Down in Pine Brook the land lies flat as a table and the Passaic takes its slow bend through the meadows, so the grass there comes in thick and needs a steady hand. Discovery Landscape Design handles that lawn work across Montville — regular mowing, clean edges along the walks, string trimming around posts and beds. On a humid August morning the cut grass smells like the river bottom itself, sweet and heavy. Cleanups bracket the season on either end, clearing the ground in spring and stripping the leaves off in November. What stays with a homeowner is not the machine noise; it is pulling in to a yard that looks settled.
