Climate signals
- NMSU divides New Mexico vegetable planning into USDA zones 5a through 8b, aligned with the updated USDA hardiness map.
- Average last frost ranges from after May 29 in zone 5a to before February 28 in zone 8b.
- The NMSU table lists 126 to 267 frost-free days across New Mexico growing zones.
- Individual gardens can vary as much as 20 days from zone averages because of elevation, site exposure, or air drainage.
Planning notes
- Use NMSU's three hardiness-zone groups before choosing a planting date because one statewide New Mexico calendar hides major season-length differences.
- Direct-seed carrots and beans when local soil and weather are favorable, but transplant tomatoes and peppers where the source says tender crops need a head start.
- In colder zones with shorter frost-free periods, use the crop table's direct-seed and transplant columns before choosing long-season warm crops such as eggplant, okra, squash, and watermelon.
- In warmer zones, keep spring and fall windows visible for cool-season crops such as beets, broccoli, cabbage, lettuce, peas, radish, and spinach.
