Walla Walla Sweet Onion
Growing Walla Walla Sweet Onion
‘Walla Walla’ is an open-pollinated onion prized for its enormous flattened bulbs and famously sweet flavor. Golden skins surround mild, juicy flesh, creating a classic sweet onion that performs best when grown under long-day conditions despite its day-neutral tendencies.
Start ‘Walla Walla’ indoors for transplanting or sow directly where conditions allow. Plant seeds about ¼ inch deep and space plants 12 to 18 inches apart. Grow in full sun. This cold-tolerant variety is also well suited to containers.
Ready to harvest in about 110 days, lift the large bulbs once they reach full maturity and cure them according to their intended use.
Huge, sweet, and mild, ‘Walla Walla’ is excellent for slicing, salads, sandwiches, grilling, roasting, and everyday cooking.
