In July the Warner River runs low and warm, and the grass along the dooryards grows an inch overnight — that's the week Tyler Lawn Care is out earliest, mowers running before the heat stacks up against the flank of Mount Kearsarge. This is lawn care in a town of brick storefronts and long sloping yards: mowing kept to a steady weekly rhythm, trimming and edging until the line between lawn and walkway is clean enough to sight down, mulch laid dark and even around the beds. Come October, when the maples of the Mink Hills let go all at once, the same work turns to rakes and tarps and leaf hauling, yard by yard from Warner out toward Bradford, Sutton, Webster and Contoocook. The pleasure of it is in the after — a property that reads cared-for from the road, holding its shape and its color right through the season.
