North Caldwell's oaks drop late and drop hard, and by the first week of November the lawns along Mountain Avenue are ankle-deep. Green Crest Land Care clears them off — blowing, collecting, hauling away — so the grass goes into winter breathing instead of smothered. The rest of the year runs on the weekly rhythm: mowing, trimming, edging along walks and stone walls, beds weeded and mulched, borders held to a line. In a ridge borough with old trees and long sightlines, the difference a kept lawn makes is visible from the road. Quiet work, obvious result.
