Expert tips
The key tip
Peppermint spreads quickly and easily takes over its neighbors. Isolate it in a pot sunk into the ground or a fenced area.
The common mistake
Letting it sprawl freely in the garden: it ends up dominating the entire area within a few years.
The pro's trick
Regularly harvest young stems for tea or cooking: this makes the plant bushier and keeps the flavor at its best.
Care
Watering
Keep the soil constantly moist, without saturation. During the growing period (spring-summer), water regularly 2 to 3 times a week. Reduce watering in winter. Mulching naturally retains moisture.
Light exposure
Place the peppermint in partial shade or full sun for better foliage and aromatic production. It tolerates partial shade, but aim for at least 4 to 6 hours of daily sunlight to optimize flavors.
Pruning and harvesting
Pinch young stems regularly to encourage branching. Harvest leaves and stems as needed during growth. In late summer, cut the plant back to half its height to stimulate dense regrowth and prepare for overwintering.
Fertilizer
Apply a balanced liquid fertilizer every 3 to 4 weeks in spring and summer. Rich compost worked into the soil at the start of the season is often sufficient. Avoid excess nitrogen, which would dilute the aroma.
Soil and drainage
Peppermint prefers fertile, organic-rich soil that is well-drained. Improve poor soil with compost or quality potting mix. Good drainage prevents root rot in case of prolonged moisture.
Diseases and pests
Watch for rust, a fungus common on Lamiaceae in humid conditions; ensure good air circulation. Spider mites and aphids may appear in dry indoor environments. Regular misting and good air circulation prevent most problems.
Did you know?
Peppermint is a natural hybrid between water mint and spearmint, discovered in England in the 17th century. Its intense and refreshing aroma made it so popular that it became one of the most widely cultivated aromatic plants in the world, used for centuries in herbal tea, cooking, and traditional medicine.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
