By late October the pecan rows outside Louisville have gone gold and brittle, and the wind comes through them like it has somewhere to be. Campbell's Lawn & Landscape LLC keeps yards in order through that turn — mowing while there is still growth in the blades, then leaf and debris cleanup, trimming, and edging that holds its shape once the grass slows down. Fall in the Georgia sandhills is a gentle thing; the light goes long and amber and the work gets quieter. A yard raked clean under a bare pecan is one of the better sights of the season. The company covers Louisville and neighbors like Davisboro, Bartow, Wadley and Avera.
