Saturday mornings off Rock Quarry Road sound like mowers three streets apart, bicycles on the sidewalk and somebody's radio through a garage door. JT Lawn Care is part of that soundtrack, moving house to house with mowing, edging, string trimming and a clean blow-down of the concrete. Nothing about it is complicated, which is precisely why doing it well matters — a mailbox trimmed close, a sidewalk edge that runs straight, no clippings tracked into anybody's entryway. Yard cleanups take care of the leaves and limbs that gather between visits. By noon the block looks like somebody cares about it, and in a Stockbridge neighborhood that is contagious.
