West of town the land begins to tilt toward the hills, and plenty of yards out that way are more slope, rock and root than level ground. Top Notch Tree & Excavating LLC takes those on: mowing the banks, trimming what a machine can't reach, edging, mulching the beds that hold the grade, and seeding the thin stretches until the turf finally knits. Autumn means leaves off and beds cut back; spring means the winter's mess cleared and a first cut that wakes everything up. At the end of a long day there is that look back down the yard — awkward ground made even and green — which is the whole reason to do it. Ramsey, Oakland, Mahwah, Franklin Lakes and Wyckoff.
