Centaurea nervosa requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers moderate humidity levels. Water the plant when the soil partially dries out, ensuring it does not become waterlogged. Regular pruning helps maintain its shape and encourages blooming.Soil
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil has good drainage to prevent root rot. A mix of garden soil with some sand and organic matter works well.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically every 4-6 weeks, to promote healthy growth and flowering.Repotting
Repot Centaurea nervosa every 2-3 years or when it outgrows its current container. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, shake off excess soil, and place it in the new pot with fresh soil mix.Propagation
Propagate Centaurea nervosa through seeds or division. Sow seeds in early spring or divide mature plants in late spring or early autumn. Ensure the divisions have healthy roots and replant them immediately.Pruning
Prune the plant regularly to remove dead or damaged stems and to maintain its shape. Pruning after flowering can encourage a second bloom. Use clean, sharp tools to make clean cuts.Toxicity
Centaurea nervosa 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.Additional
