It thrives in wet tropical climates and is often found along coastal areas. The tree is known for its glossy, dark green leaves and fragrant white flowers. It produces a nut that yields tamanu oil, which is used in traditional medicine and cosmetics.
Calophyllum inophyllum requires bright, direct sunlight and thrives in warm, humid conditions. It prefers consistently wet soil and should be watered regularly to maintain moisture. The tree grows best in moderate to high temperatures and high humidity. Regular pruning is necessary to maintain its shape and health.
土壌
This tree prefers well-draining loamy soil that retains moisture but does not become waterlogged. It can tolerate a range of soil types but thrives best in nutrient-rich soil with good drainage. Adding organic matter can help improve soil quality.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the tree during the growing season to promote healthy growth. Follow the manufacturer's instructions for application rates and frequency.
植え替え
Repot young trees every 2-3 years to accommodate their growing root system. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Gently remove the tree from its current pot, loosen the roots, and place it in the new pot with fresh soil.
