Ever wish there was a cheap and easy way to toughen up your plants? The answer may be sitting in your kitchen. 

The scoop

Onions are not only good for you and your dinner, but they also help keep other plants strong and healthy. 

According to a study by the Shreeyash Institute of Pharmaceutical Education and Research, the compounds found inside the average onion can promote plant growth, build resistance to fungus and disease, and ward off pests.

As TikToker Claudia Orange (@claudiaorange33) demonstrated in a short video, making this happen is easy.

@claudiaorange33 Dont throw away your onion scraps, save the onion water for your plants & thank me later🪴🪴 #plantmomma #señoraera #onionwater #consejosdemipadre #plantlife #fatherknowsbest #crazyplantlady #sundayreset ♬ In The Forest (Acoustic Indie No Copyright) – Instrumental – Lesfm & Olexy

All you have to do is save your onion scraps after chopping — peels and all — and toss them in some water. Let them soak for a day or two, and that water will turn into a natural fertilizer packed with nutrients your plants will love. Feed your plants this oniony drink whenever you would normally water them.

For starters, store-bought soil and fertilizers are not cheap, but there are plenty of onion scraps to go around that might otherwise get thrown out. Got more food scraps? There are many other ways to get the most out of them and reduce food waste. 

Plus, many fertilizers and pesticides are made with harmful chemicals that do more harm than good in the long run. With onion scraps, you don’t have to worry about something toxic ending up in your yard or on your skin. 

“I’ve saved so much money buying fertilizer, and my plants have never looked this beautiful,” Claudia said.
