Frequently Asked Questions About Walla Walla Onions

  1. How do you grow Walla Walla onion seeds? To grow Walla Walla onions from seed, start by planting the seeds indoors 8-10 weeks before the last frost date, or sow them directly in the garden 6-8 weeks prior to the final spring frost. Plant the seeds about 0.25 inch deep in well-drained, fertile soil with a pH of 6.0-7.0. Ensure the location receives full sun. Thin the seedlings to 3-6 inches apart as they grow. Keep the soil consistently moist and fertilize as needed. Walla Walla onions are long-day onions, requiring 14-15 hours of daylight to form bulbs.
  2. What month should I start onion seeds? The best time to start onion seeds depends on your growing zone and whether you’re planting long-day or short-day onions. For Walla Walla onions, a long-day variety, start seeds indoors around late winter to early spring, typically 8-10 weeks before the last frost date. This usually falls around January to February in many northern climates.
  3. Which onion is sweeter, Walla Walla or Vidalia? Both Walla Walla and Vidalia onions are known for their sweetness, but Vidalia onions are often regarded as slightly sweeter.
