Oregon has one of the most diverse farm economies in the country, with more than 200 different commodities grown across its valleys, high desert, and coastal lowlands. Agriculture is a cornerstone of the state's rural communities and a major export sector, so understanding regional conditions matters for both commercial growers and home gardeners.

Farming in Oregon

Greenhouse and nursery products rank among Oregon's most valuable agricultural sectors, alongside cattle and calves, hay, and dairy. The fertile Willamette Valley in the west is known worldwide for grass seed, and the state produces the large majority of the nation's hazelnuts. Other important crops include wheat, wine grapes, pears, berries, potatoes, onions, mint, hops, and Christmas trees, while cattle and sheep grazing dominate the drier country east of the Cascades. This mix of irrigated row crops, tree fruit and nuts, specialty seed, and rangeland livestock gives Oregon farming a highly varied character.

Climate and growing conditions

Oregon's climate splits sharply at the Cascade Range: western valleys and the coast have mild, wet winters and dry, warm summers with a long growing season, while eastern Oregon is a colder, more arid high desert with hot days, cool nights, and a shorter frost-free period. Growing seasons range from well over 200 days in the Willamette Valley to far fewer in the mountains and high plateau. A gardener in Oregon may encounter USDA hardiness zones from about 4 in the coldest interior highlands to 9 along the milder southern coast.
