Plant Double Knock Out® Roses in well-drained soil with full sun exposure. Space plants 3-4 feet apart for optimal air circulation. Water deeply once a week, allowing soil to dry between waterings. Fertilize in early spring with a balanced rose fertilizer. Prune in late winter or early spring to shape and remove dead wood. Protect from extreme cold with a layer of straw or burlap if necessary. Regularly check for pests and diseases, treating promptly if detected.
