The green onion is a versatile ingredient suitable for Mexican, Asian, Indian, and Western cuisine alike, offering a crisp texture and a clean, mild flavor to whatever dish it serves.
They are not an overly expensive buy, but the price of a bundle of green onions is rising, according to Fresh Plaza. Jochen Fehmel from the Palatinate region of Germany informed Fresh Plaza that unusually cool temperatures have impacted crop quality and yield.

To achieve this feat, all a consumer must do is save the white bulb and root system from an already-consumed green onion. Place the bulb in water and wait; what will result is a batch of fresh and free green onions.
This hack can be duplicated time and time again, meaning once a consumer begins to grow their own green onions, they essentially never have to purchase the produce item again.
How it’s helping
According to Martha Stewart, green onions grow in semi-cool temperatures, between 55 to 75 degrees Fahrenheit. If they are planted in extreme heat or cold, the crops will die.
During the 2024 growing season for green onions in Germany, frosts below negative-5 degrees Celsius, or 23 degrees Fahrenheit, damaged green onion crops, according to Fresh Plaza. This will presumably damage the 2025 yield.

In the face of climate change, places across Europe experience intense winters with the collapse of the polar vortex, according to DW. Dirty energy use not only heats the planet but also causes extreme weather events.
Grocery prices, in response, rise, so many consumers are opting to grow food at home. Homegrown produce saves consumers money, tastes better, and minimizes consumer waste. An investment of $70 put toward gardening can save a consumer $600 on produce annually.
Additionally, gardening at home or at the community level improves consumers’ mental health.
What everyone’s saying
Commenters on TikTok confirmed the ease of homegrown green onions.
One has used this hack before: “My nephew taught me this years ago and I was amazed at how easy!”
Another shared that this growing method does not limit itself to green onions. They said, “You can do the same with celery.”
