April along Webb Bridge Road belongs to the dogwoods, white all through the understory, and then a week of pine pollen turns every windshield the color of cornmeal. Gibson Landscape Services, LLC. works straight through it: first mows of the year, beds cut in with a fresh edge, mulch spread dark against the new green, shrubs trimmed back off the walkways. Alpharetta lawns wake up unevenly — warm-season grass out in the open, fescue hanging on in the shade — and each wants a different hand. A good day here ends with a driveway swept bare and a mow line that runs true from one property corner to the other.
