Fruits

Apples growing on branchWashington State is the leading producer of apples, pears and cherries (both conventional and organic) in the nation. The climate in central Washington coupled with adequate irrigation water make this a great environment for many temperate fruits. Other important fruits are juice and wine grapes, peaches/nectarines, and apricots, and berry production is also increasing. Western Washington has long been an important producer of strawberries, raspberries, and blueberries. Fruit crops are sold throughout the nation and exported overseas, as well as in local markets and fruit stands. Advances in horticulture and pest management have played important roles in keeping these crops economically viable and in demand by consumers.
