The Pascack Valley Line runs through Emerson a dozen times a morning, and the lawns beside the tracks get measured by everyone looking out a window. Jlm4seasons landscaping keeps that view honest — cut on schedule, edged along the sidewalk, beds mulched dark so the plantings read from a distance. Work opens in March hauling off everything winter left, runs through the mowing months, and closes in November with the leaves. Small borough, short streets, a lot of neighbors who notice. The reward is a lawn that looks the same on a Tuesday as it does on a Saturday.
