If you love cooking with fresh green onions, you know how quickly a single bunch can disappear — and how expensive constant restocking can get.
One creative gardener has found a way to keep the flavorful herb coming all season long without repeated trips to the grocery store. Her clever hack turns kitchen scraps into an endless supply of green onions, saving money and reducing food waste at the same time.
The scoop
Mrs. Vee (@ourlittlegreenoasis) shared her trick on TikTok, showing how she plants the root ends of store-bought green onions alongside her potatoes. Even though she jokes that her potato patch is a little overcrowded, she explains that the onion roots won’t compete for space and will quickly sprout new shoots.
@ourlittlegreenoasis yes i know these potatoes are overcrowded but it just is what it is, I didnt think they were all gonna take take! but these roots will grow into green onions and won’t compete with much from the potatoes underground so it will be fine 🙂 #gardening #fyp #gardentok #kitchenhacks #tiktoklearningcampaign ♬ original sound – Mrs.Vee💚 @OurLittleGreenOasis
She added that green onions make great companion plants because they naturally help repel pests and fungal diseases. With nothing more than a few leftover onion bottoms and some garden soil, you can create a self-renewing source of this kitchen staple.
How it’s helping
This easy, no-waste planting method stretches every grocery dollar by eliminating the need to buy new bunches each week. Freshly harvested green onions also pack more flavor than store-bought ones, making home-cooked meals taste even better.
Growing your own food offers more than just tastier produce — research shows that gardening can reduce stress and boost mental health, while the physical activity helps keep you moving. Plus, every homegrown harvest lowers the environmental impact of mass-produced, globally shipped vegetables.
