When to Plant Peppers in Yavapai County, AZ

Sweet peppers are warm-season crops producing fruits in a rainbow of colors. They turn from green to red, yellow, or orange as they ripen, increasing in sweetness.

Yavapai County, Arizona is in USDA Zone 7b. The average last spring frost is April 9 and the first fall frost is November 5, giving you a growing season of approximately 210 days.

At an elevation of 3,732 feet, Yavapai County receives approximately 14.2 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 101ยฐF, so Peppers may need afternoon shade and extra watering during peak heat.
