June mornings in Burlington's South End start early — the Pine Street corridor still cool, Oakledge quiet, dew heavy enough to leave a track behind you. Sharp Edge Lawn Care works while that lasts, mowing straight lines and then cutting the borders along sidewalks and driveways until the boundary reads like a drawn line. That edge is the whole difference between a lawn that has been mowed and a lawn that has been finished. Trimming goes in close around posts, steps and tree trunks; cleanups at both ends of the season handle the leftovers. Look back down a street at the end of a run and the sharpness is visible from the corner.
