Give this valley a warm rain in late spring and the grass turns feral — the Ramapo River runs high, the ground stays soft for days, and a lawn can put on inches while you are at work. That is the creature Lawn Monster, LLC is named for and the one it handles. Mowing on a schedule that doesn't slip, edging, trimming, cleanups, mulch, and seed and feed to thicken the turf until weeds have nowhere left to sit. There is real satisfaction in walking a yard that was shin-deep at nine and dead level by eleven, clippings off the walk, the whole thing suddenly calm. Ramsey, Mahwah, Oakland, Franklin Lakes and Allendale, every week, rain or shine.
