Up in Rainbow the Farmington drops over the dam in a long white sheet, and you can hear it from the yards on the ridge above. Roots & Stone Property Services LLC keeps those yards through the growing months — mowing, edging, trimming, and the heavy clearing of spring and autumn that nobody wants to do twice. That part of Windsor is uneven ground, part sand and part ledge, and a lawn on a pitch needs a different plan than one sitting flat. Working that out property by property is the interesting half of the job. By midsummer, the difference between a yard on the schedule and one off it can be read from the street without slowing down.
