How to Grow Walla Walla Onions?
To grow Walla Walla onions first check your soil and make sure it drains well. Also check the pH of the soil. It should be between 6. 2 and 6. 8. You can grow Walla Walla onions either from seed or bulb. In either case, plant them in September in pots with potting soil and transplant around 60 days later to the ground. Once the seed has germinated, fertilize. Apply water as needed.
