Most of these neighborhoods were cotton and pasture inside living memory, and the county still shows it in the way a subdivision suddenly gives way to a treeline. Gwinnett Lawns works that patchwork out of Dacula — mowing, edging, trimming and blow-off across yards that run from quarter-acre to wide open. Growth in this county is relentless from May through September, and cool weather brings leaves rather than relief. The work amounts to a standing appointment with the ground. Done right, nobody notices anything except that the place looks right every single week.
