Culture NotesThis rhododendron is easy to grow in the Pacific Northwest. Plant it in rich well-drained or sandy soil in a location with full sun to light or open shade. Rhododendrons are shallow-rooted plants requiring regular watering during dry weather. Faded flowers can be removed to give a cleaner look and new growth can be pinched to help make young plants bushier. Adult root weevils can chew on their leaves, but this is less of a problem on plants that receive more light and regular watering.
