Why Regrow Green Onions?

What You'll Need:

- Store-bought green onions

Step-by-Step Guide to Regrowing Green Onions

1. Prepare Your Green Onions

After using your store-bought green onions, save the white bulb ends with roots attached. Cut them approximately 2 inches from the root base, ensuring the roots remain intact.

2. Set Up Your Growing Station

Fill a clear glass or jar with about an inch of fresh water. Place the root ends in the water, keeping the cut portions above the waterline to prevent rotting.

3. Find the Perfect Spot

Position your growing station on a sunny windowsill. Green onions thrive in bright, indirect light. Avoid placing them in extremely hot or cold spots.

4. Maintenance

Change the water every 2-3 days to prevent bacterial growth. This simple step is crucial for successful regrowth.

5. Harvesting

Within 3-4 days, you'll notice new growth emerging. Wait until the green shoots reach 6-8 inches before harvesting. Cut what you need, leaving about 2 inches above the roots to continue the growing cycle.

Pro Tips:

- Keep water level consistent but don't submerge the growing shoots

- Harvest from the outside leaves first

- Transfer to soil after 2-3 water regrowths for longer-lasting plants

- Start multiple batches for continuous harvest

Troubleshooting Common Issues:

• Yellow tips: Usually indicates old water - change more frequently

• Slow growth: Check light exposure and water quality

• Wilting: Ensure water level is adequate
