Regrow, harvest, and thrive—everything you need to know about growing green onions indoors or out, even in small spaces.
Why Green Onions Deserve a Spot in Every Home Garden
Green onions (also called scallions or spring onions) are a go-to staple for any gardener looking for fast results and zero-waste utility. They’re easy to grow, quick to regrow from scraps, and thrive in containers, making them a favorite for urban gardeners and culinary herb enthusiasts.
Method 1: Water Regrowth – The Ultimate Lazy Gardener Hack
Want near-instant gratification? Try this zero-soil method!
Steps:
- Use the white base of store-bought green onions (with roots attached).
- Place in a glass with 1–2 inches of clean water.
- Keep in a sunny windowsill. Change water every 2–3 days.
- Harvest within 7–10 days!
Pro Tip: For stronger regrowth, supplement with diluted liquid fertilizer once a week.
Method 2: Container Gardening – More Harvests, Better Flavor
Soil-grown green onions develop richer flavor and last longer per planting cycle.
Essentials:
- Container depth: Minimum 6 inches
- Soil: Loamy, loose, and well-drained
- Sunlight: At least 6 hours per day (use grow lights in winter)
- Water: When topsoil is dry to the touch
