From Turner Ridge you can see a long way across Palermo in June — hayfields going silver in the wind, dark woodlots between them, and not much noise at all. OnlyLawns LLC does one thing on that landscape and does it steadily: mowing, trimming, edging, and the spring and fall cleanups that keep a rural yard from turning back into field. Properties out here run big and open, with grass that pushes hard through a wet stretch and slows right down come August. The satisfaction is in stripes lying even across an acre and the border held tight against the driveway. Palermo and neighboring China, Liberty, Freedom, Somerville and Windsor are within range.
