On a clear Magnolia evening the western sky keeps a little of Philadelphia's glow in it long after the sun is gone, and the cicadas take over the block. J & O Landscaping Services LLC spends those long days out in the heat, with mowing, edging along curbs and walks, string trimming, mulching beds, and the spring and fall cleanups that bookend a Camden County growing season. Borough lots are compact, which means every mistake is visible and so is every clean edge. So the lines get cut true and the clippings get blown off the sidewalk before the truck moves. Small yards, one after another, are the whole of the work here.
