Regrowing Green Onions From Scraps: A DIY Guide
Hey there, fellow green thumb enthusiasts! Are you tired of constantly buying green onions only to use a tiny bit and then watch the rest wilt away in your fridge? Well, I’ve got a fantastic solution for you: regrowing them from scraps! It’s super easy, incredibly rewarding, and a great way to reduce food waste. Plus, you’ll always have fresh green onions on hand for your culinary creations. Let’s dive in!
What You’ll Need
Before we get started, let’s gather our supplies. This is a pretty low-key project, so you probably already have most of this stuff lying around.
* Green Onions: Obviously! You’ll need the leftover ends of your green onions, about 1-2 inches from the root end. Make sure they still have the roots attached.
* A Glass or Jar: Any small glass or jar will do. I like to use old mason jars or even recycled glass yogurt containers.
* Water: Tap water is perfectly fine.
* Scissors or a Knife: For trimming the green onions.
* Potting Soil (Optional): If you want to eventually transplant your green onions to a pot or garden.
* A Small Pot (Optional): For transplanting.
The Water Propagation Method: Step-by-Step
This is the easiest and most common method for regrowing green onions. It’s perfect for beginners and requires minimal effort.
1. Prepare the Green Onion Scraps: Using your scissors or knife, trim the green onion stalks, leaving about 1-2 inches of the white part with the roots intact. Don’t worry if some of the roots look a little sad; they’ll bounce back. I usually cut off any yellowing or slimy parts too.
2. Place the Scraps in Water: Fill your glass or jar with enough water to cover the roots, but not so much that the entire white part of the green onion is submerged. You only want the roots to be in the water to prevent rotting.
3. Find a Sunny Spot: Place the glass or jar in a sunny windowsill or another location that receives plenty of indirect sunlight. Green onions need sunlight to grow, so this is crucial.
4. Change the Water Regularly: This is important! Change the water every 1-2 days to prevent bacteria growth and keep the water fresh. I usually just dump out the old water and refill the jar with fresh tap water.
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 them grow!
6. Harvest Your Green Onions: Once the green shoots are a few inches long, you can start harvesting them. Simply snip off the amount you need with scissors. The green onions will continue to grow back, providing you with a continuous supply.
Transplanting to Soil (Optional)
While you can continue to grow your green onions in water indefinitely, transplanting them to soil can result in thicker, more robust growth. Here’s how to do it:
1. Choose a Pot: Select a small pot with drainage holes. The size of the pot will depend on how many green onion scraps you want to plant. A 4-6 inch pot is usually sufficient for a few scraps.
2. Fill the Pot with Potting Soil: Use a good quality potting soil that drains well. Avoid using garden soil, as it can be too heavy and compact.
3. Make Small Holes: Use your finger or a pencil to create small holes in the soil, about 1-2 inches deep.
4. Plant the Green Onion Scraps: Gently place the green onion scraps into the holes, making sure the roots are covered with soil. Leave the green shoots exposed.
5. Water Thoroughly: Water the soil thoroughly after planting, until water drains out of the drainage holes.
6. Place in a Sunny Location: Just like with the water propagation method, place the pot in a sunny location that receives plenty of indirect sunlight.
7. Water Regularly: Keep the soil consistently moist, but not soggy. Water when the top inch of soil feels dry to the touch.
8. Fertilize (Optional): You can fertilize your green onions every few weeks with a diluted liquid fertilizer to promote growth.
9. Harvest Your Green Onions: Once the green shoots are a few inches long, you can start harvesting them. Simply snip off the amount you need with scissors. The green onions will continue to grow back, providing you with a continuous supply.
Troubleshooting and Tips
Even though regrowing green onions is pretty straightforward, you might encounter a few hiccups along the way. Here are some common issues and how to address them:
* Yellowing Leaves: Yellowing leaves can be a sign of overwatering, underwatering, or lack of sunlight. Make sure you’re watering properly and that your green onions are getting enough sunlight. You can also trim off any yellowing leaves to encourage new growth.
* Slimy Roots: Slimy roots are usually a sign of bacteria growth. This is why it’s so important to change the water regularly. If you notice slimy roots, rinse them off with clean water and change the water in the jar immediately.
* Slow Growth: Slow growth can be caused by a number of factors, including lack of sunlight, poor water quality, or nutrient deficiencies. Make sure your green onions are getting enough sunlight, change the water regularly, and consider fertilizing them if you’re growing them in soil.
* Rotting: If the white part of the green onion starts to rot, it’s usually because it’s been submerged in water for too long. Make sure only the roots are in the water.
Here are a few extra tips to help you succeed:
* Use Filtered Water: While tap water is generally fine, using filtered water can help prevent mineral buildup and promote healthier growth.
* Rotate the Green Onions: If you’re growing your green onions in a windowsill, rotate the jar or pot regularly to ensure that all sides of the plant receive equal sunlight.
* Don’t Overharvest: Avoid harvesting too much of the green onion at once, as this can weaken the plant.
* Experiment with Different Varieties: There are many different varieties of green onions, so experiment with different ones to see which ones grow best for you.
