Late August in Wilsonville has a gold to it — fields going tawny, the light longer and lower across the mowed strips. Lajoie Brothers Lawn Care works Thompson lawns through that stretch and every week on either side of it: mowing on a set schedule, trimming along fences and stone walls, edging where turf meets drive, cleanups in spring and again once the leaves are down. Grass slows in the dry weeks and jumps after rain, and the schedule bends to that rather than fighting it. There is pride in a lawn that looks the same good way every time the truck pulls out of it. That evenness, week after week, is really the whole trade.
