Roanoke Avenue in October is a tunnel of maples letting go all at once, and every lawn beneath them disappears by the weekend. CORTE LANDSCAPING & MANSORY CORP. handles the whole arc of that in Riverhead — the spring cleanup that opens the beds, the weekly mowing and trimming through summer, and the leaf removal that finally gives the grass its light back. Edges get recut so the mulch line stays where it belongs, week after week. Hedges get shaped before they lean out over the sidewalk. There is a real satisfaction in the after: a yard raked bare and breathing, with a truckload of leaves headed out of town.
