Green onions, also known as scallions or spring onions, are a type of onion that is harvested while the vegetable is still immature. They have a milder flavor than regular onions and their green stems can be eaten raw or cooked in many recipes. These tasty veggies can be added to salads, stir-fries, omelettes and other dishes for an extra kick of flavor.
Why Regrow Green Onions?
Regrowing green onions from the scraps you would normally throw away can save money on grocery bills and provide a steady supply of fresh vegetables all year round. Plus, it’s fun and easy to do! All you need are some simple supplies and the knowledge of how to regrow green onions.
3 Easy Steps to Regrow Green Onions
- Choose the right scallions: Look for scallions with at least 2 inches of white stem remaining above the roots. The more stem, the better.
- Place them in water: Fill a cup or bowl with water and place the cut ends of your scallions into the water so they’re submerged up to the base of the white stems. Change out the water every couple of days to keep it clean.
- Move them to soil: When the scallions start to grow new roots and leaves, it’s time to move them to a pot filled with rich, nutrient-dense soil. Keep the soil moist but not soggy and put them in a spot that gets plenty of sunlight (at least six hours per day).
Using the Scallions After Regrowth
Once your scallions have been replanted into soil and given enough time to grow (typically one to two weeks), you’ll be ready to harvest and enjoy! To use them, simply trim off what you need with kitchen scissors and store any leftovers in an airtight container in the refrigerator. You can then use these freshly grown greens in all your favorite dishes.

- Fertilize regularly – Feed your plants once a month using liquid fertilizer to give them essential nutrients for strong growth.
- Prune regularly – Cut back wilted stalks and leaves as needed to promote healthy growth.
- Thin overcrowded patches – If multiple sprouts appear in one area, remove some so each plant has adequate space to thrive.
