Down along the Cocheco, the stand at Hanson Pines holds the cool air until mid-morning, and Rochester lawns stay wet with dew longer than you would expect. Advanced Lawn care LLC starts anyway, mowing and trimming through neighborhoods on both banks of the river. Riverside ground grows heavy, so an even cut takes a sharp blade and sometimes a second pass. Autumn brings the cleanup work — leaves off the grass and out of the beds before the first freeze locks them in place. There is a plain pleasure in leaving a street where every lawn on the route looks finished.
