April rain crosses the Passaic valley in sheets, and two days later every lawn in New Providence has gone three shades darker. NATURE'S CHOICE LAWN & LANDSCAPE LLC meets that surge — the season's opening cuts, trimming back to the fence lines, raking out whatever winter left behind. Grass on this valley floor comes on fast and does not wait, so timing beats effort nearly every week of spring. The first mow of a year is the one worth waiting for: a yard stops looking like it has been sleeping. From there it becomes a rhythm held all season, cut by cut, until the light gets short again.
