Let’s get started!
Regrow Green Onions: Never Buy Them Again!
Hey there, fellow frugal foodies! Are you tired of buying green onions only to use a tiny bit and watch the rest wilt away in your fridge? I’ve got a super simple, practically free, and incredibly satisfying DIY hack for you: regrowing green onions at home! Trust me, once you start, you’ll never look at a bunch of green onions the same way again. This is a game-changer!
What You’ll Need
Before we dive in, let’s gather our supplies. The beauty of this project is that you probably already have everything you need:
* A bunch of green onions (obviously!). Look for ones with healthy roots still attached.
* A small glass or jar. I like using mason jars, but any glass that can hold water and the onion roots will work.
* Water. Tap water is perfectly fine.
* Scissors or a sharp knife.
* Potting soil (optional, but recommended for long-term growth).
* A small pot or container (optional, for planting in soil).
The Water Propagation Method: Step-by-Step
This is the easiest and quickest way to regrow your green onions. It’s perfect for beginners and requires minimal effort.
1. Prepare the Green Onions: Take your bunch of green onions and cut off the green tops, leaving about 1-2 inches of the white and light green base with the roots attached. Don’t throw away the green tops! You can use them in your cooking right away. I usually chop them up and add them to salads, soups, or stir-fries.
2. Place 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 onion is submerged. We want the roots to be in the water, but the base of the onion to be exposed to air to prevent rotting.
3. Find a Sunny Spot: Place the jar with the green onion bases in a sunny spot, like a windowsill. Green onions need sunlight to grow, so the more light they get, the faster they’ll regrow.
4. Change the Water Regularly: This is important! Change the water every 1-2 days to keep it fresh and prevent bacteria from growing. This will also help to provide the onions with fresh oxygen. 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’ll start to see new green shoots emerging from the tops of the onion bases. It’s so exciting to watch! You’ll be amazed at how quickly they grow.
6. Harvest and Repeat: Once the green shoots have grown to a usable length (usually a few inches), you can harvest them by cutting them off with scissors. Leave about an inch or two of the green shoots so they can continue to grow. And guess what? You can repeat this process over and over again!
The Soil Planting Method: For Long-Term Green Onion Production
While the water propagation method is great for quick regrowth, planting your green onions in soil will allow them to grow larger and stronger, and potentially even produce new bulbs.
Preparing for Planting
Before we get our hands dirty, let’s prep our green onion bases for planting.
1. Root Development (Optional, but Recommended): You can start by placing the green onion bases in water as described above for a few days to encourage root growth. This will give them a head start when you plant them in soil. I find that they establish themselves much better this way.
2. Choose Your Pot and Soil: Select a small pot or container with drainage holes. Drainage is crucial to prevent the roots from rotting. Use a good quality potting soil that is well-draining. I like to use a mix of potting soil and compost for extra nutrients.
Planting Your Green Onions
Now for the fun part!
1. Fill the Pot: Fill your pot with potting soil, leaving about an inch of space at the top.
2. Plant the Green Onion Bases: Make a small hole in the soil for each green onion base. Plant the bases so that the roots are completely covered with soil, and the white part of the onion is partially buried. You can plant several green onion bases in the same pot, spacing them about an inch or two apart.
3. Water Thoroughly: Water the soil thoroughly after planting, until water drains out of the drainage holes.
4. Find a Sunny Spot: Just like with the water propagation method, place the pot in a sunny spot. Green onions need at least 6 hours of sunlight per day to thrive.
5. Water Regularly: Keep the soil consistently moist, but not soggy. Water when the top inch of soil feels dry to the touch.
6. Fertilize (Optional): To encourage even more growth, you can fertilize your green onions every few weeks with a diluted liquid fertilizer. I like to use a balanced fertilizer, following the instructions on the label.
7. Harvest and Enjoy!: Once the green shoots have grown to a usable length, you can harvest them by cutting them off with scissors. You can also harvest the entire plant by pulling it up from the soil. If you harvest the entire plant, you can replant another green onion base in its place.
Troubleshooting Tips
Even with the best intentions, sometimes things don’t go exactly as planned. Here are a few common problems you might encounter and how to fix them:
* Rotting: If the base of your green onion starts to rot, it’s usually because it’s been sitting in too much water. Make sure that only the roots are submerged in water, and change the water regularly. If you’re planting in soil, make sure the soil is well-draining and not waterlogged.
* Slow Growth: If your green onions aren’t growing as quickly as you’d like, it could be due to a lack of sunlight or nutrients. Make sure they’re getting plenty of sunlight, and consider fertilizing them with a diluted liquid fertilizer.
* Yellowing Leaves: Yellowing leaves can be a sign of overwatering or underwatering. Check the soil moisture and adjust your watering accordingly. It could also be a sign of nutrient deficiency, so consider fertilizing them.
