Saturday mornings at T.W. Briscoe Park, the walking loop fills before nine and half of Snellville seems to be outdoors at once. Carters expert lawn care services spends those hours a few streets over, mowing, edging and trimming so a yard is ready for whoever comes home at noon. Shrubs get shaped, beds get fresh mulch, and the driveway is blown clean before the truck rolls. It is ordinary work done on a rhythm — the same houses, the same week, the line at the curb holding straight. Lawn care for Snellville and the Gwinnett towns just past it.
