How to start Walla Walla Onions from seeds
Growing Walla Walla onions from seed is a great way to ensure a bountiful harvest of these sweet and juicy onions. Here are some steps to get started:
- Choose a good location: Walla Walla onions require full sun and well-drained soil. Choose a location in your garden that receives at least 6 hours of direct sunlight and has loose, fertile soil.
- Prepare the soil: Before planting your Walla Walla onion seeds, prepare the soil by removing any weeds or debris and adding organic matter such as compost or well-rotted manure. This will improve the soil structure and fertility, which will help your onions grow strong and healthy.
- Start seeds indoors: Walla Walla onion seeds can be started indoors about 8-10 weeks before the last frost date in your area. Sow the seeds in individual pots or seed trays, and keep them in a warm, sunny location. Keep the soil moist but not waterlogged, and fertilize with a balanced fertilizer every 2 weeks.
- Transplant seedlings: Once the seedlings have reached about 6 inches in height and have developed a strong root system, they can be transplanted into the garden. Choose a cloudy day or late afternoon to transplant, and make sure to space the seedlings about 4-6 inches apart.
- Water and fertilize: Walla Walla onions require consistent moisture and regular fertilization to grow well. Water deeply once a week, and fertilize with a balanced fertilizer every 3-4 weeks. Avoid over-fertilizing, as this can cause the onions to grow too quickly and become watery.
- Harvest and store: They are ready to harvest when the tops have begun to fall over and dry out. Carefully dig up the onions with a garden fork, and let them dry in a warm, dry location for a few days. Once they are completely dry, trim the tops and store the onions in a cool, dry location.
