Long Island holds green longer than people expect: privet stays furnished into December, and the turf around Whitney Pond Park keeps a dull emerald under frost. Evergreen lawn care service works toward exactly that, a lawn strong in October that still means something in January. Cutting on rotation, trimming, fertilizing and overseeding through the cool weeks when roots do their real work, leaves lifted before they mat down and smother the crown. Manhasset yards sit under big old trees, which makes the seeding pass more judgment than routine. The reward arrives in March, when the grass wakes up already thick.
