By August the cottonwoods down along Cherry Creek have gone dusty and the high-plains sun has had its way with every unshaded thing. Colorado Roots Landscape and Irrigation LLC works against that dryness in Cherry Hills Village, keeping lawns mowed, edged and trimmed while building the turf that can take a hard month. Core aeration opens the ground, overseeding fills what the heat thinned, fertilization sends the roots down where the water actually is. The name is not decoration — a lawn on this side of the Front Range lives or dies below the surface. Seasonal cleanups bracket the year, and in between the grass simply holds, green on a street where green takes intention.
