What You Need to Grow Leeks in Water

1. Leek Bases
   • Use the white root ends of leeks, about 5–7cm long.
2. Container
   • A glass jar, cup, or bowl that allows the base to sit upright.
3. Water
   • Fresh, clean water is essential for healthy regrowth.
4. Sunny Spot
   • Place the container on a windowsill with plenty of natural light.

Step-by-Step Guide to Growing Leeks in Water

1. Prepare the Leek Bases

• Cut the green tops off the leeks, leaving the white root end intact.
• Rinse the bases thoroughly to remove any dirt or debris.

2. Choose the Right Container

• Select a jar or cup that allows the leek base to stand upright without tipping over.
• Add enough water to cover the roots but not the entire base, as this can cause rotting.

3. Position the Container

• Place the jar on a sunny windowsill where the leeks will receive plenty of light.
• Rotate the container occasionally to ensure even exposure to sunlight.

4. Maintain the Water

• Change the water every 2–3 days to prevent bacterial growth and keep it fresh.
• Ensure the roots remain submerged but avoid overfilling the container.

Caring for Leeks Growing in Water

1. Light
   • Place the container in a bright location with 6–8 hours of sunlight daily. Use grow lights if natural light is insufficient.
2. Water Quality
   • Always use clean, fresh water and change it regularly to avoid foul odors and rotting.
3. Trimming Leaves
   • As the green tops grow, trim them regularly to encourage continued growth.
4. Temperature
   • Maintain an indoor temperature between 15–22°C for optimal growth.

Harvesting Leeks Grown in Water

1. When to Harvest
   • Green shoots will start growing within a few days and can be harvested once they reach 10–15cm tall.
2. How to Harvest
   • Trim the green tops with scissors, leaving the white base intact for further regrowth.
3. Repeat the Process
   • Leeks can regrow multiple times from the same base, though growth may slow after a few cycles.

Common Problems and Solutions

1. Rotting Base
   • Cause: Submerging the entire leek base in water or not changing the water frequently enough.
   • Solution: Ensure only the roots are submerged and change the water every 2–3 days.
2. Slow Growth
   • Cause: Insufficient sunlight or poor water quality.
   • Solution: Move the container to a sunnier spot and ensure fresh water is used.
3. Foul Odor
   • Cause: Bacterial growth in stagnant water.
   • Solution: Clean the container thoroughly and replace the water more frequently.
4. Yellowing Leaves
   • Cause: Lack of nutrients or overexposure to heat.
   • Solution: Trim yellow leaves and move the container to a cooler location.
