When to Plant Mint in New Mexico

Growing Mint in New Mexico: Complete Guide

Mint (Mentha spicata) is a crop that grows best when sown directly in the garden. In New Mexico, the right time to direct sow is around Sunday, March 8, 2026, once soil temperatures are consistently warm enough for germination.

Because New Mexico stretches across 8 USDA hardiness zones (5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 90 days to maturity, Mint fits comfortably within New Mexico's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Mint requires partial shade to full sun and regular (keep moist) moisture. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
