Yes, you can easily grow more green onions in water from the scraps of previously used green onions. This is a simple and effective way to regrow them without soil.
How to Regrow Green Onions in Water
Regrowing green onions in water is a popular and simple gardening hack. Here’s how to do it:
- Save the Scraps: After using green onions, save the white bulb ends, about 1-2 inches from the root end.
- Place in Water: Put the white ends, root-side down, in a glass or jar with enough water to cover the roots.
- Sunlight: Place the glass in a sunny location, such as a windowsill.
- Change Water Regularly: Change the water every 1-2 days to prevent bacterial growth and keep the onions healthy.
- Watch Them Grow: You should see new green shoots emerging within a few days.
- Harvest: You can snip off the green shoots as needed for cooking. The green onions will continue to regrow.
Benefits of Regrowing Green Onions in Water
- No Soil Needed: This method is ideal for those who don't want to deal with soil or have limited space.
- Easy and Convenient: It requires minimal effort and can be done indoors.
- Reduces Waste: It's a great way to reduce food waste by utilizing scraps.
- Continuous Supply: You can harvest fresh green onions as needed.
While the green onions will regrow in water, eventually they will deplete their nutrient reserves. For long-term growth and more robust plants, transplanting them into soil is recommended after a few weeks of regrowing in water.
