Regular watering is essential, especially during dry periods. This plant is best suited for outdoor growth in gardens or naturalized areas.Soil
Vernonia fasciculata prefers loamy soil that is well-draining yet retains moisture. The soil should be rich in organic matter to support healthy growth. Ensure the soil pH is slightly acidic to neutral for optimal results.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season to promote vigorous growth and flowering. Apply the fertilizer every 4-6 weeks, following the manufacturer's instructions.Repotting
