Regrowing Green Onions: A DIY Guide to Endless Scallions!
Hey there, fellow green thumb enthusiasts! Are you tired of buying green onions only to use a tiny bit and watch the rest wilt away in your fridge? Well, I’ve got a fantastic solution for you: regrowing them! It’s super easy, incredibly rewarding, and saves you money. Plus, it’s a great way to reduce food waste. 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:
* A bunch of green onions (obviously!). Look for ones with healthy roots still attached.
* A small glass or jar. I like to use mason jars, but any container that can hold water and the onion roots will work.
* Water (tap water is fine).
* Scissors or a sharp knife.
* (Optional) Potting soil and a small pot if you want to transplant them later.
* (Optional) Liquid fertilizer (for an extra boost).
The Basic Water Method: Regrowing in a Glass
This is the simplest and quickest way to regrow green onions. It’s perfect for beginners and requires minimal effort.
1. Prepare the Green Onions: Using your scissors or knife, cut the green onions about 1-2 inches above the roots. You want to leave enough of the white part attached to the roots so they can regrow. Don’t throw away the green tops you cut off! Use them in your cooking right away. I love adding them to salads, soups, and stir-fries.
2. Place in Water: Put the remaining green onion bases (the white part with the roots) into your glass or jar. Make sure the roots are submerged in water, but the cut ends of the green onion are above the water line. You don’t want the cut ends to rot.
3. Add Water: Fill the glass with enough water to cover the roots.
4. Find a Sunny Spot: Place the glass in a sunny location, like a windowsill. Green onions need sunlight to grow.
5. Change the Water Regularly: This is important! Change the water every 1-2 days to prevent bacteria growth and keep the water fresh. This will also help prevent any unpleasant odors.
6. Watch Them Grow!: Within a few days, you should start to see new green shoots emerging from the cut ends. It’s so exciting to watch them grow!
7. Harvest and Repeat: Once the green onions have grown to a usable length (usually a few inches), you can harvest them by cutting off the green tops as needed. Leave about an inch or two of the green part so they can continue to regrow. And the best part? You can repeat this process indefinitely!
Transplanting to Soil: For Longer-Term Growth
While the water method is great for quick regrowth, transplanting your green onions to soil will allow them to grow larger and stronger. This is what I do when I want a more substantial harvest.
Preparing for Transplanting
1. Let Them Grow in Water First: Follow steps 1-6 of the water method above. Let the green onions regrow in water for about a week or two, until they have a good amount of new green growth and the roots have also grown longer. This gives them a head start before transplanting.
2. Choose a Pot: Select a small pot with drainage holes. The size of the pot will depend on how many green onions you want to plant together. A 4-6 inch pot is usually sufficient for a few green onions.
3. Prepare the Soil: Fill the pot with good-quality potting soil. You can also add some compost or other organic matter to enrich the soil.
4. Water the Soil: Moisten the soil before planting. You don’t want it to be soaking wet, just damp.
Transplanting the Green Onions
1. Gently Remove from Water: Carefully remove the green onions from the water. Be gentle so you don’t damage the roots.
2. Make a Hole: Use your finger or a small tool to create a hole in the soil for each green onion. The hole should be deep enough to accommodate the roots.
3. Plant the Green Onions: Place the green onion in the hole, making sure the roots are covered with soil. The base of the green onion (where the white part meets the green part) should be just above the soil line.
4. Gently Pat the Soil: Gently pat the soil around the green onion to secure it in place.
5. Water Thoroughly: Water the newly transplanted green onions thoroughly.
6. Find a Sunny Spot: Place the pot in a sunny location. Green onions need at least 6 hours of sunlight per day.
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 encourage growth. Follow the instructions on the fertilizer packaging.
9. Harvest and Repeat: Just like with the water method, you can harvest the green tops as needed. Cut them off a few inches above the soil line, and they will continue to regrow.
Troubleshooting and Tips
Even though regrowing green onions is pretty straightforward, here are a few things to keep in mind:
* Rotting: If you notice the base of your green onions turning brown or mushy, it’s likely rotting. This is usually caused by keeping the cut ends submerged in water or not changing the water frequently enough. Remove the affected green onion immediately and start with a fresh one.
* Yellowing Leaves: Yellowing leaves can be a sign of overwatering or underwatering. Make sure the soil is consistently moist, but not soggy. If you’re using the water method, make sure you’re changing the water regularly.
* Slow Growth: Slow growth can be caused by lack of sunlight or nutrients. Make sure your green onions are getting enough sunlight and consider fertilizing them if you’re growing them in soil.
* 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.
* Choosing the Right Green Onions: When you’re buying green onions to regrow, look for ones that are firm and have healthy-looking roots. Avoid green onions that are wilted or have brown spots.
