Care Instructions
Acmella caulirhiza requires bright, direct sunlight for optimal growth. It thrives in warm, humid conditions and prefers consistently moist soil. Regular watering is essential to keep the soil wet. The plant can be grown both indoors and outdoors, provided it receives adequate light and warmth.Soil
The plant prefers loamy soil that retains moisture well. Good drainage is essential to prevent waterlogging, which can harm the roots. A soil mix that includes organic matter will help maintain the necessary moisture levels.Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable for Acmella caulirhiza. Fertilize the plant every few weeks during the growing season to support its nutrient needs.Repotting
Repotting should be done annually or when the plant outgrows its current pot. Choose a slightly larger pot with good drainage. Carefully transfer the plant to the new pot, ensuring the roots are not damaged.Propagation
Acmella caulirhiza can be propagated through seeds or cuttings. For seed propagation, sow the seeds in a moist, well-draining soil mix and keep them in a warm, bright location. For cuttings, take a healthy stem cutting and place it in water or moist soil until roots develop.Pruning
Pruning is necessary to maintain the plant's shape and encourage bushier growth. Trim back any leggy or overgrown stems, and remove any dead or damaged leaves. Pruning can be done throughout the growing season as needed.Toxicity
Acmella caulirhiza is not toxic to pets or humans. However, its numbing effect when chewed can be quite strong, so it should be used with caution.REVOLUTIONIZE YOUR PLANT CARE
