Growing & Maintenance Tips for Rhododendron cat. 'Henry's Red'
Rhododendron Henry's Red prefers acidic, organically rich, humusy soils that retain medium moisture and provide good drainage. It thrives in part shade, especially in sun-dappled areas, and can tolerate some morning sun with afternoon shade. Avoid planting near walnut family trees due to their toxic juglones. Ensure good drainage, as these plants dislike "wet feet," and consider raised beds in heavy clay soils. Mulch with wood chips, bark, or pine needles to retain moisture, and promptly clip off spent flower clusters after blooming to encourage healthy growth.
