Walpole keeps a green at the center of its village and brick storefronts around it, and the seasons turn there in plain view. Connecticut Valley Yard Works follows that turn with mowing, trimming, edging and the cleanups of spring and fall, then trades the mower for the plow once the ground hardens. Winter work is driveways and lots cut open, walks shoveled, sand laid where the streets tip toward the river. Summer work is the cut held to a straight line and the beds edged crisp against the lawn. Two trades, one address book, and the same yards looked after the whole way around.
