The West Fork of the North Branch runs quiet along Northfield's western side, and the ground near it holds its cool well past a May sunrise. D Cruz landscaping LLC starts there, in grass still bent with dew, the deck set high for the first hard flush of the season. Trimming follows the fence lines, edging follows the walks, and the clippings go where clippings belong instead of onto the pavement. Aeration, seeding and mulch come later, once the river bottom dries out and the turf wants room to breathe. By the time the light climbs over the trees, a yard that was shaggy at six is squared away and green.
