DETAILS

Care Instructions
Trimezia coerulea thrives in bright, indirect light and prefers moderate temperatures. It should be watered when the soil partially dries out, and it enjoys a humid environment. Regular pruning helps maintain its shape and encourages new growth.
Soil
This plant prefers well-draining loamy soil. It is important to ensure that the soil does not remain waterlogged, as this can lead to root rot. A mix of garden soil with some sand and organic matter works well.
Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable for Trimezia coerulea. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and flowering.
Repotting
Repot Trimezia coerulea every 2-3 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage, and carefully transfer the plant, ensuring the rhizomes are not damaged.
Propagation
Trimezia coerulea can be propagated by dividing the rhizomes. This is best done during the dormant period. Carefully separate the rhizomes and plant them in individual pots with well-draining soil.
Pruning
Pruning is necessary to remove dead or damaged leaves and to maintain the plant's shape. Prune after the flowering period to encourage new growth and more blooms in the next season.
Toxicity
Trimezia coerulea 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 accidental ingestion.
