Half the yards in Winchester are terraced, cut into a hillside above a brook, and mowing them is as much about footing as it is about grass. T&Z lawn and Landscape works that ground — weekly cuts on the flats and the pitches alike, clean edges where lawn meets driveway, trimming along retaining walls and stair, mulch in the beds so the rain does not carry them off. Late August turns the valley dusty gold and the grass slows down, which is when feeding earns its keep. Cleanups in spring and again in fall bracket the whole run. Grass holding a steep bank is doing real work, and it earns the care it gets.
