Eastern Washington is renowned for its apple orchards, producing the majority of the U.S. apple supply.

Because of its perfect climate—warm days and chilly nights—and rich volcanic soil, Eastern Washington is one of the most productive apple-growing regions in the US. Apples such as Red Delicious, Granny Smith, and Honeycrisp are grown in this area, especially in the Wenatchee and Yakima Valleys. Large-scale orchards flourish in this usually arid region thanks to irrigation from the Columbia River. More than 60% of the nation's apples are produced in Washington State, which also exports apples all over the world. The economy and agricultural character of the area are greatly influenced by the industry.
