How to Grow Vietnam Spearmint from Seeds:

Seed Starting: Start Vietnam Spearmint seeds indoors or directly sow them outdoors after the last frost date in your area. Plant the seeds in well-draining soil, covering them lightly with a thin layer of soil. Keep the soil consistently moist until germination, which typically occurs within 7-14 days.

Transplanting: Once the seedlings have developed a few sets of true leaves, transplant them to their permanent location. Choose a sunny to partially shaded spot with fertile, moist soil. Spearmint can spread rapidly, so consider planting it in containers or using barriers to control its growth.

Growing Conditions: Vietnam Spearmint thrives in rich, moist soil with good drainage. Water the plants regularly, keeping the soil evenly moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weed growth.

Maintenance: Spearmint is a vigorous grower and may require regular pruning to keep it in check. Trim back the stems regularly to encourage bushy growth and prevent the plant from becoming too leggy. Remove any flower buds as they appear to prevent the plant from self-seeding.

Harvesting Time: Vietnam Spearmint can be harvested once the plants have become established and have developed a sufficient amount of foliage. Harvest the leaves as needed throughout the growing season, typically starting in mid to late summer. For the best flavor, harvest the leaves in the morning when the essential oils are most concentrated.
