Blackberry keeps its old hedgerows, its oak lines and its farmhouse lawns that run wider than a city block. Shaw Labor and Landscape mows and maintains those yards through the long green middle of summer, when a week's growth can swallow the edge of a walk. It is honest work with a lot of walking in it: the trimmer along fence posts, the blower down the drive, the last look back to see whether the lines run true. August afternoons out here go heavy and still, and the payoff comes at the end of one, standing in the shade of a yard that finally looks the way its owner pictures it. Then the truck rolls on to the next.
