The Central Savannah River Area runs on red clay and loblolly pine, and a lawn out here has to be coaxed rather than commanded. CSRA Landscaping mows, edges and trims across Thomson and the roads that thread out toward Dearing and Boneville, working the long green stretch of the growing season a week at a time. In August, when the heat sits heavy over McDuffie County and the pines let their needles go, beds get cleared and pine straw freshened so the ground still looks tended in the worst of the sun. There is a plain satisfaction in a yard that reads clean from the road — the mow lines straight, the trimmer stopped exactly where it should stop, the drive blown down to bare concrete. That is the whole of it, done again and again, house by house.
