Pittosporum tenuifolium, commonly known as kohuhu or black matipo, is a small evergreen tree native to New Zealand. It belongs to the family Pittosporaceae and is known for its glossy, dark green leaves and small, fragrant flowers. This plant thrives in subtropical climates and is often used in hedges and as an ornamental tree.
Pittosporum tenuifolium requires bright, indirect light and moderate temperatures. It prefers a humid environment and should be watered when the soil partially dries out. Regular pruning helps maintain its shape and encourages healthy growth.
土壌
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil has good drainage to prevent waterlogging, which can lead to root rot.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize during the growing season, typically in spring and summer, to support healthy growth.
植え替え
Repot Pittosporum tenuifolium every 2-3 years or when it outgrows its current container. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in spring.
伝搬
Propagate this plant through semi-hardwood cuttings taken in late summer. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the soil moist and provide indirect light until roots develop.
剪定
Prune Pittosporum tenuifolium in late winter or early spring to maintain its shape and remove any dead or damaged branches. Regular pruning encourages bushier growth and helps maintain the desired size.
毒性
Pittosporum tenuifolium 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 avoid any potential issues.
