Air off the Great South Bay comes in salted and soft, and Babylon lawns grow thick under it from May straight through September. GrowinGreen Landscape & Design mows and trims those yards — the tight village lots behind the picket fences, the deeper properties out toward the creeks and canals where the tide shows in the ditch. Late-afternoon work has its own pleasure: the mower quiet at last, the trimmer line following every fence post and mailbox, gulls going over toward the ferry docks. Come autumn the oaks around Argyle Lake shed steadily, and clearing them out keeps a lawn breathing into winter. What the crew leaves behind is a yard that looks finished from the sidewalk and stays that way until the next visit.
