Growing Green Onions Indoors: A Beginner’s Guide
Hey there, fellow plant enthusiasts! Ever find yourself needing just a sprinkle of green onion for a recipe and hating the thought of running to the store? Well, I’ve got a super easy and rewarding DIY project for you: growing green onions indoors! It’s surprisingly simple, requires minimal effort, and provides a constant supply of fresh green onions right at your fingertips. Trust me, once you start, you’ll wonder why you didn’t do it sooner.
What You’ll Need
Before we dive in, let’s gather our supplies. The beauty of this project is that you probably already have most of these items lying around:
* Green Onions: Obviously! You can use store-bought green onions. Look for ones with healthy, intact roots. The fresher, the better.
* A Glass or Jar: Any glass or jar will do, as long as it’s tall enough to hold the green onions upright and wide enough to accommodate a few of them. A mason jar, a drinking glass, or even a repurposed yogurt container works perfectly.
* Water: Tap water is fine, but filtered water is even better.
* Scissors or a Sharp Knife: For harvesting your green onions.
* Optional: Potting Soil and a Small Pot: If you want to transition your green onions to soil for longer-term growth.
* Optional: Liquid Fertilizer: A diluted liquid fertilizer can give your green onions a boost, but it’s not essential.
The Water Propagation Method: The Easiest Way to Start
This is the method I usually recommend to beginners because it’s incredibly straightforward and requires almost no effort.
Step 1: Prepare Your Green Onions
1. Cut the Green Onions: Using your scissors or knife, cut the green onions about 1-2 inches from the root end. You’ll be left with the white root end and the green tops. Don’t throw away the green tops! You can use them in your cooking right away.
2. Remove Any Yellowing or Damaged Parts: Inspect the root end and remove any yellowing, slimy, or damaged outer layers. This will help prevent rot and ensure healthy growth.
Step 2: Place in Water
1. Fill Your Glass or Jar: Fill your glass or jar with enough water to cover the roots of the green onions. Don’t submerge the entire white part of the onion; just the roots need to be in the water.
2. Arrange the Green Onions: Place the root ends of the green onions in the water, making sure they are standing upright. You can fit several green onions in one glass, but don’t overcrowd them.
Step 3: Find the Right Spot
1. Choose a Sunny Location: Place your glass of green onions in a bright, sunny location. A windowsill that receives at least 4-6 hours of sunlight per day is ideal. If you don’t have a sunny windowsill, you can use a grow light.
2. Monitor the Water Level: Check the water level daily and add more water as needed to keep the roots submerged. The water will evaporate over time, so it’s important to keep an eye on it.
Step 4: Change the Water Regularly
1. Refresh the Water: Every 1-2 days, change the water in the glass. This will help prevent algae growth and keep the water fresh.
2. Clean the Glass: While you’re changing the water, take a moment to clean the glass or jar. This will also help prevent algae growth.
Step 5: Watch Them Grow!
1. Observe the Growth: Within a few days, you should start to see new green shoots emerging from the top of the green onions. It’s amazing how quickly they grow!
2. Harvest as Needed: Once the green onions have grown to a desired length (usually a few inches), you can harvest them by cutting off the green tops with scissors. Leave about an inch or two of the green part so they can continue to grow.
The Soil Planting Method: For Longer-Term Growth
If you want to grow your green onions for a longer period and potentially get larger, more robust plants, you can transplant them into soil.
Step 1: Prepare Your Pot and Soil
1. Choose a Small Pot: Select a small pot with drainage holes. A 4-6 inch pot is a good size for a few green onions.
2. Fill with Potting Soil: Fill the pot with a good-quality potting soil. Make sure the soil is loose and well-draining.
Step 2: Transplant the Green Onions
1. Gently Remove from Water: Carefully remove the green onions from the water.
2. Make a Hole in the Soil: Use your finger or a small tool to make 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 root end of each green onion into the hole and gently cover the roots with soil. Make sure the white part of the onion is mostly buried, but the green part is exposed.
4. Water Thoroughly: Water the soil thoroughly after planting.
Step 3: Care for Your Potted Green Onions
1. Place in a Sunny Location: Place the pot in a bright, sunny location. Just like with the water propagation method, a windowsill that receives at least 4-6 hours of sunlight per day is ideal.
2. Water Regularly: Water the soil regularly, keeping it moist but not soggy. Allow the top inch of soil to dry out between waterings.
3. Fertilize Occasionally (Optional): If you want to give your green onions a boost, you can fertilize them every few weeks with a diluted liquid fertilizer. Follow the instructions on the fertilizer package.
Step 4: Harvest and Enjoy!
1. Harvest as Needed: Once the green onions have grown to a desired length, you can harvest them by cutting off the green tops with scissors. Leave about an inch or two of the green part so they can continue to grow.
2. Enjoy Your Fresh Green Onions: Use your homegrown green onions in your favorite recipes! They’re delicious in salads, soups, stir-fries, and as a garnish for just about anything.
Troubleshooting Tips
Even with the best intentions, sometimes things don’t go exactly as planned. Here are a few common issues you might encounter and how to address them:
* Yellowing Leaves: This can be caused by several factors, including overwatering, underwatering, lack of sunlight, or nutrient deficiencies. Make sure you’re providing adequate sunlight, watering properly, and fertilizing occasionally if needed.
