Everything green on this stretch of the Front Range is a negotiation with dry air. Castle Rock Sprinkler Service works that negotiation for homes around The Pinery, tending lawns and the watering that keeps them alive between the thin rains. Mornings start early, before the sun clears the ridge and begins pulling moisture straight out of the soil, and the season closes with the lines drained ahead of the first hard freeze. In between there is mowing, edging and trimming, plus the small adjustments that decide whether a yard reads even in August: a head turned two degrees, a dry corner finally reached. From this ground you can see the butte that gave Castle Rock its name, and there is pride in keeping the lawns beneath it deep and unbroken green.
