Where the Canaseraga runs in to meet the Genesee the ground goes flat and rich, and the lawns on that bottom land come on fast once the spring water drops. Spallina Materials Inc. mows across Mount Morris and the farm roads toward Sonyea and Groveland, trimming close to posts and outbuildings and cutting the drive edges back square. Mulch and bed cleanups happen in the spring mud, and the leaf work runs late into fall on the big open properties where the wind keeps moving things around. Cut, trimmed, blown clean — three steps, and a place looks finished. Valley soil grows a heavy lawn, and there is pride in staying even with it.
