The Walla Walla Onion Seeds produce an acceptably mild crop from a spring planting in areas with more severe winters. Try to protect it over the winter with light mulch. We’ve had mixed results with this method. Worth experimenting if you crave a mild onion.

Sowing Outdoors- Early to mid-spring when soil temperature reaches at least 55 ºF. Sow 1-3 seeds per inch, thin to 2-6” apart. The larger the bulb size, the more space.

Harvest- Stop watering a week before harvesting. Pull out when necks soften and start to fall over. Cure them in the sun for a few days then finish drying them out of direct sunlight, in a warm area, and in single layer so air can circulate around them until the neck is dry. Store in a cool, dark place with 35-40ºF temperatures and 65-70% humidity.
