Walla Walla County is a valley of two farming systems. The 2022 Census counted 894 farms working 713,416 acres at an average of 798 acres each, roughly double the state average, and county farms sold $778.6 million of agricultural products, up 48 percent from 2017. Wheat for grain is the largest crop by area at 219,473 acres, but only about 12 percent of county farmland is irrigated, so the dryland wheat ground east of the city and the irrigated valley floor need very different equipment.
The valley's signature crop is the Walla Walla Sweet Onion, grown by approximately 12 growers on about 400 acres, planted in September and hand-harvested the following summer under Federal Marketing Order 956. The Walla Walla Valley AVA, designated in 1984, supports 120 or more wineries planted mainly to Cabernet Sauvignon, Merlot, and Syrah.
