Above the floodplain the ground lifts into sandhills, and the longleaf up there rattles in a way the bottomland never does. Autumn on this stretch of the river is the season of long light and slowing growth, when a lawn asks for less cutting and more attention to its edges. GreenRoots Lawn Care LLC. works that shift: mowing when the grass earns it, trimming out around posts and beds, blowing needles and cuttings off drives and walkways. A yard finished on a cool October afternoon will hold its shape for weeks. Homes along the river corridor and in the towns nearby are within reach.
