How to Grow Spring Onions

From Seeds

  1. Prepare the Soil:
    • Choose well-draining soil enriched with compost.
    • Spring onions prefer slightly acidic to neutral pH (6.0-7.0).
  2. Plant the Seeds:
    • Sow seeds ½ inch deep in rows spaced 4-6 inches apart.
    • Cover lightly with soil and water gently.
  3. Thin the Seedlings:
    • When seedlings are 2-3 inches tall, thin to 1-2 inches apart for proper growth.

From Sets

  1. Prepare the Soil:
    • Loosen the soil and remove weeds.
  2. Plant the Sets:
    • Push onion sets (small bulbs) into the soil with the pointed end facing up, about 1 inch deep and 3 inches apart.
  3. Water Regularly:
    • Keep the soil moist but not waterlogged.

From Kitchen Scraps

  1. Cut the Roots:
    • Save the root ends of store-bought spring onions, leaving about 1 inch of the white base.
  2. Place in Water:
    • Submerge the roots in a glass of water, ensuring the top stays dry.
  3. Transplant to Soil:
    • Once roots are established, plant them in soil and water regularly.

Best Conditions for Growing Spring Onions

  1. Light:
    • Spring onions thrive in full sun but can tolerate partial shade.
  2. Temperature:
    • Ideal range: 60°F-75°F (15°C-24°C). They can handle cooler weather but may bolt in extreme heat.
  3. Water:
    • Keep soil evenly moist but not soggy.
  4. Soil:
    • Well-draining, fertile soil with plenty of organic matter.

Caring for Your Spring Onions

  1. Weeding:
    • Remove weeds regularly to prevent competition for nutrients.
  2. Fertilizing:
    • Apply a balanced fertilizer every 2-3 weeks for robust growth.
  3. Pest Control:
    • Watch for pests like onion flies and aphids. Use natural remedies like neem oil if needed.
  4. Mulching:
    • Add a layer of mulch to retain moisture and reduce weeds.

How to Harvest Spring Onions

  • Timing:
    • Harvest spring onions when they’re about 6-8 inches tall, typically 6-8 weeks after planting.
  • How to Harvest:
    • Gently pull them from the soil or use scissors to cut the green tops.
  • Tip:
    • Leave a small portion of the bulb in the soil to encourage regrowth.

Common Problems and Solutions

  1. Yellowing Leaves:
    • Cause: Overwatering or nutrient deficiency.
    • Solution: Adjust watering schedule and fertilize with nitrogen-rich compost.
  2. Bolting (Premature Flowering):
    • Cause: High temperatures or stress.
    • Solution: Harvest early or choose heat-resistant varieties.
  3. Pests:
    • Onion Flies: Use floating row covers to prevent infestations.
    • Aphids: Spray with soapy water or neem oil.

Regrowing Spring Onions

Spring onions are one of the easiest vegetables to regrow:

  1. Cut and Save:
    • Leave about 1 inch of the white bulb intact after harvesting.
  2. Place in Water:
    • Submerge the roots in a small glass of water and place in a sunny spot.
  3. Transplant:
    • After a week, when new shoots appear, plant them in soil for continued growth.