* Enjoy the Process!: Regrowing green onions is a fun and rewarding experience. Don’t be afraid to experiment and learn along the way.
Why This Works: The Science Behind It
You might be wondering, “How does this even work?” Well, green onions, like many other plants, have the ability to regenerate from their base. The white part of the green onion contains dormant cells that can be activated when placed in water or soil. These cells then start to divide and differentiate, forming new roots and shoots. It’s a pretty amazing process, and it’s a testament to the resilience of nature.
The roots absorb water and nutrients, while the sunlight provides the energy needed for photosynthesis, the process by which plants convert light energy into chemical energy. This energy is then used to fuel the growth of new leaves and roots. By providing the green onion scraps with water, sunlight, and a little bit of care, you’re essentially giving them everything they need to thrive.
Beyond Green Onions: Other Vegetables 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 vegetables that you can easily regrow:
* Lettuce: Place the lettuce stump in a bowl of water and watch it regrow.
* Celery: Similar to lettuce, place the celery base in water.
* Garlic: Plant a single garlic clove in soil and it will sprout.
* Ginger: Plant a piece of ginger root in soil.
* Basil: Place basil cuttings in water until roots develop, then plant in soil.
Regrowing vegetables from scraps is a great way to save money, reduce food waste, and connect with nature. It’s also a fun and educational activity for kids. So, give it a try and see what you can grow!
I hope this guide has inspired you to start regrowing your own green onions. It’s a simple, sustainable, and rewarding project that anyone can do. Happy gardening!

Frequently Asked Questions (FAQ)
How long does it take for green onions to regrow?
Generally, you’ll start to see noticeable regrowth within a few days of placing the green onion scraps in water. Within a week, you should have a significant amount of new green growth. The speed of regrowth depends on factors like temperature, sunlight, and the initial health of the green onion scraps. In optimal conditions, you can harvest new green onions every week or two.
What part of the green onion do I need to regrow it?
You only need the white bulb end with the roots attached. Cut off the green tops, leaving about 1-2 inches of the white part intact. Make sure the roots are still attached to the bulb. These roots are essential for absorbing water and nutrients, which will fuel the regrowth process.
Can I regrow green onions in soil instead of water?
Yes, absolutely! While water propagation is a great way to start, you can definitely transplant your regrowing green onions to soil. Once the roots have grown a few inches in water, carefully plant the bulb in a pot filled with well-draining potting mix. Bury the bulb up to the point where the green shoots emerge. Water regularly, keeping the soil moist but not soggy. Growing in soil can lead to more robust and flavorful green onions.
How much sunlight do regrowing green onions need?
Green onions thrive in bright, indirect sunlight. A windowsill that receives morning sun is ideal. Avoid placing them in direct sunlight, especially during the hottest part of the day, as this can scorch the leaves. If you don’t have a sunny windowsill, you can supplement with a grow light.
How often should I change the water?
It’s important to change the water every 1-2 days to prevent bacterial growth and keep the water fresh. Stagnant water can lead to rot and hinder regrowth. When you change the water, gently rinse the roots to remove any debris.
Can I use tap water to regrow green onions?
Yes, you can use tap water, but it’s best to let it sit out for a few hours to allow the chlorine to dissipate. Alternatively, you can use filtered water or rainwater.
How long can I keep regrowing the same green onion bulb?
With proper care, you can regrow the same green onion bulb multiple times. However, the regrowth may become less vigorous over time. After several harvests, the bulb may start to deteriorate. At this point, it’s best to start with fresh green onion scraps.
What if my green onions start to turn yellow or brown?
Yellowing or browning leaves can indicate a few things. It could be due to overwatering, underwatering, lack of sunlight, or nutrient deficiency. Adjust your watering schedule, ensure adequate sunlight, and consider adding a diluted liquid fertilizer. If the problem persists, the bulb may be rotting, and it’s best to start with a new one.
Can I regrow other types of onions besides green onions?
While this method works best with green onions, you can also try regrowing scallions and leeks using the same technique. The success rate may vary depending on the type of onion and its initial condition.
Are there any pests or diseases that affect regrowing green onions?
Regrowing green onions are generally pest-resistant, but they can occasionally be affected by aphids or thrips. If you notice any pests, rinse the plants with a strong stream of water or use an insecticidal soap. Overwatering can also lead to fungal diseases, so be sure to provide good drainage and avoid overcrowding.
Can I eat the regrown green onions?
Yes, absolutely! The regrown green onions are perfectly safe to eat and will have a similar flavor to store-bought green onions. Simply snip off the green tops as needed and use them in your favorite recipes.
What’s the best way to harvest the regrown green onions?
The best way to harvest is to simply snip off the green tops with scissors, leaving about an inch or two of growth. This will allow the green onions to continue regrowing. Avoid pulling the entire bulb out of the water or soil, as this will stop the regrowth process.
How can I make my regrown green onions taste better?
The flavor of regrown green onions can be enhanced by providing them with optimal growing conditions. Ensure they receive adequate sunlight, water, and nutrients. Growing them in soil can also improve their flavor. You can also experiment with different varieties of green onions to find one that you particularly enjoy.
