Medicinal & Aromatic· Mentha × piperita

Peppermint Growing Guide

Hybrid mint (M. aquatica × M. spicata) grown commercially for menthol-rich essential oil. India and the US (Pacific Northwest, Midwest) are top producers. Menthol is used in pharmaceuticals, oral care, confectionery, and aromatherapy. Distinct from spearmint — higher menthol content (40-50%) makes it the preferred medicinal species.

How Long Does Peppermint Take to Grow?

Peppermint is typically ready to harvest about 90 days after planting.

Growing Tips

Harvest at early bloom (10% flower) for peak menthol content; cut 5 cm above ground and wilt in swath 24-48 hours before distillation.

Rotate fields every 3-4 years — Verticillium wilt builds up in continuous peppermint and there are no resistant cultivars. Flame or propane flaming after harvest sterilizes surface inoculum.

Contain in beds or use root barriers — peppermint spreads aggressively by stolons and will overtake adjacent crops within one season.
