The Cochituate Rail Trail carries walkers and bikes past the back edges of a hundred Framingham yards, and it is a good place to see who keeps theirs sharp. Green Landscape Lawn Service is behind a fair share of them — mowing on rhythm, string-trimming the fence lines, edging until the border is a line and not a suggestion. Spring cleanup and mulch set the year up; autumn's leaf work closes it out. When the wind off the lake turns cold, plowing and shoveling take over, with treatment down before anyone steps out for the mail. It is the same promise in July and January: come when we said, do it right.
