In May the old rail bed through Blackwood is a green tunnel, and the yards backing onto it lean into the same growth spurt. Greenscapes New Jersey spends that season on the mowing rounds — keeping the cutting height honest, keeping trim lines tight around fences and posts, keeping clippings from smothering what is underneath. Grass in this corner of Camden County grows fast and unevenly, hard in the sun and thin beneath the sweetgums, and the answer is simply showing up on schedule and reading each yard for what it needs. The payoff is a Saturday morning when somebody walks out with coffee and finds nothing left to do. That is the job, start to finish, all across Gloucester Township.
