Growing, Harvesting and Storage

Mentha pulegioides grows best in well-drained, loamy soil that is rich in organic matter, with a pH range of 6.0 to 7.5, and requires full sun to partial shade for optimal growth.

It thrives in temperate climates with moderate rainfall, needing consistent moisture but not standing water, and benefits from regular watering during dry periods. To ensure healthy growth, regular weeding, pruning of dead or damaged leaves, and occasional fertilization with a balanced organic fertilizer can promote vigorous plant development. Harvesting is best done in late summer to early autumn when the essential oil content is highest, by cutting the stems just above the soil line with sharp scissors to avoid damaging the plant.

After harvesting, the leaves should be dried in a cool, dark, and well-ventilated area to preserve potency, then stored in airtight containers away from light and heat to maintain their medicinal properties.
