A lawn in Epsom looks its best in the hour after the mower leaves it — the passes laid straight, the edge cut clean along the walk, the clippings carried off and the whole yard sitting up straighter than it did that morning. That is the work Envy Landscaping keeps to, here in the town where Routes 4 and 28 swing around the circle and the Suncook River slides quiet behind the trees. The ground lifts west toward Fort and McCoy, and the yards under it come in every shape: long roadside frontage out toward Gossville, shaded half-acres near Short Falls, small dooryards tucked beneath white pine. Mowing, trimming and edging, mulch laid dark around the beds, spring and fall cleanups that haul off the winter's litter and the maples' leaving — plain services, every one, and every one visible from the road when it is done right. The satisfaction of it holds about a week, which is exactly why the route comes around again.
