KD Landscaping tends the lawns and driveways of Clinton, Massachusetts — the tight brick streets stacked above the Nashua River, the hillside yards that tilt toward the long blue edge of the Wachusett Reservoir. Warm months are mowing and trimming: stripes laid straight across a small dooryard lawn, the edge along the front walk cut clean enough to read from the sidewalk. Come winter the work turns to plowing, a driveway opened before the kettle boils and the banks pushed well back off the apron so a car can swing out without guessing. There is a plain, physical pleasure in both — a yard that looks looked-after, a clear way out to the road, the weather handled before anyone in the house has to think about it.
