By late August the farm stands along Sound Avenue are stacked with corn and the sunflower fields have gone heavy-headed, and the lawns in between need cutting twice as often as anyone expects. AC Landscaping, LTD keeps that rhythm across Riverhead — mowing, trimming and edging on a schedule that bends to how fast the grass is actually growing. Mulch goes down in spring while the ground is still cool, hedges get shaped before the heat sets in, and leaves get hauled off once the north wind turns for good. The reward is visible from the road: a lawn that looks tended right up to the line where the field begins. Out here, where farmland runs to the property line, that edge is worth getting exactly right.
