Late May near Watnong Brook, and everything is growing at once — the grass fastest of all. Fernandez Landscape & Masonry LLC mows through that surge in Morris Plains, holding height and line steady, edging along the walks and trimming tight to fence posts and foundations. A yard is mostly geometry once the work is finished: a straight border, a clean strip of pavement, a lawn that reads as one piece. Cleanups in spring and fall clear the ground for the season on either side. The good part is the before-and-after, every single week.
