5. Planting Spring Onions

Once your soil is prepared, it’s time to plant your spring onions. Here’s a step-by-step guide:

Step-by-Step Planting Guide

1. Seeds or Sets: Decide whether to plant seeds or onion sets. Seeds offer a wider variety, while sets provide quicker results.
2. Sowing: Plant seeds 1/4 inch deep and 1 inch apart for optimal spacing.
3. Watering: Water the area gently to avoid washing away the seeds.

6. Care and Maintenance

To ensure healthy growth, regular care and maintenance are essential. Here are key practices to follow:

Watering

Spring onions require consistent moisture. Water them regularly, especially during dry spells, ensuring they do not become waterlogged.

Fertilizing

Apply a balanced fertilizer every few weeks to promote robust growth. Organic options such as fish emulsion or compost tea are excellent choices.

Weed Control

Keep the planting area free from weeds, which can compete for nutrients and water. Mulching can help suppress weed growth.

7. Pest and Disease Management

While spring onions are generally hardy, they can be susceptible to certain pests and diseases. Here’s how to manage them:

Common Pests

• Onion Maggot: Use row covers to protect seedlings.
• Thrips: Implement insecticidal soap or neem oil as a treatment.

Diseases

Watch for signs of diseases such as downy mildew. Ensure good air circulation and avoid overhead watering to minimize fungal issues.

8. Harvesting and Storage

Knowing when and how to harvest your spring onions is essential for the best flavor:

Harvesting

Spring onions are typically ready to harvest when they reach 6-8 inches tall. Gently pull them from the soil, being cautious not to damage neighboring plants.
