Troy is a city of bluestone curbs and brick walks, and lawn work here means cutting right up to hard edges without chewing them. Lewis Lawn Care and Masonry mows, trims and edges on that principle, with spring and fall cleanups to bracket the green season. Winter puts the same trucks behind a plow — driveways cleared, paths shoveled to the door, salt on the stone before it turns slick. There is a rhythm to a place where grass ends and stonework begins, and the line between them ought to be sharp. Holding that line, week to week, is the craft of it.
