Around the North Haven Green the maples run copper in October and stand bare by Thanksgiving, and the year turns over from mowing to plowing without much ceremony. Pisani Landscaping keeps that two-part rhythm for houses and businesses here — lawns cut and tended through the warm stretch, snow moved off drives and walkways once the cold settles in for good. On a winter morning the payoff is simple: pavement showing black again, a path to the front door, a car that can get out on time. In July it is the smell of fresh cut grass drifting down a street where every yard looks looked-after.
