Benefits of Growing Green Onions Indoors
There are many benefits to growing green onions indoors. Here are a few of the most important:
Availability and freshness

Growing green onions indoors is a very cost-effective way to get fresh herbs. You can start with a small investment in seeds or seedlings, and you’ll be harvesting your own green onions in no time.
Green onions don’t take up a lot of space, so they’re a great option for small apartments or homes. You can even grow them on a windowsill or on a countertop.
Green onions can be grown indoors year-round, so you’ll never have to go without them. This is especially helpful during the winter months when fresh herbs can be hard to find.
Essential Requirements for Growing Green Onions Indoors
There are a few essential requirements for growing green onions indoors. These include:
- Lighting: Green onions need at least 6 hours of sunlight per day. If you don’t have a sunny spot in your home, you can use a grow light.
- Temperature: Green onions prefer temperatures between 65 and 75 degrees Fahrenheit.
- Watering: Green onions need to be watered regularly, but don’t overwater them. The soil should be moist but not soggy.
- Soil: Green onions prefer a well-draining potting mix. You can buy a potting mix specifically for herbs, or you can make your own by mixing equal parts potting soil, perlite, and vermiculite.
- Fertilizer: Green onions don’t need a lot of fertilizer, but you can fertilize them every few weeks with a balanced liquid fertilizer.
Choosing Green Onion Varieties for Indoor Cultivation
There are many different varieties of green onions that can be grown indoors. Some of the most popular varieties include:
Scallions are a type of green onion that has a long, white stalk and a green top. They’re a good choice for indoor cultivation because they’re relatively easy to grow.
Bulbing onions are a type of green onion that forms a small bulb at the base of the plant. They’re a bit more challenging to grow indoors, but they can be very rewarding.
Welsh onions are a type of green onion that has a long, thin stalk and a mild flavor. They’re a good choice for indoor cultivation because they’re relatively easy to grow, and they don’t need a lot of sunlight.
Starting Green Onion Plants Indoors
There are two ways to start green onion plants indoors: from seeds or from seedlings.
Starting from seeds
To start green onions from seeds, you’ll need a seed tray or pot filled with potting mix. Sow the seeds about ¼ inch deep and water them lightly. The seeds should germinate in about 2–3 weeks.
Starting from seedlings
To start green onions from seedlings, you’ll need to purchase seedlings from a nursery or garden center. Plant the seedlings in a pot or container filled with potting mix. Water the seedlings lightly and place them in a sunny spot.
Caring for Green Onions Indoors
Once your green onion plants have started growing, you’ll need to care for them properly. Here are a few tips:
- Water regularly: Green onions need to be watered regularly, but don’t overwater them. The soil should be moist but not soggy.
- Provide sunlight: Green onions need at least 6 hours of sunlight per day. If you don’t have a sunny spot in your home, you can use a grow light.
- Fertilize every few weeks: Green onions don’t need a lot of fertilizer, but you can fertilize them every few weeks with a balanced liquid fertilizer.
- Rotate the plants: As the plants grow, rotate them so that all sides get equal sunlight.
- Pest and disease control: Green onions are relatively resistant to pests and diseases, but you may see some aphids or whiteflies. If you do, you can treat them with an insecticidal soap or neem oil.
Harvesting and Maintaining a Continuous Supply
You can start harvesting green onions when they’re about 6 inches tall. To harvest, simply cut the green tops off about 2 inches above the soil level. The roots will continue to grow, so you can keep harvesting the green tops for several weeks.
To maintain a continuous supply of green onions, you can replant the roots after harvesting. You can also start new plants from seeds or seedlings every few weeks.