* Slimy Roots: This is usually a sign of rot, which can be caused by stagnant water or bacteria. Change the water frequently and clean the glass or jar regularly to prevent rot. If the roots are severely affected, you may need to start with fresh green onions.
* Slow Growth: Slow growth can be caused by lack of sunlight, nutrient deficiencies, or cold temperatures. Make sure your green onions are getting enough sunlight and fertilize them occasionally. If it’s cold, try moving them to a warmer location.
* Algae Growth: Algae can grow in the water if it’s exposed to too much sunlight. Change the water frequently and clean the glass or jar regularly to prevent algae growth. You can also try using an opaque container to block out some of the light.
Tips for Success
Here are a few extra tips to help you succeed in growing green onions indoors:
* Start with Healthy Green Onions: Choose green onions with healthy, intact roots. Avoid ones that are yellowing, slimy, or damaged.
* Use Clean Water: Use clean, fresh water to prevent rot and algae growth.
* Provide Adequate Sunlight: Green onions need at least 4-6 hours of sunlight per day to thrive.
* Don’t Overwater: Overwatering can lead to rot. Allow the top inch of soil to dry out between waterings.
* Fertilize Occasionally: Fertilizing can help your green onions grow faster and stronger.
* Harvest Regularly: Harvesting regularly encourages new growth.
* Experiment: Don’t be afraid to experiment with different methods and techniques to find what works best for you.

Frequently Asked Questions (FAQ)
How long does it take for green onions to regrow?
Typically, you’ll start to see new growth within a few days of placing the green onion roots in water. Within a week or two, you’ll have a noticeable amount of new green shoots ready to harvest. The speed of growth depends on factors like sunlight, temperature, and the initial health of the green onion roots.
What’s the best way to harvest my green onions?
The easiest way to harvest is to simply snip off the green shoots with scissors, leaving about an inch or two of the white base intact. This allows the green onions to continue regrowing. Avoid pulling the entire plant out of the water or soil, as this will prevent further growth.
How often should I change the water?
It’s important to change the water every one to two days to prevent bacterial growth and keep the green onions healthy. Stagnant water can lead to rot and unpleasant odors. Use fresh, clean water each time.
Can I grow green onions indoors without sunlight?
While green onions can survive in low-light conditions, they will thrive with ample sunlight. Place your green onions near a sunny windowsill or under a grow light for optimal growth. If you don’t have access to natural light, a grow light can provide the necessary energy for photosynthesis.
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 lack of sunlight, nutrient deficiency, or overwatering. Ensure your green onions are receiving adequate sunlight and change the water regularly. If the problem persists, try adding a diluted liquid fertilizer to the water every few weeks. Also, make sure the roots are not rotting. If they are, cut away the rotten parts and use fresh water.
Can I plant my regrown green onions in soil?
Absolutely! Planting your regrown green onions in soil can lead to even more robust growth. Once the roots have developed well in water, you can transplant them into a small pot filled with well-draining potting mix. Water regularly and provide plenty of sunlight.
What kind of fertilizer should I use?
A diluted liquid fertilizer, such as a balanced 10-10-10 formula, works well for green onions. Follow the instructions on the fertilizer package and use it sparingly, about every two to three weeks. Over-fertilizing can damage the plants.
How long can I keep regrowing the same green onion roots?
With proper care, you can regrow green onions from the same roots for several weeks or even months. However, eventually, the roots will become less productive and the growth will slow down. At this point, it’s best to start with fresh green onion roots.
Are there any pests or diseases that affect indoor green onions?
Indoor green onions are generally resistant to pests and diseases. However, they can occasionally be affected by aphids or fungus gnats. If you notice any pests, try washing the plants with soapy water or using an insecticidal soap. To prevent fungal diseases, ensure good air circulation and avoid overwatering.
Can I use this method for other types of onions?
While this method works best with scallions and green onions, you can also try it with other types of onions, such as shallots or leeks. However, the results may vary, and the growth may not be as prolific.
Is it safe to eat green onions grown in water?
Yes, it is perfectly safe to eat green onions grown in water, as long as you maintain good hygiene practices. Change the water regularly to prevent bacterial growth and wash the green onions thoroughly before using them.
What if my green onions start to smell bad?
A foul odor usually indicates bacterial growth in the water. This is often caused by infrequent water changes or contaminated water. Immediately change the water and ensure you are using clean water going forward. If the odor persists, it may be necessary to discard the green onions and start with fresh roots.
Can I grow green onions indoors year-round?
Yes, you can grow green onions indoors year-round, regardless of the weather outside. As long as you provide adequate sunlight, water, and nutrients, you can enjoy a continuous supply of fresh green onions.
What are some creative ways to use my homegrown green onions?
The possibilities are endless! Use them as a garnish for soups, salads, and tacos. Add them to stir-fries, omelets, and dips. Incorporate them into sauces, marinades, and dressings. You can even use them to make green onion pancakes or scallion oil. Let your imagination run wild and experiment with different flavors and combinations.
