On a July Saturday, Route 537 fills with cars headed for Great Adventure, and two streets back Jackson goes quiet again. That is where T&J LANDSCAPING LLC. spends the day — mowing, trimming, edging, mulch worked in around the foundation beds. Fall brings the other half of the year: leaves off the lawns and out of the corners before the wind packs them into the fence lines. The township runs from farm fields to pine woods to cul-de-sacs, and a yard in each asks for its own handling. The trailer pulls away, the lines are straight, and nobody has to think about the lawn again until next week.
