Arizona Planting Zones & Schedule

Across Arizona, USDA growing zones span from Zone 5b to Zone 10a, depending on elevation and region. Higher areas in the northeast, such as Flagstaff and the White Mountains, fall within Zones 5b to 7b, where cooler conditions favor hardy crops like peas, carrots, and leafy greens.

Meanwhile, the southern and western parts of the state, home to cities like Phoenix, Tucson, and Yuma, sit in Zones 8a to 10a. These regions have hot, extended growing seasons perfect for sun-loving vegetables such as tomatoes, peppers, and melons.
