What You’ll Need
Before we get started, let’s gather our supplies. This is a pretty low-maintenance project, so you probably already have most of these things lying around:
* Green Onion Scraps: The bottom 1-2 inches of your green onions, with the roots still attached. Don’t throw those away after you’ve chopped off the green parts!
* A Glass or Jar: Something to hold the green onion scraps and water. A small drinking glass, a mason jar, or even a repurposed yogurt container will work perfectly.
* Water: Tap water is just fine.
* A Sunny Spot: A windowsill or any area that gets plenty of sunlight.
* Potting Soil (Optional): If you want to transplant your green onions to a pot for longer-term growth.
* A Small Pot (Optional): If you’re choosing to transplant.
* Scissors or a Knife: For harvesting your green onions.
The Water Propagation Method: Step-by-Step
This is the easiest and most common method for regrowing green onions. It’s quick, simple, and you can literally watch them grow!
1. Prepare Your Green Onion Scraps: Take your green onion scraps and gently rinse them under cool water to remove any dirt or debris. Make sure the roots are clean. If the roots are excessively long, you can trim them slightly, but be careful not to cut them off completely. We need those roots!
2. Place Scraps in Water: Fill your glass or jar with enough water to cover the roots of the green onion scraps, but not so much that the entire white part is submerged. You only want the roots to be sitting in the water.
3. Find a Sunny Spot: Place the glass or jar on a windowsill or in another area that receives plenty of sunlight. Green onions need sunlight to grow, so this is a crucial step.
4. Change the Water Regularly: This is important to prevent bacteria growth and keep your green onions healthy. Change the water every 1-2 days. You’ll notice the water can get a little cloudy, so fresh water is key.
5. Watch Them Grow!: Within a few days, you should start to see new green shoots emerging from the top of the green onion scraps. It’s so exciting to watch!
6. Harvest Your Green Onions: Once the green shoots have grown to a reasonable length (usually a few inches), you can start harvesting them. Use scissors or a knife to cut off the green part, leaving about an inch or two of the green onion above the water line. This will allow the green onions to continue to grow.
7. Repeat and Enjoy!: Continue to change the water regularly and harvest your green onions as needed. You can keep them growing in water for quite a while, but eventually, they might start to lose their vigor. That’s when it’s time to consider transplanting them to soil.
Transplanting to Soil: For Long-Term Growth
If you want to keep your green onions growing for an extended period, transplanting them to soil is the way to go. This will provide them with more nutrients and allow them to develop a stronger root system.
1. Prepare Your Pot: Choose a small pot with drainage holes. Fill it with good-quality potting soil.
2. Carefully Remove the Green Onions from Water: Gently remove the green onion scraps from the water. Be careful not to damage the roots.
3. Plant the Green Onions: Make a small hole in the soil and plant the green onion scraps, burying the white part and the roots. Leave the green shoots exposed.
4. Water Thoroughly: Water the soil thoroughly after planting.
5. Place in a Sunny Spot: Place the pot in a sunny spot, just like when they were in water.
6. Water Regularly: Keep the soil consistently moist, but not soggy. Water when the top inch of soil feels dry to the touch.
7. Fertilize (Optional): You can fertilize your green onions every few weeks with a diluted liquid fertilizer to encourage growth.
8. Harvest and Enjoy!: Harvest your green onions as needed, just like you did when they were growing in water.
Troubleshooting Tips
Even with the simplest DIY projects, sometimes things don’t go exactly as planned. Here are a few common issues you might encounter and how to fix them:
* Green Onions Aren’t Growing: Make sure they’re getting enough sunlight. Green onions need at least 6 hours of sunlight per day. Also, ensure you’re changing the water regularly. If they still aren’t growing, try adding a drop or two of liquid fertilizer to the water.
* Green Onions Are Turning Yellow: This could be a sign of overwatering or underwatering. Make sure the soil is consistently moist, but not soggy. If they’re in water, make sure you’re changing it frequently. Yellowing can also indicate a nutrient deficiency, so consider fertilizing them.
* Roots Are Rotting: This is usually caused by bacteria growth in the water. Make sure you’re changing the water every 1-2 days. If the roots are already rotting, you can try trimming off the affected parts, but if the rot is extensive, it might be best to start with fresh scraps.
* Pests: While green onions are relatively pest-resistant, they can sometimes be affected by aphids or other small insects. If you notice any pests, you can try washing them off with a strong stream of water or using an insecticidal soap.
Extra Tips for Success
* Experiment with Different Varieties: While this method works best with green onions, you can also try it with other types of onions, such as scallions or leeks.
* Use Filtered Water: If your tap water is heavily chlorinated, you might want to use filtered water for best results.
* Rotate Your Crops: If you’re growing green onions in soil, rotate them to a different spot in your garden each year to prevent soilborne diseases.
