Dendrobium thyrsiflorum, commonly known as the Pineapple Orchid, is a species of orchid in the family Orchidaceae. It is native to the wet tropical climates of Southeast Asia, particularly in regions like India, Thailand, and Vietnam. This plant is a pseudobulbous epiphyte, meaning it grows on other plants and has thickened stems that store water. It produces beautiful, fragrant flowers in dense clusters, typically during the spring. The plant undergoes a dormancy period of about 2 months during the cooler season.
Dendrobium thyrsiflorum requires bright, indirect light and thrives in moderate temperatures. It prefers high humidity and should be watered regularly to keep the soil evenly moist. During its dormancy period, reduce watering but do not let the plant dry out completely. Ensure good air circulation to prevent fungal infections.
土壤
This orchid prefers a well-draining, loamy soil mix that retains some moisture but does not become waterlogged. A mix of bark, perlite, and sphagnum moss works well. 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. Dilute the fertilizer to half the recommended strength to avoid over-fertilization.
换盆
Repot Dendrobium thyrsiflorum every 2-3 years or when the potting medium breaks down. Repot in the spring after flowering. Gently remove the old medium from the roots, trim any dead roots, and place the plant in fresh orchid mix. Ensure the new pot has good drainage.
传播
Propagate this orchid through division. Divide the plant during repotting by separating the pseudobulbs, ensuring each division has at least 3-4 healthy pseudobulbs. Plant the divisions in fresh orchid mix and care for them as mature plants.
修剪
Prune Dendrobium thyrsiflorum after flowering by removing spent flower spikes and any dead or yellowing leaves. This helps the plant conserve energy and encourages new growth. Use sterilized pruning shears to prevent the spread of disease.
毒性
Dendrobium thyrsiflorum is not known to be toxic to pets or humans. However, it is always best to keep plants out of reach of pets and children to prevent any accidental ingestion.
额外的
Ensure the plant has good air circulation to prevent fungal infections. Mist the plant regularly to maintain high humidity, especially in dry indoor environments. Avoid placing the plant in direct sunlight as it can scorch the leaves.
