September in Bayside arrives on a wind off Little Neck Bay — cooler than the calendar says, carrying a little salt up over the Cross Island and into the yards along the water. JB Landscaping Company works those blocks through the turn of the season, mowing while the grass still pushes, edging the walks, cutting back perennials and taking the first fall of leaves. Lawns near the shoreline ask for their own kind of care: sandy patches, wind-burned edges, a slope that drains toward the parkway. Getting one green and even all the way to the curb takes patience worth spending. From Bell Boulevard to the quiet streets behind Crocheron Park, the difference shows from the sidewalk.