* Successive Planting: To ensure a continuous supply of green onions, start new scraps every few weeks.
* Don’t Over-Harvest: Give your green onions time to recover between harvests.
* Enjoy the Process!: Regrowing green onions is a fun and rewarding project. Don’t be afraid to experiment and have fun with it!
Why This Works: The Science Behind the Magic
You might be wondering, “How does this even work?” Well, green onions, like many plants, have the ability to regenerate from their base. The white part of the green onion contains dormant cells that, when provided with water and sunlight, can sprout new roots and shoots. It’s a form of vegetative propagation, which is a natural way for plants to reproduce asexually. By providing the right conditions, we’re essentially giving the green onion scraps a second chance at life!
Beyond Green Onions: Other Veggies You Can Regrow
Once you’ve mastered the art of regrowing green onions, you might be inspired to try regrowing other vegetables from scraps. Here are a few other easy options:
* Lettuce: Place the lettuce stump in a bowl of water and watch it sprout new leaves.
* Celery: Similar to lettuce, place the celery base in water and transplant it to soil once roots develop.
* Garlic: Plant a single garlic clove in soil and it will grow into a new garlic bulb.
* Ginger: Plant a piece of ginger root in soil and it will sprout new shoots.
* Basil: Place basil cuttings in water and they will develop roots.
So there you have it! A comprehensive guide to regrowing green onions from scraps. It’s a simple, sustainable, and incredibly rewarding way to have fresh green onions at your fingertips. Happy gardening!

Frequently Asked Questions (FAQ)
How long does it take for green onions to regrow?
Typically, you’ll start to see noticeable regrowth within just a few days. Within a week or two, you should have enough new green onion growth to harvest. The speed of regrowth depends on factors like temperature, sunlight, and the initial health of the green onion scraps. Warmer temperatures and ample sunlight will generally promote faster growth.
What part of the green onion do I need to regrow it?
You need the bottom portion of the green onion, including the roots. Cut off the green tops, leaving about 1-2 inches of the white base with the roots attached. Make sure the roots are still intact, as they are essential for regrowth. If the roots are damaged or missing, the green onion may not regrow successfully.
Can I regrow green onions in soil instead of water?
Yes, you can! While water propagation is a great starting point, transplanting your regrown green onions to soil will allow them to grow larger and more robust. Once the roots have developed in water (usually after a week or two), you can carefully plant them in a pot filled with well-draining soil. Ensure the soil is kept moist but not waterlogged.
How often should I change the water when regrowing green onions in water?
It’s recommended to change the water every 1-2 days to prevent bacterial growth and keep the water fresh. This will help ensure the green onions have a healthy environment to regrow in. If the water becomes cloudy or discolored, change it immediately.
How much sunlight do regrowing green onions need?
Green onions thrive in bright, indirect sunlight. Place them near a sunny window where they can receive at least 6 hours of sunlight per day. If you don’t have a sunny window, you can supplement with a grow light. Insufficient sunlight can lead to leggy growth and a less vibrant color.
Can I regrow green onions indefinitely?
While you can continue to harvest from the same green onion base for several weeks, eventually, the regrowth will slow down and the flavor may become less intense. It’s best to start new green onion scraps every few weeks to ensure a continuous supply of fresh, flavorful green onions.
What if my green onions start to turn yellow or brown?
Yellowing or browning can indicate a few issues. It could be due to overwatering, underwatering, lack of sunlight, or nutrient deficiency. Ensure the water is changed regularly, the green onions are receiving adequate sunlight, and the soil (if planted in soil) is well-draining. If the problem persists, consider adding a diluted liquid fertilizer to the water or soil.
Can I use tap water to regrow green onions?
Yes, you can use tap water, but it’s best to let it sit for 24 hours before using it to allow the chlorine to dissipate. Alternatively, you can use filtered water or rainwater. Chlorine can sometimes inhibit growth, so using dechlorinated water is preferable.
Are there any pests or diseases that affect regrowing green onions?
Green onions are generally resistant to pests and diseases, but they can occasionally be affected by aphids or fungal infections. If you notice aphids, you can wash them off with a strong stream of water or use insecticidal soap. To prevent fungal infections, ensure good air circulation and avoid overwatering.
Can I freeze regrown green onions for later use?
Yes, you can freeze regrown green onions. Simply chop them into small pieces and place them in a freezer-safe bag or container. They can be added directly to your cooking without thawing. Freezing is a great way to preserve your harvest and prevent waste.
Will the regrown green onions taste the same as store-bought ones?
Yes, the regrown green onions will generally taste the same as store-bought ones. However, the flavor may become slightly milder over time as the plant continues to regrow. Starting with fresh, high-quality green onions will ensure the best flavor in your regrown harvest.
Is regrowing green onions organic?
If you start with organic green onions and use organic practices (like using organic soil and avoiding pesticides), then your regrown green onions can be considered organic.
