Temperature Requirements
This plant can tolerate a wide range of temperatures, but it grows best in temperatures between 15 and 25 degrees Celsius. It can survive occasional frosts, but prolonged exposure to freezing temperatures can harm it. It can be grown as a perennial in areas with milder winters, but it may be an annual in colder areas.
Soil Requirements
Mentha arvensis L. var. canadensis (L.) Kuntze grows best in loamy, well-drained soils that are rich in organic matter. It can also tolerate clay soils, but the soil must be broken up and amended with organic matter before planting. The pH of the soil should be between 6.0 and 7.5. The plant prefers slightly moist soil, but it can tolerate drought conditions once established.
Cultivation methods
Mentha arvensis L. var. canadensis (L.) Kuntze, commonly known as wild mint, can be easily grown at home. It thrives in fertile, well-draining soil with a pH range of 6.0 to 7.0. The plant requires a lot of sunlight, so choose a spot that receives at least six hours of direct sunlight per day. Wild mint can also grow well in partial shade.
Watering needs
Water the plant regularly to keep the soil moist but not waterlogged. Overwatering can cause root rot. The frequency of watering will depend on the weather conditions, soil type, and the size of your plant. During hot summer days, the plant will require more frequent watering than during the colder months.
Fertilization
To encourage healthy growth, you can fertilize your wild mint plant with a balanced fertilizer every two to three weeks. Too much fertilizer can harm the plant, so be careful not to overfertilize. A natural option is to use compost or well-decomposed manure, especially during the growing season.
Pruning
Pruning is necessary to keep your wild mint plant healthy and to encourage bushier growth. Pinch off the stems and leaves to one-third of the length to promote the growth of new leaves. Pruning can be done anytime during the growing season, but avoid pruning during the dormant season.
Propagation of Mentha arvensis L. var. canadensis (L.) Kuntze
Mentha arvensis L. var. canadensis (L.) Kuntze, commonly known as Canadian mint or corn mint, is a herbaceous perennial plant mainly used for its essential oil.
Propagation Methods
The plant can be propagated through several methods, including:
- Seed Propagation: This method involves planting seeds directly in the soil in spring or fall, on prepared soil. The optimal temperature for seed germination is around 20 to 25°C, and the seeds will take about two weeks to germinate.
- Division: Division is a common propagation method for perennials, including Mentha arvensis.

Divisions should be carried out in the spring or in early fall, making sure each section has a viable root system and several leafy stems.
- Cuttings: Stem cuttings can be taken from the plant in the early summer when the plant is producing new growth. Cuttings are usually around 4 to 6 inches long, with leaves removed from the lower half of the stem. They should be planted in a well-draining potting mix and kept moist until the roots are established.
- Rhizomes: Rhizomes are underground stems that send out shoots and roots. They can be dug up and separated into sections with several nodes. Each section can be planted in a new location, with the nodes facing upwards, on well-drained soil.
Overall, Mentha arvensis L. var. canadensis (L.) Kuntze is a relatively easy plant to propagate, providing an excellent opportunity for both experienced and beginner gardeners to enjoy growing and using this valuable herb.
