This is a long season variety that requires 14 hours of sunlight per day to set bulbs. Onions prefer fertile soil with an abundance of regular watering for best growth. Sow in early spring as soon as the soil can be worked, and plant successive crops every few weeks for continuous supply.

Pull when skins have developed on bulbs and tops are falling over. Allow bulbs to cure for storage by drying on top of soil for a few days. Walla Walla will store for no more than two months.
