West of Englewood the land flattens toward the Hackensack, and by early fall the soil there still holds summer's warmth while the air has finally cooled — the window when new turf roots fastest. New Jersey Sod Company works that window: ground cleared and graded, fresh sod laid tight, seams closed, then mowing and lawn upkeep once the roots knit in. A bare or tired yard can change character in a single day, which is a rare thing in this trade. Watering it in and cutting it correctly through the first season is what makes the change stick. By the following June it reads as though the lawn was always there.
