Osmanthus fragrans, commonly known as sweet osmanthus, fragrant olive, or tea olive, is a species of flowering plant in the family Oleaceae. Native to Asia, it is widely cultivated for its fragrant flowers which bloom in autumn. It can grow as a shrub or small tree and is well-suited to subtropical climates.
Osmanthus fragrans thrives in bright, direct sunlight and prefers moderate temperatures. It requires regular watering but should not be waterlogged. The plant enjoys moderate humidity and should be protected from extreme cold. Pruning is necessary to maintain its shape and encourage healthy growth.
土壌
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Good drainage is essential to prevent root rot. A mix of garden soil, compost, and sand can provide the ideal growing medium.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable for Osmanthus fragrans. Fertilize the plant during the growing season, typically in spring and summer, to promote healthy growth and flowering.
植え替え
Repotting is necessary every 2-3 years or when the plant outgrows its container. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Gently remove the plant, trim any dead roots, and place it in the new pot with fresh soil.
伝搬
Osmanthus fragrans can be propagated 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 cuttings in a warm, humid environment until they root.
剪定
Pruning should be done after the flowering period. Remove any dead or diseased branches and shape the plant as desired. Regular pruning helps maintain the plant's form and encourages new growth.
毒性
Osmanthus fragrans is not known to be toxic to pets or humans. However, it is always advisable to keep plants out of reach of pets and children to prevent any accidental ingestion.
