Verbena grows best in a sunny location with at least six hours of direct sunlight daily. Choose well-draining soil to prevent root rot and water the plant when the top layer of soil feels dry. Although verbena can tolerate some drought once established, regular watering helps it produce healthy flowers. Remove faded blooms to encourage continuous flowering throughout the growing season. Applying a balanced fertilizer occasionally can support growth, while proper spacing improves airflow and reduces the risk of fungal diseases.
