The Rosa Westerland prefers well-drained soil that is rich in organic matter. It needs full sun exposure for at least 6 hours a day to bloom properly. The plant requires regular watering, especially during dry periods. It is recommended to water deeply once a week rather than lightly every day. Fertilize the plant in early spring with a balanced fertilizer. Prune the plant in late winter or early spring to remove dead or damaged wood and shape the plant. The Rosa Westerland is hardy in USDA zones 5-9.
