Heat Zones, Plant Health, and the AHS Heat Zone Map

With tools like the USDA plant hardiness map, we typically only consider low winter temperatures as the primary metric by which we determine which plants to sow. However, we might benefit from incorporating summer temperature trends, like the information presented in the American Horticultural Society’s heat zone map, into our planting decisions. With summer temperatures spiking to record highs due to a changing climate, the impact of high heat on plant life is becoming increasingly relevant to growers.
