The 1990 USDA Plant Hardiness Zone Map for New Mexico was the official USDA zone reference for over two decades. It was based on average annual extreme minimum winter temperature data collected from 1974 to 1986. Use the table below to compare 1990 zones to the revised 2012 zones and the current 2023 zones.
