The first true snow of December usually arrives overnight in Needham, and by morning the rails near Hersey are two dark lines drawn across a white field. Wilson Landscape is already moving by then — driveways plowed down to the pavement, walkways and steps shoveled out, salt and sand spread where the sun will not reach until noon. The rest of the year the same crew keeps the grass in order: regular mowing, sharp borders, trimming, and the cleanups that open spring and close autumn. Both halves of the work come down to one thing — leaving a place ready to be used.
