Why Grow Spring Onions in Water?

Growing spring onions in water offers several benefits:

• Eco-Friendly: Reduces food waste by regrowing scraps.
• Low Maintenance: Requires minimal time and effort.
• No Garden Needed: Perfect for small spaces, apartments, or windowsills.
• Continuous Harvest: Provides a steady supply of fresh greens.

What You’ll Need

To grow spring onions in water, you’ll need:

1. Spring Onion Roots:
   • Use the root ends of store-bought spring onions, leaving about 1-2 inches of the white base intact.
2. A Glass or Jar:
   • A small, clear glass or jar works best to hold the roots.
3. Water:
   • Clean, room-temperature water.
4. Sunny Spot:
   • A windowsill or another area with bright, indirect sunlight.

Step-by-Step Instructions

1. Prepare the Roots:
   • Trim the green tops of the spring onions, leaving about 1-2 inches of the white base with roots intact.
2. Set Up the Glass:
   • Fill a glass or jar with about 1-2 inches of water, enough to submerge the roots without covering the white base entirely.
3. Place the Roots in Water:
   • Position the spring onion roots in the water, ensuring the roots are fully submerged but the white base remains above water.
4. Find a Sunny Spot:
   • Place the glass on a sunny windowsill or in a well-lit area. Bright, indirect sunlight is ideal.
5. Change the Water:
   • Replace the water every 2-3 days to prevent bacteria buildup and keep the roots healthy.
6. Watch Them Grow:
   • Within a few days, you’ll notice green shoots starting to grow. Spring onions typically regrow fully in 7-10 days.

Tips for Successful Growth

1. Choose Fresh Roots:
   • Use spring onions with healthy, firm roots for the best results.
2. Don’t Overfill the Water:
   • Avoid submerging the white base entirely, as this can lead to rot.
3. Keep the Glass Clean:
   • Wash the glass when changing the water to prevent algae growth.
4. Rotate the Glass:
   • Rotate the glass occasionally to ensure even sunlight exposure.

How to Use Regrown Spring Onions

Regrown spring onions are versatile and can be used in various dishes:

• As a Garnish:
  • Chop the green tops and sprinkle over soups, salads, or stir-fries.
• In Cooking:
