West of the Parkway the town thins into pitch pine and sand, and late-summer evenings out there smell of warm resin long after the mowers have stopped. Professional Bamboo Landscapers LLC works those edge-of-the-pines properties, cutting, trimming and edging where turf meets a treeline forever trying to move in. Cleanups pull back the needle drop and the volunteer growth so a lawn can keep its outline. Grass that borders woods needs a firm boundary, and holding that boundary is most of the art. Standing back at the end of a yard and seeing exactly where the lawn begins is the good part of the day.
