Plant Care & Growing Tips

Successful cultivation of Walla Walla onion seeds begins with understanding their specific needs. These onions thrive in conditions that mimic their native environment, producing the sweetest and largest bulbs when properly cared for. Start your heirloom onion seeds indoors 8-10 weeks before the last frost date, or sow directly outdoors in early spring once the soil can be worked. Ensure the soil temperature is at least 50°F (10°C) for optimal germination. Plant seeds about 1/4 inch deep and 1 inch apart, thinning seedlings to 4-6 inches apart once they are established. The ‘Fresh’ type of these seeds indicates they are ready for planting.

Sunlight Requirements: Walla Walla onions require full sun, meaning at least 6-8 hours of direct sunlight per day. Choose a location in your garden that receives ample light throughout the growing season. Proper sunlight is crucial for bulb development and sweetness. For indoor starts, use grow lights to ensure seedlings receive sufficient light to prevent legginess. These sweet onion seeds perform best with consistent light exposure.

Watering & Soil: Maintain consistently moist soil, especially during the bulbing stage. Onions have shallow roots, so they benefit from regular, shallow watering. Avoid letting the soil dry out completely, but also ensure it is not waterlogged, which can lead to rot. The ideal soil for growing Walla Walla onions is well-draining, loose, and rich in organic matter. A slightly acidic to neutral pH (6.0-7.0) is preferred. Amend heavy clay soils with compost to improve drainage and aeration. Watering should be medium, as indicated by the product specifics.

Fertilization & Pests: Fertilize your onion plants every few weeks with a balanced fertilizer, switching to a higher phosphorus and potassium fertilizer once bulbs begin to form. Avoid high-nitrogen fertilizers during bulbing, as this promotes leaf growth at the expense of bulb development. Monitor for common onion pests like onion thrips and onion maggot, and treat organically if possible. Good air circulation and proper spacing can help prevent fungal diseases. This annual vegetable thrives with consistent feed.
