Snow on the old mill pond up in the north of Marshfield turns everything into one flat white page, and the only marks on it are tire tracks and a plow line. Ohlund Landscape makes some of those marks, out clearing driveways and walkways while the storm is still coming down. The rest of the year runs greener — mowing on a weekly rhythm, edges cut along walks and drives, string trimming, and cleanups when the season turns at either end. Working a town this old means working around stone walls, root-bound maples and yards that were never laid out square. That is half the appeal.
