How Do You Grow Green Onions After Cutting?

You can easily regrow green onions after cutting by placing the root end in water or directly planting it in soil. Here's how:

Regrowing Green Onions in Water

This is the simplest and most common method.

Cut Properly: When harvesting green onions, cut off the green tops, leaving about 1-2 inches of the white bulb and roots intact. This is the crucial part for regrowth.
Prepare a Container: Find a small jar, glass, or container.
Add Water: Fill the container with enough water to submerge the white bulb, but try to keep the green shoots above the water line to prevent rot.
Place in Sunlight: Position the container in a sunny windowsill or a location with bright, indirect light.
Change the Water Regularly: Replace the water every 1-2 days to keep it fresh and prevent bacterial growth.
Watch Them Grow: You should see new green shoots emerging within a few days. You can harvest these as needed.

This method allows for potentially more robust growth.

Cut Properly: As with the water method, leave about 1-2 inches of the white bulb and roots.
Prepare the Soil: Plant the green onion bulb in a small pot or directly in your garden. Use well-draining soil.
Planting Depth: Bury the white bulb, leaving the green shoots exposed.
Water Regularly: Keep the soil consistently moist, but not soggy.
Provide Sunlight: Place the pot in a sunny location.
Harvesting: You can harvest the green tops as they grow. If planting in the garden, space them a few inches apart for optimal growth.

Healthy Starting Material: The healthier the original green onion, the better it will regrow.
Fresh Water: Regular water changes are crucial for preventing rot and promoting healthy growth, especially with the water method.
Sunlight: Adequate sunlight is essential for photosynthesis and growth.
Fertilizer (Optional): For soil-grown green onions, you can occasionally add a diluted liquid fertilizer to promote faster growth, but it's generally not necessary.
Continuous Harvest: Continue cutting the green tops as needed, but always leave a portion of the green shoot to allow for further growth.

By following these simple steps, you can easily regrow green onions from scraps, providing a continuous supply of fresh herbs for your cooking!
