DETAILS

Care Instructions
Phormium tenax thrives in temperate climates with moderate temperatures. It prefers bright, direct sunlight and should be watered when the soil partially dries out. The plant can tolerate a range of humidity levels but does best in moderate humidity. Regular pruning helps maintain its shape and encourages new growth.
Soil
Phormium tenax prefers well-draining loamy soil. It can tolerate a range of soil types but does best in soil that retains some moisture without becoming waterlogged. Good drainage is essential to prevent root rot.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically in spring and summer, to promote healthy growth. Avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of flowers.
Repotting
Repot Phormium tenax when it outgrows its container, typically every 2-3 years. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh soil.
Propagation
Phormium tenax can be propagated by division. The best time to propagate is in spring. Carefully dig up the plant and separate the offsets from the main clump, ensuring each division has roots attached. Replant the divisions in well-draining soil and water thoroughly.
Pruning
Prune Phormium tenax to remove dead or damaged leaves and to maintain its shape. The best time to prune is in late winter or early spring before new growth begins. Use sharp, clean tools to make clean cuts close to the base of the plant.
Toxicity
Phormium tenax is not known to be toxic to pets or humans. However, the plant's leaves are tough and fibrous, which could pose a choking hazard if ingested in large quantities.
Additional
Phormium tenax is a versatile plant that can be used in a variety of landscape settings, from coastal gardens to urban environments. It is relatively low-maintenance and can tolerate wind and salt spray, making it suitable for coastal areas.
