Water: Narrowleaf vervain thrives in well-drained soils and prefers dry conditions, showcasing notable drought tolerance. It requires occasional watering, ideally weekly, to maintain vigor. Grown outdoors, narrowleaf vervain flourishes when soil moisture is managed to prevent waterlogging and support healthy root development.

Fertilize: For narrowleaf vervain, use balanced nutrition fertilizers to promote growth and flowering, applying a slow-release formula every 4-6 weeks during the growing season. Adjust feeding in fall and winter, fertilizing when soil is moist to avoid root burn, ensuring even distribution for optimal nutrient absorption.

Pruning: Narrowleaf vervain thrives with early spring pruning to promote new growth. Remove weak stems to improve airflow, and repeat light pruning in late spring for bloom enhancement. Regular pruning prevents legginess, encourages fullness, reduces disease risk, and requires clean tools and cuts above leaf nodes for best results.

Propagation: Narrowleaf vervain is a hardy perennial ideal for gardens, propagating through seeds that thrive in well-draining soil and full sun. Lightly covering seeds fosters germination, while proper spacing post-germination allows for nutrient access, resulting in lush, healthy plants.