* Pests: Green onions are generally pest-resistant, but occasionally they can be affected by aphids or other small insects. If you notice any pests, you can try spraying them with a mixture of water and dish soap.
Extra Tips and Tricks
Here are a few extra tips to help you get the most out of your green onion regrowing adventure:
* Experiment with Different Varieties: There are many different varieties of green onions, each with its own unique flavor and texture. Try experimenting with different varieties to see which ones you like best.
* Succession Planting: To ensure a continuous supply of green onions, start new batches every few weeks. This way, you’ll always have fresh green onions on hand.
* Use Green Onion Flowers: If your green onions start to flower, don’t throw them away! The flowers are edible and have a mild onion flavor. You can use them in salads, soups, or as a garnish.
* Store Harvested Green Onions Properly: To keep your harvested green onions fresh for longer, wrap them in a damp paper towel and store them in a plastic bag in the refrigerator.
* Get the Kids Involved: This is a great project to do with kids! It’s a fun and educational way to teach them about gardening and where their food comes from.
So there you have it! Everything you need to know to regrow green onions at home. It’s a simple, rewarding, and sustainable way to add fresh flavor to your meals. Happy growing! I hope you enjoy this as much as I do. It’s a small thing that makes a big difference in my kitchen and my wallet!

Frequently Asked Questions (FAQ)
How long does it take for green onions to regrow?
Generally, you’ll start to see new growth within a few days. Within a week, you should have a noticeable amount of fresh green shoots ready to harvest. The speed of regrowth depends on factors like the variety of green onion, the amount of sunlight it receives, and the water quality.
How much of the green onion should I leave when I cut it?
Leave about an inch or two of the white bulb and roots intact. This is crucial because the new growth will emerge from this base. If you cut too close to the roots, the green onion might not regrow.
What kind of water should I use?
Tap water is generally fine, but if your tap water is heavily chlorinated, it’s best to let it sit out for a few hours before using it. This allows the chlorine to dissipate. Filtered water is also a good option. Avoid using distilled water, as it lacks the minerals that plants need to thrive.
How often should I change the water?
Change the water every one to two days to prevent bacterial growth and keep the roots healthy. Stagnant water can lead to rot and hinder regrowth. When you change the water, gently rinse the roots to remove any debris.
Where should I place the green onions for optimal growth?
Green onions need sunlight to grow, so place them in a bright location, such as a windowsill that receives several hours of direct sunlight each day. If you don’t have a sunny windowsill, you can use a grow light to supplement the natural light.
Can I plant the regrown green onions in soil?
Yes, absolutely! Once the roots have grown a few inches long, you can transplant the green onions into a pot filled with well-draining potting mix. This will allow them to develop larger bulbs and potentially even flower. When planting in soil, make sure to bury the white bulb completely, leaving the green shoots exposed.
How often should I water green onions planted in soil?
Water them regularly, keeping the soil consistently moist but not waterlogged. Check the soil moisture by sticking your finger into the soil. If the top inch feels dry, it’s time to water.
Can I use fertilizer to help them grow?
Yes, you can use a diluted liquid fertilizer every few weeks to boost growth, whether they are in water or soil. Choose a balanced fertilizer or one specifically formulated for herbs. Follow the instructions on the fertilizer package carefully to avoid over-fertilizing, which can damage the plants.
What if my green onions start to turn yellow or brown?
Yellowing or browning leaves can indicate several issues. It could be due to overwatering, underwatering, lack of sunlight, or nutrient deficiencies. Adjust your watering schedule, move the green onions to a brighter location, and consider adding fertilizer. If the roots are rotting, discard the affected green onions and start with fresh ones.
How long can I keep regrowing the same green onion base?
You can typically regrow green onions from the same base several times, but eventually, the regrowth will slow down or stop. This is because the nutrients in the base are depleted. When this happens, it’s time to start with a fresh set of green onions.
Are there any pests or diseases that affect regrown green onions?
Green onions are generally pest-resistant, but they can occasionally be affected by aphids or other common garden pests. If you notice any pests, you can try washing them off with a strong stream of water or using an insecticidal soap. Diseases are less common, but good hygiene and proper watering can help prevent them.
Can I regrow other vegetables using this method?
Yes, there are several other vegetables that you can regrow from scraps, including lettuce, celery, bok choy, and garlic. The specific methods may vary slightly, but the basic principle of using the base or root end to generate new growth remains the same.
Is regrowing green onions at home organic?
Yes, regrowing green onions at home can be considered organic, especially if you use organic potting mix and avoid using synthetic fertilizers or pesticides. It’s a great way to have access to fresh, organic herbs without having to rely on store-bought options.
What are the benefits of regrowing green onions at home?
The benefits are numerous! You save money, reduce food waste, have a constant supply of fresh herbs, and enjoy the satisfaction of growing your own food. It’s also a fun and educational activity for kids and adults alike. Plus, it’s a small step towards a more sustainable lifestyle.
