Dendrobium nobile, commonly known as the noble dendrobium, is a species of orchid native to the Himalayas, Assam, Nepal, Bhutan, and parts of China. It is a pseudobulbous epiphyte or lithophyte that thrives in subtropical climates. This plant is known for its beautiful, fragrant flowers that bloom in clusters along the stems. It has a dormancy period during the winter months.
Dendrobium nobile requires bright, indirect light and moderate temperatures. It thrives in high humidity and should be watered regularly, allowing the soil to dry out partially between waterings. During its dormancy period, reduce watering and keep the plant in a cooler environment.
土壌
This orchid prefers a well-draining, loamy soil mix. A mix specifically designed for orchids, which often includes bark, perlite, and sphagnum moss, is ideal. Good drainage is essential to prevent root rot.
肥料
Use a balanced orchid fertilizer with a nutrient composition of 20-20-20. Fertilize every two weeks during the growing season and reduce feeding during the dormancy period.
植え替え
Repot Dendrobium nobile every 2-3 years or when the plant outgrows its pot. Repot in the spring after the blooming period. Use a fresh orchid mix and ensure the new pot has good drainage.
伝搬
Propagate Dendrobium nobile through division. Divide the plant during repotting by separating the pseudobulbs, ensuring each division has at least three healthy pseudobulbs. Plant the divisions in fresh orchid mix.
剪定
Prune Dendrobium nobile after the blooming period. Remove any dead or yellowing leaves and spent flower stems. This helps to maintain the plant's health and encourages new growth.
毒性
Dendrobium nobile is not toxic to pets or humans. However, it is always best to keep plants out of reach of pets and children to avoid any potential issues.
追加
Ensure good air circulation around the plant to prevent fungal infections. During the growing season, mist the plant regularly to maintain high humidity levels. Avoid overwatering, as this can lead to root rot.
