Oaks hold their leaves longer than anything else up here, rattling brown into November long after the maples have given up. Twin Oaks Landscaping LLC does its heaviest work in that stretch, raking, blowing and hauling until the turf is clear and the beds are cut back for winter. The rest of the year runs on mowing, edging and trimming, week by week through a Roscommon summer that never lasts as long as anyone wants. Mulch gets refreshed, borders get sharpened, and the grass is cut at a height that can take the sandy ground and the sudden dry spells. By the first real snowfall, the yards are already put away.
