North of the city, at Penacook, the Contoocook comes in over its falls and joins the Merrimack, and the old village streets run down toward the water. Oasis Landscaping covers that end of Concord and the rest of it — mowing and trimming on schedule, mulching, shaping shrubs, and running full cleanups in spring and fall. When the season flips, out come the plows and shovels for driveways, walkways and steps, with sand and salt where the ice sets in, so a dooryard stays usable no matter what fell overnight. Green months and white months ask for different tools and the same habit: show up, finish, sweep up behind yourself. Properties kept that way rarely look like they need anything.
