On a July evening the light hangs behind Crown Mountain, the heat finally lets go, and fireflies rise out of a freshly cut lawn as if the grass were exhaling. Duffey Landscaping works toward that hour around Dahlonega — mowing, trimming, edging, hedge and shrub shaping, and every clipping blown off the concrete before the truck pulls away. Growth in these foothills is relentless through the warm months and rewards anyone who stays on schedule. A yard that still looks cut on day six is the goal, and that comes from sharp blades and honest height, not luck. Little of the work is complicated; all of it is deliberate.
