South Philadelphia keeps its green in small, fierce squares — a strip beside the steps, a back patch behind a Passyunk Avenue kitchen, a corner lot that somebody decided would be grass. BEST CHOICE LANDSCAPING & MASONRY treats those little rectangles the way a larger yard gets treated anywhere else: mowed even, edged sharp along the concrete, trimmed close to the fence line, the clippings gone before dinner. On an August evening when the block cools off and the folding chairs come out, a freshly cut patch smells like something worth sitting beside. Spring and fall bring the cleanups, the mulch, the hedges brought back into shape. The work runs from Girard Estate and Pennsport across to Grays Ferry and down toward the stadium blocks.
