By the middle of May, Clifton Park is a town of green — the ball fields at the Common, the wide lawns along Moe Road, the strip of grass every homeowner quietly measures against the neighbor's. PERFECT GREEN LAWN CARE INC works in that stretch of the year when grass grows faster than anyone can keep up with, and again in the softer weeks of September when it comes back thick after the summer heat. Weekly mowing, clean trim lines, beds edged, clippings cleared: the result should look effortless even though it never is. There is a quiet pride in backing out of a driveway and seeing the whole yard sitting level in the afternoon light. PERFECT GREEN serves Clifton Park, Halfmoon, Latham, Round Lake and Ballston Lake.
