down before winter. Lawn care for Closter and the neighboring Northern Valley towns.
