Green Onions, Scallions, and Spring Onions – What’s the Difference?
People often get confused about the differences between green onions, scallions, and spring onions. So, before we dive into the growing process, let’s clear up the confusion:
- Green Onions and Scallions
These terms are often used interchangeably and refer to the same plant. They’re harvested young, with long, slender green tops and small white bases. The terms green onions and scallions are simply different names for the same plant. - Spring Onions
These are more mature than green onions and scallions. They have a larger, more developed bulb and a milder flavor. The bulb is more pronounced compared to the small, underdeveloped bulb of green onions and scallions.
Why Grow Green Onions from Onion Bulbs?
Green onions are incredibly versatile and nutritious. They add a fresh crunch to salads, a subtle kick to soups, and a beautiful garnish to almost any dish. Growing them from onion bulbs offers numerous benefits:
- Reduces Waste
Using kitchen scraps to grow green onions is a great way to cut down on waste. - Saves Money
Instead of buying new green onions each time, you can simply regrow them from bulbs. - Easy and Space-Saving
This method is simple and doesn’t need much space, making it ideal for urban gardening or small spaces like my balcony. - Continuous Supply
With proper care, you can have a steady supply of green onions year-round. - Enhances Your Cuisine
Fresh, homegrown green onions add a vibrant flavor and personal touch to your cooking. My family can always taste the difference when we use green onions from our balcony garden—it just makes every dish a bit more special.
Step-by-Step Guide to Growing Green Onions
Growing green onions is incredibly easy. Here’s how you do it:
Preparing the Onion Bulbs
Start by prepping your onion bulbs. Place them in a shallow tray with the root end facing down. We used a large glass bakeware dish as our tray, which worked perfectly. Add just enough water to cover the bottom of the bulbs and let them soak for 24 hours. This kickstarts the root growth.
Cutting the Tops
After soaking, cut off the top part of the bulbs, leaving about half of the bulb intact. This helps the bulbs focus on growing roots and shoots.
Preparing the Container
Get your container ready. Fill a shallow tray or container with potting soil to a depth of about 1 inch. Make sure the soil is nice and moist.
Planting the Bulbs
Now, plant the bulbs. Put them in the soil with the root end down and make sure about half of the bulb is covered with soil, leaving the cut tops exposed.
Watering
Water is crucial. Keep the soil consistently moist by watering every 4 days, but be careful not to overdo it. You don’t want the bulbs to rot.

Growth and Harvest
Watch your green onions grow. In just a few days, you’ll see green shoots sprouting. Once they reach a good length, you can start harvesting. Just cut the green tops with scissors, and they’ll keep growing back for continuous harvests throughout the season.
Maintenance
Keep your green onions thriving with regular care. Water every 4 days and make sure they get plenty of sunlight. They need at least 6 hours of sunlight daily, so if you’re growing them indoors, place them near a sunny window or use a grow light. Regularly check for pests and remove any yellowing or dead leaves.
Practical Tips for Success
Here are some extra tips to help you succeed:
- Rotate Your Harvests
Plant new bulbs every few weeks to ensure a continuous supply. - Indoor vs. Outdoor
Green onions can be grown indoors all year round or outdoors in mild climates. Adjust your care routine based on the environment. - Soil Quality
Use high-quality potting soil to provide essential nutrients and ensure proper drainage. - Optimal Growing Seasons
While green onions can be grown year-round indoors, they thrive best during spring and fall when temperatures are cooler.
FAQs
