Expert tips
The key tip
Cornus hongkongensis appreciates light partial shade and cool but well-drained soil. It's a subtropical dogwood: too much shade slows flowering, too much heat/drought stresses the leaves.
The common mistake
Planting it in full midday sun weakens it; leaves scorch and flowers don't appear.
The pro's trick
Site it in the afternoon shade of a larger tree (east-northeast facing is ideal).
Care
Exposure
Hong Kong dogwood thrives in partial shade, ideally under dappled light. It tolerates moderate direct sun but prefers to be protected from the strongest afternoon rays. An east or northeast-facing exposure suits it particularly well.
Watering
Keep the soil regularly moist, especially during the active growing season (spring-summer). Reduce watering in winter but don't let the soil dry out completely. Avoid excess water which could cause root rot.
Soil type
This plant appreciates rich, well-structured soil that is slightly acidic to neutral. Enrich the substrate with compost or potting soil to improve moisture retention and fertility. Good drainage remains essential to prevent root suffocation.
Pruning and training
Prune lightly after flowering to maintain a harmonious and balanced shape. Remove dead, diseased or crossing branches. This also promotes air circulation at the plant's heart and encourages better flowering the following year.
Fertilizing
Apply a balanced fertilizer in spring at the start of growth. A second application can be made in early summer if the plant shows vigorous growth. Prefer moderate and regular feeding to overfeeding.
Diseases and pests
Hong Kong dogwood can be susceptible to scale insects and aphids in warm, confined conditions. Check foliage regularly and treat quickly if infestation occurs. Powdery mildew may appear in cases of excessive humidity combined with poor air circulation.
Did you know?
The genus Cornus, to which Hong Kong dogwood belongs, has been revered since antiquity in Asia for its bright red fruits and traditional medicinal properties. In China, Cornus hongkongensis is valued not only for its ornamental appeal but also for its berries used in traditional medicine, symbolizing longevity and harmony.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
