Care Instructions
Centaurea aspera requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and can tolerate dry conditions. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. Maintain moderate humidity levels.Soil
The plant prefers well-draining loamy soil. Ensure the soil has good drainage to prevent waterlogging, which can lead to root rot. A mix of sand and organic matter can help improve soil structure.Fertilizer
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant during the growing season, typically in spring and summer, to promote healthy growth and flowering.Repotting
Repot Centaurea aspera every 2-3 years or when the plant outgrows its container. Choose a slightly larger pot with good drainage. Gently remove the plant from its current pot, shake off excess soil, and place it in the new pot with fresh soil mix.Propagation
Propagate Centaurea aspera through seeds or division. Sow seeds in early spring or divide the plant during its dormancy period. Ensure the new divisions have adequate roots and replant them in well-draining soil.Pruning
Prune the plant to remove dead or damaged stems and to maintain its shape. Pruning can be done in early spring before new growth begins. Use clean, sharp tools to make clean cuts.Toxicity
Centaurea aspera is not known to be toxic to pets or humans. However, its spiny nature can cause physical discomfort if handled without care.REVOLUTIONIZE YOUR PLANT CARE
