There is an hour in June when New London is all green and hush — dew still holding above Williams Memorial Park, gulls high over the harbor, the day not yet warm. JJs Lawn Care starts in that hour. Mowing, trimming, edging and cleanup work carry them through the week's yards, the small city lots and the deeper ones that run back toward the trees. A lawn cut well has a look you can read from the sidewalk: even height, a clean line at the walk, clippings off the concrete. They hold New London yards to that from the first flush of spring growth to the last leaf-heavy weekend of autumn.
