Spring reaches Mary Elmer Lake ahead of most of the county — dogwood first, then redbud, then a green that seems to arrive overnight. Green Harmony Landscaping LLC opens the season there with cleanups and settles into the steady rhythm of mowing, edging and trimming through the long Bridgeton summer. A lawn under old shade wants a different hand than one in full sun, and by June the difference is easy to read. What keeps the work interesting is that no two properties on the same street ask for quite the same thing.
