Selecting the Right Onion Bulbs
The first step in growing onions from bulbs is selecting the right varieties. Choose disease-resistant, high-yielding onion bulbs that are suitable for your climate and growing season. Some popular varieties include:
- Yellow onions: Granex, Copra, and Walla Walla
- White onions: White Sweet Spanish, Crystal White Wax, and Snow White
- Red onions: Red Baron, Red Wing, and Burgundy
Preparing the Soil
Onions prefer well-drained, fertile soil with a pH of 6.0 to 6.8. Amend your soil with plenty of organic matter, such as compost or manure, to improve its structure and fertility. Avoid planting onions in soil that has been recently fertilized with fresh manure, as this can promote disease.
Planting the Bulbs
Plant onion bulbs in the spring or fall, when the soil temperature is between 50 and 60 degrees Fahrenheit. Dig a hole that is twice the diameter of the bulb and plant it root-side down. Cover the bulb with soil, leaving the top 1/3 of the bulb exposed. Space the bulbs 4 to 6 inches apart.
Watering and Fertilizing
Water onions regularly, especially during dry spells. Avoid overwatering, as this can lead to rot. Fertilize onions every few weeks with a balanced fertilizer.
Controlling Pests and Diseases
Onions are susceptible to a variety of pests and diseases, including thrips, onion flies, and downy mildew. Monitor your plants regularly for signs of pests or diseases and treat them promptly with appropriate measures.
Harvesting Onions
Onions are ready to harvest when the tops of the plants 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. Store onions in a cool, dry place for several months.
Growing Onions in Containers
Growing onions in containers is a great option for gardeners with limited space or poor soil conditions. Choose a container that is at least 12 inches deep and has drainage holes. Fill the container with a well-draining potting mix and plant the onion bulbs as described above.
Tips for Success
- Plant onion bulbs in full sun.
- Rotate your onion crops to prevent disease build-up.
- Mulch around your onions to suppress weeds and retain moisture.
- Avoid planting onions near beans, peas, or garlic.
- Harvest onions when they are mature to prevent storage diseases.
