This popular variety is known for its large size, juicy texture, and delicate flavor. In this article, we’ll cover everything you need to know about planting Walla Walla onions, from choosing the right location to harvesting your crop.

Choosing the Right Location

Before you start planting your Walla Walla onions, you need to choose the right location. These onions prefer full sun and well-draining soil. They also need plenty of space to grow, so make sure you plant them in an area with enough room for their large bulbs.

Preparing the Soil

To prepare the soil for planting, start by removing any weeds or debris from the area. Then, dig a hole about six inches deep and add some compost or other organic matter to the soil. Mix it in well and then level the area.

Planting the Onions

To plant your Walla Walla onions, start by making a small hole in the soil using your finger or a dibber. Then, place the onion bulb in the hole with the root end facing down. Cover the bulb with soil, leaving the tip of the onion exposed. Space the onions about six inches apart to allow for proper growth.

Caring for Your Onions

Once your Walla Walla onions are planted, it’s important to care for them properly to ensure a healthy crop. Here are some tips for taking care of your onions:

Watering

Onions need regular watering, especially during dry spells. Water them deeply once a week, making sure the soil is moist but not waterlogged. Avoid overhead watering, as this can lead to fungal diseases.

Fertilizing

Onions benefit from regular fertilization to promote healthy growth. Use a balanced fertilizer every two weeks, or apply a slow-release fertilizer at planting time.

Weeding

Keep the area around your onions free of weeds to prevent competition for nutrients and water. Pull weeds by hand or use a hoe to remove them.

Pest Control

Onions are susceptible to a variety of pests, including onion maggots and thrips. Use insecticidal soap or neem oil to control these pests, or try using row covers to prevent them from infesting your crop.

Harvesting Your Onions

Walla Walla onions are ready to harvest when the leaves start to turn yellow and fall over. Gently lift the bulbs out of the soil and let them dry in the sun for a few days. Once they’re dry, cut off the tops and store them in a cool, dry place.

Troubleshooting Common Problems

Even with proper care, you may encounter some problems when growing Walla Walla onions. Here are some common issues and how to address them:

Bolting

Bolting occurs when the onion produces a flower stalk instead of a bulb. This is usually caused by stress, such as temperature fluctuations or lack of water. To prevent bolting, make sure your onions are planted in a location with consistent moisture and temperature.

Disease

Walla Walla onions are susceptible to a variety of diseases, including onion smut and downy mildew. To prevent disease, make sure you plant disease-resistant varieties and avoid overhead watering.

Pests

As mentioned earlier, onion maggots and thrips can be a problem for Walla Walla onions. Use insecticidal soap or neem oil to control these pests, or try using row covers to prevent them from infesting your crop.

Small Bulbs

If your Walla Walla onions are producing small bulbs, it may be due to overcrowding or lack of nutrients. Make sure you’re spacing your onions properly and fertilizing them regularly to promote healthy growth.

Planting Walla Walla onions is a great way to add a delicious and versatile vegetable to your garden. By following these tips for choosing the right location, preparing the soil, planting the onions, and caring for them properly, you can enjoy a bountiful harvest of sweet and juicy onions.
