Drive south out of Newnan toward Turin and Moreland in October and the county turns the color of dry hay, with the pines holding the only green. Newnan Coweta Lawn Care keeps a route through all of it: the season's last mows, leaves cleared off bermuda and fescue alike, beds cut back for the cool months. Cooler mornings make for good work — the red clay firms up underfoot and a crisp edge stays crisp for a week. Autumn is also when the aeration cores and the seed go down for next year's lawn. Coweta County is the name on the truck and the ground under it.
