Pascack Brook runs low and clear through Woodcliff Lake in the fall, and the yards along it fill with oak and beech leaf faster than anyone can keep up with. Tjb Landscaping Services keeps up with it, pulling leaves off the turf and out of the wall lines and beds so the grass goes into winter with air and light. Through the growing months it is the standard rotation: mowing on schedule, trimming close to walls, posts and the base of every tree, edges cut sharp along drives and walks. Lots out here are generous and wooded, which makes a tidy border worth more than it looks. A well-kept lawn in this part of the Pascack Valley is mostly a matter of showing up and finishing the corners.
