A Saturday afternoon along Pinebrook Boulevard sounds like mowers answering each other across the backyards, with the water at Twin Lakes flat and bright through the trees. Sosa Brothers Landscaping LLC is out in that chorus most weeks of the growing season, mowing, edging, running the string trimmer through the tight spots, then clearing the drive so it is bare when the truck pulls away. Lawns on this side of the city run wide and sloped, and keeping the stripes honest across them is its own kind of pride. In the shoulder months the work turns to cleanups, hauling off what came down and giving the turf room to breathe. The result is plain enough from the sidewalk: a straight edge, an even cut, nothing left behind.
