Every June the Front Range sends one hailstorm that shreds a lawn down to stems in nine minutes. Colorado Lawn Clinic answers that, and the slower troubles too: thin patches, weeds moving in, turf worn along the walking routes near the Community Ditch trail. Mowing, feeding, aerating, tidying up in spring and fall — the ordinary schedule that puts a yard back together. Grass out here recovers well if it gets the right things in the right week. Watching green close over a bare spot never gets old.
