September in Mattapan still runs warm, and the long back lots off Blue Hill Avenue give up one more flush of growth before the season turns. Yard-Aid keeps those Boston yards on rhythm — mowing, string trimming, edging along the walk, and the cleanups that clear a property in spring and again once the leaves let go. Deep lots mean real square footage, and the gap between a mown yard and a maintained one shows first at the fence line. Feeding and overseeding go down in the fall so that April does not start from behind. By the last cut of the year the whole place looks properly put away.
