HOOD RIVER — Back in 1913, small growers in the Hood River Valley decided to join ranks, forming one of the nation’s oldest agricultural cooperatives. A few years later, below-freezing temperatures swept across the valley, causing apple trees to split — but the pear trees held firm and have since dominated hillsides.

Transitions continued for Diamond Fruit Growers, collectively owned and managed. In 1971, Diamond opened its cavernous Odell packing house and, as preferences shifted in the early 1980s, closed its cannery in downtown Hood River. Today, Diamond must contend with demands from behemoth grocers, rising costs and an aging labor force that’s only getting smaller.
