Plainville still keeps its stone walls and its open ground out toward Plainridge, where meadow grass has gone tawny by the end of August. Harrington Landscaping brings that same countryside neatness to the yards in town: mowing at a height the grass can carry through a dry spell, trimming out the fence lines, cutting the edges along walks, cleaning beds and hauling away what comes out of them. Late-summer lawns in this part of Massachusetts want patience above all — cut high, cut often, and the color returns with the September rain. A finished yard has a stillness to it.
