Down at the Rancocas the water is tidal, and on an early-autumn morning the creek runs one way, then thinks about it, then runs the other. Knob Creek Landscaping starts its days near that hour, when the dew is heavy and the first cut throws a clean, wet stripe across the grass. The warm half of the year is mowing, edging, trimming and cleanups; the cold half is plow work, cleared drives, shoveled walks and de-icing on the north-facing slopes that never see sun. Sandy South Jersey soil drains fast and dries faster, which changes how a lawn should be cut and when. Getting that right is most of the craft, and the result shows from the road.
