Downing Park fills up on the first warm Saturday of the year, and the whole of Yorktown Heights seems to decide at once that the grass season has started. Androsko Landscape Contractors is out ahead of that, opening beds, raking off what winter left, and putting a first clean cut on lawns still waking up. From there it's a weekly rhythm through the summer — mowing, edging the walks, trimming around trees and posts so the yard holds a sharp outline. Come November the leaves get gathered and taken away, and the turf goes into the cold with nothing smothering it. A lawn that looks intentional from the sidewalk is the whole ambition, week after week.
