Regrowing Green Onions: A Simple DIY Guide
Hey there, fellow green thumb enthusiasts! Are you tired of constantly buying green onions only to use a small portion and toss the rest? Well, I’ve got a fantastic, super-easy DIY hack for you: regrowing green onions right in your own kitchen! It’s a sustainable, cost-effective, and surprisingly rewarding way to always have fresh green onions on hand. Trust me, once you start, you’ll never look at a bunch of green onions the same way again.
What You’ll Need
Before we dive in, let’s gather our supplies. This is a pretty low-key project, so you probably already have most of these items:
* A bunch of green onions (obviously!). Look for ones with healthy roots still attached.
* A small glass or jar. A mason jar works great, but any container that can hold water and the green onion roots will do.
* Water. Tap water is perfectly fine.
* Scissors or a sharp knife.
* (Optional) Potting soil and a small pot if you want to transition to soil later.
* (Optional) Liquid fertilizer (balanced, diluted) if you want to give your green onions an extra boost.
The Regrowing Process: Two Methods
There are two main ways to regrow green onions: in water or in soil. I’ll walk you through both, starting with the water method, which is the easiest for beginners.
Method 1: Regrowing in Water
This is the simplest and quickest way to get started. It’s perfect if you just want a steady supply of green onions without the hassle of potting soil.
Step-by-Step Instructions:
1. Prepare the Green Onions: Using your scissors or knife, cut the green onions about 1-2 inches from the root end. You want to leave enough of the white and light green part attached to the roots. 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 it covers the entire white part of the green onion. You want the roots to be submerged, but the cut end should be exposed to air.
3. Find a Sunny Spot: Place the jar in a sunny location, like a windowsill. Green onions need sunlight to grow, so the more light they get, the better. A south-facing window is ideal, but any window that gets a good amount of sunlight will work.
4. Change the Water Regularly: This is crucial! Change the water every 1-2 days to prevent bacteria growth and keep the water fresh. Stagnant water can lead to rot and kill your green onions. I usually just dump out the old water, rinse the jar, and refill it with fresh water.
5. Watch Them Grow: Within a few days, you should start to see new green shoots emerging from the cut end. It’s pretty amazing to watch! The growth rate will depend on the amount of sunlight and the overall health of the green onions.
6. 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 grow. And that’s it! Just keep changing the water and providing sunlight, and you can keep harvesting green onions for weeks, even months. Eventually, the growth will slow down, and you’ll need to start with fresh green onions.
Method 2: Regrowing in Soil
If you want a more permanent solution and potentially larger, more robust green onions, you can transplant them into soil. This method requires a little more effort, but it’s still pretty simple.
Step-by-Step Instructions:
1. Follow Steps 1-4 from the Water Method: Start by preparing the green onions and placing them in water as described above. This allows the roots to rehydrate and start growing before you transplant them.
2. Prepare Your Pot: Choose a small pot with drainage holes. Fill it with good-quality potting soil. I like to use a mix that’s specifically formulated for vegetables, but any general-purpose potting soil will work.
3. Plant the Green Onions: After a few days of growing in water, gently remove the green onions from the jar. Make a small hole in the soil with your finger or a pencil. Plant the green onion roots in the hole, making sure the white part is buried and the green part is above the soil.
4. Water Thoroughly: Water the soil thoroughly after planting. You want the soil to be moist but not soggy.
5. Find a Sunny Spot: Just like with the water method, place the pot in a sunny location.
6. Water Regularly: Keep the soil consistently moist, but don’t overwater. Overwatering can lead to root rot. I usually check the soil moisture every day or two and water when the top inch of soil feels dry.
7. Fertilize (Optional): To give your green onions an extra boost, you can fertilize them every few weeks with a diluted liquid fertilizer. Follow the instructions on the fertilizer label. I usually use a balanced fertilizer (like 10-10-10) diluted to half strength.
8. Harvest and Repeat: Once the green onions have grown to a usable length, 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 grow. With proper care, your green onions can continue to grow in soil for a long time.
Troubleshooting Tips
Even with the best intentions, sometimes things don’t go as planned. Here are a few common issues you might encounter and how to fix them:
* Yellowing Leaves: Yellowing leaves can be a sign of overwatering, underwatering, or lack of nutrients. Make sure you’re watering properly and consider fertilizing if you haven’t already. Also, ensure they are getting enough sunlight.
