Southeast of town the rimrock at Castlewood Canyon shows what a slope looks like after weather and water have had their say — layered, deliberate, nothing accidental about it. Artistic Landscaping & Waterfall Design LLC brings that eye to ordinary Castle Rock yards, where the distance between a mowed lawn and a composed one is mostly attention. Turf is cut to an even height, borders defined, beds kept from creeping, and the whole yard read as a picture instead of a chore. Spring up here is a slow argument between frost and green; work along with it and by June the ground looks intentional. That is the aim on every visit.
