The Yellow River slips along south of town under a low tunnel of river birch, and the humidity it hands Snellville by mid-June is the reason mowing starts early here. Amaya Lawn Care LLC takes the first yards while the grass is still cool, cutting, edging along the drive, and running the trimmer where the deck cannot reach. By the time the heat stacks up, a whole street has been squared away. There is a plain satisfaction in the last pass of the blower, when the concrete goes back to gray and the green stands up on its own. Weekly and biweekly lawn care, house by house, across Snellville and its neighbors.
