How to Grow and Care for Corsican Mint Lawn

Unlike most varieties of mint, which grow aggressively and invasively, Corsican mint is difficult to grow. It's a low-growing plant with tiny rounded glossy green leaves on short stalks, rarely growing more than a quarter of an inch tall. 

The tiny leaves are perfect for growing around stepping stones or walkways, where they release a fragrant scent. It's used to manufacture green crème de menthe. Corsican mint's pungent scent repels brassica-eating pests.

Planting mint near entrances or in pots can prevent mice and other pests. Traditional uses include dyspepsia treatment and antiseptics.

Coriscan Mint Care.

Corsican mint needs more attention and care than most garden types of mint, which can become invasive with little effort. Corsican mint is a strong-scented and flavorful culinary mint. Grow this and other mints in containers to control their spread. A pot outside the kitchen door or on the terrace is also helpful. Plant in the ground to cover a sparsely vegetated area of the landscape or a difficult-to-maintain slope or bank, but keep an eye out for spread.

Warning

Corsican mint is a southeastern invasive plant. Consult your local extension office about planting Corsican mint.

Light

This mint grows in the sun or shade. In hotter climates, some shade may be preferable.

Soil

Corsican mint thrives on well-drained soil that contains some organic matter to retain moisture. It can also grow in acidic soil.

Water

Too much water will cause root rot in Corsican mint. It needs regular watering and isn't drought-tolerant, so maintaining this balance can be challenging. Before watering, let the soil surface dry out.

Humidity and temperature

Corsican mint is temperature sensitive and only naturalizes in U.S. growing zones 7 to 11. If it becomes too damp, its leaves may turn black and slimy.

Propagating

Dividing Corsican mint is easy. In favorable climates, it self-seeds and spreads, becoming invasive. Once established, plants can be divided and shared.

How to Grow Corsican Mint from Seed

Corsican mint seeds can be sown 4 to 6 weeks before the last frost date. If sowing seeds outdoors, the soil should be 65 degrees F. Lightly press seeds into the soil and spray. 7–14 days should be enough.

Overwintering

This plant can't overwinter in zones below 7. In winter, you can grow it in containers. Light it indirectly near a window.
