Planting and Growing Instructions

• Days to Maturity: 90-120 days, depending on growing conditions.

• Planting Depth: Sow seeds 1/4 inch deep.

• Plant Spacing: Space plants 4-6 inches apart in rows spaced 12-18 inches apart.

• Days to Germination: Seeds typically germinate in 7-12 days under ideal conditions.

• Start Indoors or Direct Sow? For best results, start seeds indoors 8-10 weeks before the last frost date in your area, then transplant outdoors when soil is workable. In mild climates, you can also sow seeds directly outdoors in early spring or late summer for a fall harvest.

• Sunlight Requirements: Full sun is essential for healthy, vigorous growth and the development of sweet, flavorful bulbs.

Growing Tips

• Soil Preparation: Walla Walla onions thrive in loose, fertile, well-drained soil with a neutral pH of 6.0-7.0. Amend the soil with compost or aged manure to boost nutrients and moisture retention.

• Watering: Keep the soil consistently moist but not soggy, especially during bulb development. Regular watering is crucial for sweet, tender onions.

• Fertilization: Apply a balanced fertilizer high in phosphorus and potassium during early growth, avoiding excessive nitrogen to prevent overgrowth of greens at the expense of bulbs.

• Weed Management: Mulch around plants to retain moisture and suppress weeds, which compete for nutrients.

• Harvesting: When the tops of the onions begin to flop over, it’s time to harvest. Cure bulbs in a warm, dry location for 1-2 weeks before storing.
