Plant Sunset Horizon Rose in a location with full sun exposure. Ensure well-draining soil, enriched with organic matter. Space plants about 2-3 feet apart for optimal air circulation. Water deeply once a week, allowing soil to dry slightly between waterings. Fertilize in early spring with a balanced rose fertilizer, and again in mid-summer. Prune in late winter or early spring, removing dead or weak stems and shaping the plant. Protect from pests and diseases with appropriate treatments as needed.
