Description

Walla Walla Onion is a long-day onion variety that works great in northern climates. This is a sweet onion that gets large and will average 2-3 pounds. It has a mild, sweet flavor that compares to the Vidalia onions grown in the southern states. Walla Walla matures relatively early and can also be grown in some intermediate-day growing zones.

Long-day Onions

Plant in spring for a mid-summer harvest

Start the bulbing process when day length reaches 14-16 hours

 

Growing Information

Onions are heavy feeders and will require significant nutrient inputs throughout their lifespan. We recommend feeding them with our 20-20-20 and Calcium Nitrate fertilizers. Fertilize with 20-20-20 shortly after transplanting. The phosphorous and potassium in the 20-20-20 fertilizer will help to promote solid root development, while the nitrogen will promote vegetative growth. Once transplants are established, we recommend side-dressing or injecting with our Calcium Nitrate fertilizer. Side dress or inject 1 cup per 20 feet of linear row every 3-4 weeks after transplanting.
