On a summer evening the long green in front of the brick houses along South Main Street in Geneva holds the last light of the day. Tru Lawn Care and Landscaping, LLC keeps that kind of ground: mowing, trimming, edging beds and walkways, with a spring opening and a leaf clearing once October gets going. Old lawns in this city come with shade, surface roots and a hundred corners a mower will never reach, which is where the trimmer earns its keep. What makes a street like that look right is the edge, a clean line where grass stops and stone begins. Doing that block after block is a fine way to spend a season.