* Rotting Roots: Rotting roots are usually caused by stagnant water or overwatering. Make sure you’re changing the water regularly (if growing in water) and that the soil is well-draining (if growing in soil).
* Slow Growth: Slow growth can be caused by lack of sunlight, lack of nutrients, or cold temperatures. Make sure your green onions are getting enough sunlight and consider fertilizing. If it’s cold, try moving them to a warmer location.
* Pests: While green onions are relatively pest-resistant, they can sometimes be affected by aphids or other small insects. If you notice pests, try spraying them with a mixture of water and dish soap.
Extra Tips for Success
Here are a few extra tips to help you get the most out of your green onion regrowing project:
* Start with Healthy Green Onions: The healthier the green onions you start with, the better your chances of success. Look for ones with firm, white bulbs and healthy-looking roots.
* Don’t Overcrowd: If you’re growing multiple green onions in the same container, make sure they have enough space to grow. Overcrowding can lead to competition for resources and stunted growth.
* Experiment with Different Varieties: There are many different varieties of green onions, each with its own unique flavor and characteristics. Experiment with different varieties to find your favorites.
* Use Filtered Water: While tap water is generally fine, using filtered water can help prevent mineral buildup and keep your green onions healthier.
* Rotate Your Crops: If you’re growing green onions in soil, consider rotating your crops every few months to prevent soil depletion.

Frequently Asked Questions (FAQ)
How long does it take for green onions to regrow?
Typically, you’ll start to see noticeable regrowth within a few days. Within a week, you should have a significant amount of new green growth that’s ready to harvest. The speed of regrowth depends on factors like sunlight, water quality, and temperature. Warmer temperatures generally promote faster growth. Don’t be discouraged if it takes a little longer in cooler climates. Just be patient and ensure they are getting enough light.
What kind of container should I use?
Almost any container that can hold water will work. A glass jar, a plastic cup, a ceramic mug, or even a small bowl are all suitable options. The key is to choose a container that’s stable and won’t easily tip over. Make sure the container is clean to prevent the growth of bacteria or mold. A clear container allows you to easily monitor the water level and the root growth.
How much of the green onion should I leave when replanting?
Leave about 1-2 inches of the white bulb and the very bottom of the green stalks attached. This provides the necessary energy and structure for regrowth. Cutting too close to the bulb can damage it and prevent it from sprouting. The roots are essential for absorbing water and nutrients, so be careful not to damage them during the cutting process.
How often should I change the water?
Changing the water every 1-2 days is generally recommended. This helps to prevent the water from becoming stagnant and harboring bacteria. Fresh water provides the green onions with the oxygen they need to thrive. If you notice the water becoming cloudy or discolored, change it immediately.
How much sunlight do green onions need to regrow?
Green onions need at least 6 hours of sunlight per day to thrive. Place your container in a sunny windowsill or under a grow light. If you don’t have access to direct sunlight, a grow light can provide the necessary light for healthy growth. Rotate the container regularly to ensure that all sides of the green onions receive equal amounts of light.
Can I plant the regrown green onions in soil?
Yes, absolutely! Once the green onions have developed a good root system in water, you can transplant them into soil. This will allow them to grow even larger and produce more green onions. Choose a well-draining potting mix and plant the green onions at the same depth they were growing in water. Water them regularly and fertilize them every few weeks.
What if my green onions start to turn yellow or brown?
Yellowing or browning leaves can indicate a few different problems. It could be due to overwatering, underwatering, lack of sunlight, or nutrient deficiency. Check the water level and make sure the soil is not waterlogged. Ensure that the green onions are receiving enough sunlight. If the problem persists, try adding a diluted liquid fertilizer to the water or soil.
Can I regrow other vegetables using this method?
Yes, you can! This method works well for other vegetables like celery, lettuce, and bok choy. The basic principle is the same: place the base of the vegetable in water and allow it to regrow. Experiment with different vegetables and see what works best for you.
How long can I keep regrowing the same green onion base?
With proper care, you can regrow the same green onion base multiple times. However, the regrowth may become less vigorous over time. Eventually, the base will exhaust its energy reserves and stop producing new growth. When this happens, it’s time to start with a fresh green onion base.
Is it safe to eat regrown green onions?
Yes, it is perfectly safe to eat regrown green onions, as long as you follow proper hygiene practices. Wash the green onions thoroughly before eating them. If you notice any signs of mold or bacteria growth, discard the green onions immediately.
