Keystone Fruit Marketing to start Walla Walla Sweet Onion season in June

GREENCASTLE, PA – MAY 11, 2026 — Keystone Fruit Marketing BB #:334262, a division of Progressive Produce BB #:113613, is gearing up for an early June start for the Walla Walla sweet onion season.

Grown in a unique region and cultivated by third-generation growers, Walla Walla sweet onions are known for their exceptional sweetness and consistent quality.

“One of the things that sets Walla Walla sweet onions apart is where and how they’re grown,” said Dan Borer, Keystone Sales and Commodity Manager. “From the region itself to the fact that growers produce their own seed, it all contributes to delivering one of the sweetest onions available.”

Market conditions are expected to remain steady, with key promotional opportunities around Independence Day and throughout July.

Keystone supports customers with customized promotional programs and a full range of pack styles, including cartons, RPCs, bins, and consumer packs.
