Spanish moss hangs still in the live oaks on a Folkston afternoon, and the shade beneath them is the only cool thing for a mile. Waldron lawn service moves through that heat with mower and trimmer, cutting the sandy yards even, edging the walks, clearing the drive before rolling on to the next one. Summer rain comes hard and fast and the grass answers within days, so the route repeats and repeats. A yard done right holds its shape until the next visit, and that is the whole ambition.
