Up No Name, the creek runs cold under a ceiling of cottonwood and the light arrives in coins. Aspen Arborist keeps lawns in exactly that kind of shade around Glenwood Springs — the thin, root-crowded grass that wants a lighter mowing height and a patient hand with the trimmer. Autumn is the long push here, with leaves coming down in waves for weeks, and every pass clears the turf before it can be smothered. Come spring the same yards get raked out, aerated and fed so the grass can race the canopy for a few good weeks of open sun. It is quiet work under big trees, and it shows up later as a lawn that stays green in the places lawns usually give up.
