Augusta sits on the fall line, where Piedmont red clay gives way to sand, and a lawn's whole character is settled down there before anything shows on top. After the first warm rain of April the color comes up quickly — centipede first, Bermuda close behind — and then the season stretches on for months. Holding that green means regular mowing at the right height, trimming to the bed lines, edging the concrete and clearing whatever the cut leaves behind. Green is not one color in Georgia; it is a dozen, shifting with heat and rain and how a yard has been treated. Getting a lawn to hold its own shade of it is the work.
