How to Plant Wild Mint (Mentha Arvensis)
Wild mint, also known as corn mint, is often grown for use as a flavor in food, teas and salads. It is also used medicinally as an antiseptic and to help with digestion. It is even planted to deter rodents from the garden. Wild mint is usually planted from seeds, which are available for purchase from nurseries and online. The easiest way to plant wild mint seeds is directly out in the garden. Wild mint is hardy in U.S. Department of Agriculture zones 4 to 8, and since it spreads quickly, it can become invasive if not controlled.
1.Plant wild mint seeds in the fall or cool them the refrigerator for two to three months before planting in the spring. If the seed packet states that the seeds are ready to plant, skip this step.
2.Plant seeds in an area that receives partial to full sun. A sunny location will yield more essential oils if you are growing wild mint for that purpose.
3.Plant wild mint seeds in soil that has a pH level between 5.8 and 6.5, if possible. Wild mint prefers these slightly acidic soil conditions, but will grow in other types of soil as well. If desired, adjust the soil by testing the soil's pH with a home soil testing kit and add sulfur or limestone, or another material that raises or lowers the acidity levels in soil. How much you should apply depends on your results. Follow the manufacturer directions.
4.Scatter the seeds lightly on top of the soil and water with approximately 1/2 inch of water. When the plants reach 6 or more inches tall, thin out the plants so that one healthy plant is located every 12 to 15 inches. Consider only keeping a couple plants since wild mint multiplies quickly.
Tips & Warnings
The fruit of wild mint is toxic and can be fatal if too much is digested. The fruit looks like a grape, so be careful if you have children.
