By the second week of October the maples around Pine Island Pond have gone loud, and the lawns underneath them disappear a little more each day. Nelson Lawn & Home Services, LLC works those south-end streets straight through it — mowing while the grass is still growing, trimming the borders, and taking leaves off turf and bed until the green shows again. Earlier in the year it's the steady stuff: weekly cuts, sharp edges along the walk, clippings cleared off the drive. A yard that's been kept all season shows it in November, when it goes into the cold clean instead of buried. That's the reward, and it doesn't get old.
