Rhododendron rubiginosum (红棕杜鹃) is a rhododendron species native to Myanmar, and Sichuan, Xizang, and Yunnan in China, where it grows at altitudes of 2,800–3,600 m (9,200–11,800 ft). This evergreen shrub grows to 1–3 m (3.3–9.8 ft) in height, with leaves that are elliptic or elliptic-lanceolate or oblong-ovate, 3.5–8 by 1.3–3.5 cm in size. The flowers are pink, red, or pale purple.
How to keep Rhododendron Rubiginosum.
Water
Water your rhododendron rubiginosum using rainwater or melted snow, as tap water can be too alkaline. During periods of active growth and in the summer, increase the watering frequency. In the winter, however, reduce the amount of water given. Check the pH of the water regularly and consider adjusting it with vinegar if necessary. During the winter months, water your plants before noon. In the spring and fall, avoid watering at noon. Additionally, reduce watering during rainy seasons.
Pruning
Rhododendron rubiginosum is known for its striking flowers and evergreen leaves. To keep your plant healthy and well-shaped, prune it in early spring to remove any dead wood. Thinning the plant helps improve airflow, which in turn minimizes the risk of disease. Be careful not to prune too heavily, as this can lead to fewer blooms. Instead, perform light pruning after the plant has finished flowering to encourage bushier growth. Always use clean and sharp tools for pruning.
