From the hill at Greene Valley you can see the whole spread of it — Naperville's tree canopy one way, farm squares the other, weather visible a long time before it arrives. J&B Landscape Solutions, Inc works both halves of that view's year: mowing, trimming, edging, mulch and cleanups while the ground is soft, plowing and salting once it is not. The DuPage growing season is generous and short-tempered, and the winter has opinions of its own. Crews learn a property's grade — where water runs, where a plow can turn, which corner of turf the shade keeps thin. Done right, a place looks cared for in July and passable at six on a January morning.
