Choosing the Right Bulbs
The foundation of successful onion cultivation lies in selecting healthy and viable bulbs. Look for bulbs that are firm, free of blemishes, and have a dry, papery outer skin. Avoid bulbs that are soft, moldy, or have sprouted.
Preparing the Soil
Multiplier onions thrive in well-drained, fertile soil with a pH between 6.0 and 6.8. Before planting, amend the soil with plenty of organic matter, such as compost or manure, to improve its structure and fertility. The ideal soil depth for planting is 12-18 inches.
Planting Time and Depth
The optimal time to plant multiplier onion bulbs is in the spring, after the last frost date. Plant the bulbs pointy side up, spacing them 4-6 inches apart in rows that are 12-18 inches apart. The depth of planting should be about 1-2 inches below the soil surface, with the tip of the bulb just visible.
Watering and Fertilizing
Water the onions regularly, especially during dry periods. Avoid overwatering, as this can lead to rot. Fertilize the onions monthly with a balanced fertilizer to promote healthy growth and bulb development.
Mulching and Weed Control
Mulching around the onions with straw or shredded leaves helps retain moisture, suppress weeds, and regulate soil temperature. Regularly remove any weeds that may compete with the onions for nutrients and water.
Harvesting and Storage
Multiplier onions are typically ready to harvest in late summer or early fall, when the tops start to turn brown and fall over. Gently lift the bulbs from the soil and allow them to dry in a well-ventilated area for a few weeks before storing. Store the onions in a cool, dry place with good air circulation.
Troubleshooting Common Problems
- Onion Fly: These pests can damage onion bulbs. Use row covers or neem oil to deter them.
- Thrips: These insects can cause silvery streaks on onion leaves. Use insecticidal soap to control them.
- Botrytis Blight: This fungal disease can cause onions to rot. Improve air circulation and avoid overwatering to prevent it.
