Planting & Care
Start Walla Walla Sweet Onion seeds indoors 8-10 weeks before the last frost date. Sow seeds 1/4 inch deep in a seed-starting mix and keep consistently moist at around 70°F. Once seedlings are sturdy and danger of frost has passed, harden them off and transplant outdoors, spacing 4-6 inches apart in rows 12-18 inches apart. Choose a sunny location with well-drained soil rich in organic matter. Keep the area weed-free and water regularly, especially during dry spells. Stop watering as bulbs mature to help them cure. Harvest when tops begin to yellow and fall over, then cure bulbs in a dry, airy place before storing.
