Greentree sits on Pinelands sand, soil that drains almost as fast as the sky can fill it, so a lawn here is really a conversation about water. RBL LAWN CARE, LLC has that conversation every week from April on — mowing at a height that shades its own roots, feeding on a schedule the sand can hold, weed control before bare spots invite trouble. Edges are cut in along drives and walks, the trimmer taken around lamp posts and beds, and cleanups clear the way in spring and close it out in fall. July evenings out toward Black Run come with that heavy Burlington County air and the smell of hot pine. The lawns still standing in late August are the ones that got the small things right all season.
