By July the Bermuda and zoysia along Killian Hill Road grow faster than anyone can keep up with, and the heat sits on Lilburn like a hand. Trimlawn Landscape Services works that season for the line — the straight, deliberate edge where turf stops and concrete begins, recut until a driveway looks drawn rather than mown. Weekly mowing, trimming around fence posts and mailboxes, and clearing the walks follow behind it. There is a real satisfaction in standing at the curb afterward with nothing left out of place. Lilburn's ridges and the streets that fall away from them get that same attention, week after week, all the way through the growing season.
