First light in Swampscott arrives straight out of the ocean, and for a few minutes King's Beach and every east-facing lawn behind it are the same shade of pink. New Dawn Landscaping favors those early hours — mowers running while the dew is still down, trimming and edging finished before the day gets loud. Grass grows hard in the damp air off the water here and rewards a schedule kept faithfully. Spring and fall cleanups bookend the mowing season, clearing what the storms and the maples leave in the beds. A lawn that looks brand new by breakfast is a good way to start anybody's day.
