Wrightsville keeps its courthouse square and its shade trees, and the lots around it have the deep, unhurried yards that middle Georgia towns were laid out with. Southern Lawns Of Georgia works those properties — mowing, edging, string trimming, and clearing the leaves and limbs that follow every fall and every storm. Johnson County soil runs sandy and the grass takes off after a warm rain, so the schedule matters as much as the machine. A finished yard here has the walk lines showing again, the fence corners cut in, and the concrete blown clean. Late afternoon, with the heat letting go, is when the whole square looks the way it should.
