Late June in Stowe, and the valley beneath Mount Mansfield has gone the deep, unembarrassed green that only a Vermont summer manages. Sprout Gardening & Landscaping L.L.C. works in that green — lawn care through the long mowing weeks, the straight pass, the clean turn at the corner, the trimmed line where grass gives way to stone wall or gravel drive. There is a particular pleasure in the after: a dooryard on some hillside road above the West Branch, cut and edged and sitting square in its own light, holding that shape while the mountain does whatever it likes with the weather. Week after week they keep lawns in Stowe and the neighboring towns looking tended, right through to the morning the maples start to turn.
