Plant Care & Growing Tips

Growing Walla Walla Sweet Onion seeds successfully requires attention to a few key environmental factors. These onions are a long-day variety, meaning they need 14-16 hours of sunlight daily during bulb formation. Choose a location in your garden that receives full sun, ideally 6+ hours of direct sunlight per day. Prepare your soil by ensuring it is well-draining, loose, and rich in organic matter. A soil pH between 6.0 and 7.0 is ideal for optimal growth. You can amend heavy clay soils with compost and sand, or enrich sandy soils with compost to improve water retention and nutrient availability. Proper soil preparation is crucial for developing large, sweet bulbs.

Sow your Walla Walla Sweet Onion seeds directly into the garden in late winter or early spring, about 4-6 weeks before the last expected frost. Plant seeds about 1/2 inch deep and 1 inch apart in rows that are 12-18 inches apart. Once seedlings emerge and are a few inches tall, thin them to 4-6 inches apart to allow ample space for bulb development. Consistent watering is vital, especially during dry periods. Aim for about 1 inch of water per week, either from rain or irrigation. Avoid overwatering, which can lead to rot, but do not let the soil dry out completely. Fertilize every few weeks with a balanced, all-purpose fertilizer, or one higher in phosphorus and potassium to encourage bulb growth. Keep the area around your onions weed-free, as weeds compete for nutrients and water. These overwintering onion seeds are quite hardy, thriving in USDA Zones 3-12. Harvest when the tops begin to yellow and fall over, typically 13-17 weeks after planting. Cure them in a warm, dry, well-ventilated area for a few weeks before storing.
