When to Plant Garlic in New Mexico

Growing Garlic in New Mexico: Complete Guide

Garlic (Allium sativum) is a fall-planted crop — it goes in the ground a few weeks before the first fall frost and overwinters for harvest the following summer. Depending on your zone, New Mexico gardeners plant between September 20, 2026 (Zone 5a) and November 10, 2026 (Zone 8b).

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 240 days to maturity, Garlic 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.

Garlic requires full sun (6+ hours) and low to moderate moisture. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
