The amazing green onion plant will easily regrow itself in a glass of water. You do not need to continue to buy them at the store because you can just grow them yourself. It is a very easy process to cut off the tops and use them and then put the remainder in a glass with water. It will be fun to watch them grow and just another way to be independent.
Key Takeaways:
- Certain vegetables can be regrown and only need to be purchased once
- Green onions can be regrown if the bulb is intact
- Place the bulbs in a jar or glass filled with water and place in sunlight
“”Either way, you’ll have a virtually inexhaustible supply of green onions for the cost of a single trip to the produce section of your grocery store.””
