Water: Vietnamese coriander thrives in humid environments, requires weekly watering to maintain moisture, and does not tolerate drought. As an herbaceous perennial, it benefits from consistent moisture whether indoors or outdoors, with its growth cycle closely linked to water availability.

Fertilize: Vietnamese coriander thrives with balanced nutrition fertilizers. Apply a diluted liquid formula every two weeks during spring to late summer, and reduce to once a month in cooler months. Always water thoroughly before and after, adjusting application based on seasonal growth for optimal health.

Pruning: Vietnamese coriander is a flavorful herb that benefits from pruning in early to late spring. Focus on removing dead or crowded stems to promote healthy, bushy growth. Regular trimming encourages denser foliage, maintains shape, and improves air circulation, reducing the risk of fungal diseases.

Propagation: Vietnamese coriander thrives in moist, well-drained soil and partial shade. Propagate using healthy stem cuttings below a node, ensuring several leaves remain. Keep cuttings moist but not waterlogged. Root development takes weeks, after which new plants can be potted. Regular trimming promotes bushy growth.

Repotting: Repot vietnamese coriander every 2-3 years in spring, using a medium-sized pot with good drainage. Keep vietnamese coriander warm and moist post-repotting, avoiding sogginess. A well-lit area without direct sunlight promotes healthy growth for this moisture-loving herb.
