Organic Onion, Walla Walla

Soil & Water: Onions prefer loose, fertile, friable, well-drained soil with plenty of added organic matter. Their shallow root system is sensitive to fluctuations in water. Mulch to conserve water and control weeds.

Planting & Growing: In warm climates, sow seed in late fall for a spring harvest. Walla Walla is very cold hardy in long- and intermediate-day areas where temperatures do not drop below -10°F. Performs well as a spring-sown onion in the northwest. If transplanting, cut the seedlings back to 3" high before setting out in soil which is 55°F minimum.

Harvesting & Storage: Harvest when the tops fall over: In cool, humid areas when all tops have fallen; in cool, dry areas when half the tops have fallen; and in warm areas when a third of the tops have fallen. Loosen the soil around the onion with a fork and gently pull it from the soil. Short keeper; not for winter storage.
