Culture Notes
This azalea 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. Azaleas are shallow-rooted plants requiring regular watering during dry weather. Faded flowers often drop off or are quickly covered by new growth. Almost no pruning is needed to keep azaleas looking good. Adult root weevils can chew on their leaves, but this is less of a problem on plants that receive more light and regular watering.
