Killington's growing season is short and it knows it — the mountain holds snow into May and takes it back by October, so the grass has to make its case fast. Grassdogs Lawncare and Snowplowing LLC works that narrow window with steady mowing, trimming around ledge, posts and plantings, edging that keeps walks and drives defined, and cleanups at both ends of the green months. Up near Kent Pond and along the roads off the mountain, lawns run thin over rock, and cutting them well means knowing where the soil actually is. A tight, even lawn in a place this vertical reads like an argument won. Killington, Mendon, Bridgewater, Pittsfield and the nearby towns are their territory.
