At the north end of Upper Saddle River the land starts to lift toward the Ramapo hills, and on a July evening the light comes in low and gold across the lawns. Northern River Landscaping likes that hour — mowers cooling, the last trim finished, a yard sitting quiet and even with the smell of cut grass still on the air. Through the season it is steady work: weekly mowing, borders kept true along the walks, spring and fall cleanups that bookend the green. Then the cold turns everything into logistics — plowing the drives, clearing the walks, salting ahead of the refreeze that locks it all down by dark. The lawns don't change; only what's lying on them does.
