This comprehensive guide will provide you with all the information you need to grow onions in Minnesota, from selecting the right variety to harvesting and storing your crop. So, let’s get started!

1. Choosing the Right Onion Variety for Minnesota

When it comes to growing onions in Minnesota, choosing the right variety is crucial. Some popular onion varieties that thrive in Minnesota’s climate include:

• Northern White Onion: This variety is known for its mild flavor and long storage life. It is a good choice for both fresh use and storage.

• Red Onion: Red onions are known for their vibrant color and sharp flavor. They are often used in salads, stir-fries, and as a garnish.

• Sweet Onion: Sweet onions have a mild, sweet flavor and are perfect for eating raw or cooked. They are a popular choice for salads, sandwiches, and grilling.

2. Preparing the Soil for Onion Cultivation

Onions prefer well-drained, sandy loam soil with a pH between 6.0 and 6.8. If your soil is not ideal, you can amend it with compost, manure, or other organic matter to improve its structure and fertility.

3. Planting Onion Sets or Seeds

Onion sets are small, immature onions that are planted in the spring. Seeds can also be sown directly into the soil, but this method takes longer to produce mature onions.

• Planting Onion Sets: Plant onion sets about 1 inch deep and 4 inches apart in rows that are 12 to 18 inches apart.

• Sowing Onion Seeds: Sow onion seeds about 1/4 inch deep and 1 inch apart in rows that are 12 to 18 inches apart.

4. Watering and Fertilizing Onion Plants

Onions need regular watering, especially during dry spells. Aim to provide about 1 inch of water per week. Fertilize onion plants with a balanced fertilizer, such as a 10-10-10 NPK fertilizer, every few weeks.

5. Pest and Disease Control

Onions can be susceptible to pests and diseases, such as onion maggots, thrips, and downy mildew. To prevent these problems, practice good garden hygiene, such as removing weeds and crop debris, and use organic pest control methods whenever possible.

6. Harvesting and Storing Onions

Onions are ready to harvest when the tops start to turn brown and fall over. Gently lift the onions from the soil and allow them to dry in the sun for a few days. Once the onions are dry, cut off the tops and store them in a cool, dry place.
