East Kingston keeps its scale: the Powwow River slipping past under the road, stone walls holding what is left of the hayfields, the old depot line running quiet through the trees. On new ground here — a fresh grade, a raw slope, a scar left by a septic job — DIY Hydroseed sprays a seed and mulch slurry that clings to the soil and holds it while the roots take. Ten days later the bare dirt carries a green haze; a few weeks after that it is lawn. Hydroseeding, new lawn establishment and overseeding of thin patches make up the work, mostly in the cool halves of spring and fall when seed does its best. Watching a hillside turn from brown to green never gets old.
