The name carries most of the idea. A Haverhill lawn can be small, sloped and hemmed in by fence, hydrant and driveway apron, and what makes it look right is the line — cut even, trimmed close, edged so the grass stops exactly where the concrete starts. Kleen Kutz Lawn Care LLC holds to that standard right through the growing season, from the first cut once the river valley dries out to the last one before the ground goes hard. The Merrimack keeps this city humid and green well into September, which means the grass never really lets up, and neither does the route. Pull away from a finished yard, look back once, and the edges should be the first thing you see.
