Take Route 128 southeast out of Mount Kisco toward Armonk in October and the hedgerows go copper along the fence lines while the fields hold their last green. Prestige Landscape LLC works that country in both directions — mowing, trimming, edging and mulching through the warm months, leaf cleanups when the ridges let go, then plowing, hand work on the walks and salt once the shoulders go white. Long approaches and stone-lined drives make winter a matter of geometry as much as horsepower. The result people remember is the simplest one: everything cleared, everything squared, nothing left in the way. Mount Kisco, Armonk, Bedford, North Castle and Chappaqua are all inside the range.
