White Dawn Climbing Rose thrives in well-drained, fertile soil with full sun exposure. Ensure regular watering, especially during dry periods, to keep the soil consistently moist but not waterlogged. Prune in late winter or early spring to promote vigorous growth and remove dead or weak wood. Support the climbing canes with a trellis or similar structure to encourage upward growth. Fertilize in early spring with a balanced rose fertilizer to enhance flowering.
