At six in the morning the dew still lies heavy on Rowley's lawns and the birds have the town to themselves. Nature's Way Land Care Inc works that hour, cutting while the grass stands up straight, trimming close around the pines and the posts, blowing the walks clean behind the machine. The mowing height shifts with the month — taller through August heat, closer when the cool air comes back — because a lawn tells you what it needs if you look at it. The season is bracketed by a rake-out in April and another in November. By eight the yard is finished, and the day belongs to whoever lives there.
