Leonia shows what its old street trees are worth every November, when the canopy comes down all at once and the lawns vanish underneath it. Tj Storff Landscaping Inc handles that season's cleanups and the spring one that answers it, along with mowing, edging and trimming from the first flush of green onward. Shade this deep changes the way a lawn grows — slower, thinner in places, and greener later into the fall than out in open country. The job is reading each yard for what it wants and holding to the schedule that suits it. Grass raked clear and cut even, with the big trees still standing over it, is this borough at its best.
