By late August a Sharpsburg afternoon builds its own weather — thunderheads stacking up west of Highway 154, the air going green and still before the first drops hit the pavement. Impact Turf Solutions works ahead of that clock, mowing and trimming Coweta County lawns in the hours when the grass is dry enough to cut right. Bermuda and fescue both grow hard here through the long southern summer, so the work becomes a rhythm of steady cuts, sharp edges and clippings taken off the walks and drives. Shrubs get shaped back from the windows; beds get their lines redrawn where the rain has washed them soft. When the storm finally rolls through, it falls on a yard already put in order.