* Experiment with Different Varieties: There are many different varieties of green onions, so feel free to experiment and see which ones grow best for you.
* Don’t Overharvest: While it’s tempting to harvest all the green tops at once, it’s best to leave a few inches of the green part so they can continue to regrow.
* Consider the Climate: Green onions are relatively hardy and can tolerate a wide range of temperatures. However, they will grow best in temperatures between 60-70°F (15-21°C). If you live in a very hot or cold climate, you may need to adjust your growing practices accordingly.
* Successive 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.
* Using Fertilizer: While not essential, using a diluted liquid fertilizer can give your green onions a boost, especially if you’re growing them in soil. Look for a fertilizer that is specifically formulated for vegetables.
* Observe and Adjust: Pay attention to how your green onions are growing and adjust your care accordingly. Every environment is different, so what works for one person may not work for another.
Beyond the Basics: Advanced Tips for Green Onion Gurus
Want to take your green onion game to the next level? Here are a few advanced tips:
* Hydroponics: If you’re feeling adventurous, you can try growing your green onions hydroponically. This involves growing them in water without soil, using a nutrient-rich solution.
* Companion Planting: Green onions are known to be good companion plants for many other vegetables, such as tomatoes, peppers, and carrots. Planting them together can help deter pests and improve the overall health of your garden.
* Saving Seeds: If you let your green onions flower, they will produce seeds that you can save and plant to grow new green onions. This is a great way to create a sustainable supply of green onions for years to come.
* Growing Indoors Year-Round: With the right conditions, you can grow green onions indoors year-round. This is a great option if you live in a climate with harsh winters. You may need to supplement with artificial light to ensure they get enough sunlight.

Frequently Asked Questions (FAQ)
How long does it take to regrow green onions?
The speed at which your green onions regrow depends on several factors, including the amount of sunlight they receive, the temperature, and the quality of the water. Generally, you should start to see noticeable growth within a few days. Within a week or two, you’ll likely have enough green onion to harvest. Remember to change the water every few days to keep it fresh and prevent bacterial growth, which can slow down the process.
What part of the green onion do I need to regrow it?
You only need the white bulb end with the roots attached. When you’re using green onions in your cooking, cut off the green part, leaving about 1-2 inches of the white base intact. This base contains the root system and the dormant buds that will sprout new growth. Make sure the roots are still attached; without them, the green onion won’t be able to absorb water and nutrients.
Can I regrow green onions in soil instead of water?
Yes, absolutely! While water propagation is a great way to start the process and observe root growth, transplanting your green onions to soil will provide them with more nutrients and support stronger, more sustained growth. Once the roots are well-established in water (about an inch or two long), you can carefully plant the bulb in a pot filled with well-draining potting mix. Ensure the top of the bulb is just slightly above the soil surface. Water regularly, keeping the soil moist but not waterlogged.
How often should I water my regrowing green onions?
If you’re regrowing them in water, change the water every 1-2 days. This keeps the water fresh and prevents the buildup of bacteria. If you’ve transplanted them to soil, water them when the top inch of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot. The frequency of watering will depend on the climate and the type of soil you’re using.
What kind of light 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 light per day. If you don’t have a sunny window, you can supplement with a grow light. Insufficient light can result in leggy, weak growth.
Can I regrow green onions indefinitely?
While you can regrow green onions multiple times from the same base, the quality and vigor of the growth may diminish over time. After several harvests, the bulb may become depleted of nutrients. To ensure a continuous supply of fresh green onions, it’s a good idea to start new batches every few weeks. This way, you’ll always have a fresh supply ready to go.
What if my green onions start to turn yellow or brown?
Yellowing or browning leaves can indicate a few different issues. It could be due to overwatering, underwatering, lack of sunlight, or nutrient deficiency. Check the water or soil moisture and adjust accordingly. Ensure the green onions are receiving enough light. If the problem persists, consider adding a diluted liquid fertilizer to the water or soil to provide them with essential nutrients.
Can I eat the green onions that I regrow?
Yes, absolutely! The green onions you regrow are perfectly safe to eat. They will taste just like the ones you buy at the store. Simply snip off the green parts as needed for your cooking.
Are there any pests or diseases that affect regrowing green onions?
Regrowing green onions are generally pest and disease-resistant, especially when grown indoors. However, they can occasionally be susceptible to aphids or fungal diseases. If you notice any pests, try washing them off with a strong stream of water or using an insecticidal soap. To prevent fungal diseases, ensure good air circulation and avoid overwatering.
Can I regrow other vegetables using this method?
Yes, you can! This method of regrowing vegetables from scraps works well for other vegetables like celery, lettuce, bok choy, and even ginger. The basic principle is the same: use the base of the vegetable with the roots attached (or the potential for roots to grow) and provide it with water and sunlight. Experiment with different vegetables and see what you can regrow!
