From the upper end of Adams Street the Blue Hills stand out of the October haze, and the whole ridge turns over from green to rust in the space of two weeks. Thomas Healy Landscaping runs the fall through that stretch of Quincy — leaf cleanup, final mowing, edges cut back sharp, beds cleared before the ground gets cold. Autumn work is heavier than summer work and better in its own way: cool air, early dark, and a visible result at the end of every driveway. Between spring and fall the routine is straightforward mowing and trimming, which is what keeps a lawn ready for a hard winter. A yard put away clean in November is the surest sign that somebody looked after it.
