Field Mint Plant Care

Field Mint (Mentha arvensis) belongs to the Lamiaceae family within the Mentha genus. Field Mint is native to the temperate regions of Europe and western and central Asia, east to the Himalaya and eastern Siberia, and North America. Field Mint is also known as Wild Mint, Corn Mint.

Field Mint displays a spreading, mat-forming herb growth habit, reaching up to 1 ft tall with a spread of approximately 1 ft. Field Mint produces small, lilac to white flowers in terminal spikes.

Leaf size: approximately 2 inches.

Mentha arvensis requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Field Mint thrives in full sun to partial shade.

Mentha arvensis grows best at temperatures of 65–75°F. Field Mint prefers humidity levels of 40–60%.

Well-draining, fertile soil with a neutral pH. Good drainage is essential for Field Mint to prevent waterlogging, which leads to root rot and fungal issues.

Feed Field Mint every 2 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Divide and repot every 2-3 years. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Field Mint can be propagated through division, stem cuttings, seeds. Similar propagation techniques also apply to spearmint plant care, which shares the same genus.
