Holly Pond sits on the Darien line where the tide slides in beneath the causeway, and the streets above it catch the salt breeze all summer long. Thomas J Costello Landscaping keeps lawns through that stretch — mowing, edging, string trimming, fertilizing, overseeding and seasonal cleanups, on a rhythm that never lets a yard get away from itself. When December arrives, so does the plow: driveways cleared, walkways shoveled, steps and entries salted ahead of the morning. Grass and snow ask for opposite things, but they reward the same habit, which is showing up when you said you would. The proof sits out front where the whole street can see it.
