September afternoons down toward the Newington line, where Piper Brook slips along behind the yards, carry a slant of gold that makes even an ordinary lawn look like something worth photographing. Chenail LLC works that stretch of West Hartford in the season when the grass finally relaxes — cool nights, steady growth, the last strong month before the leaves take over. Cuts get taken a touch higher, edges get re-established after a summer of creep, and the beds get cleaned out so autumn arrives to a tidy property instead of a tired one. Then come the leaves, and the work changes to hauling and blowing until the turf can breathe again. A yard put to bed properly in October is already halfway to a good spring.
