By September the stone walls around the old North Kingstown farm fields go warm along the top and cool in their shade, and the grass slows down enough to be shaped rather than chased. Lawn King RI works that stretch of the calendar with mower, edger and trimmer, following the walls into the corners where the machine cannot quite reach. Cleanups come next — leaves off the beds, the lawn opened back up to whatever light is left. None of it is complicated; it is only done all the way to the edges. A yard that has been kept all summer wears the fall beautifully.
