Growing green onions in containers is an easy way to always have fresh green onions on hand. They are great for adding flavor to any dish without having the hassle of going out and buying them every time you need some. Here’s your comprehensive guide to growing green onions in containers!
It’s quite easy to grow green onions in containers
Green onions are an everyday garden staple because they’re a cinch to grow. But, did you know if you live in a cold climate or tiny apartment, you can easily grow green onions indoors in containers?
One of the best parts of growing green onions is that you can regrow them from their bulbs time after time…indefinitely! There’s no need to buy seeds or bulbs for each planting, making it a very rewarding (and affordable) gardening experience.
Container gardening, in general, can be a terrific way for anyone to grow vegetables and herbs!
Tip: Check out how common garden vegetables, such as carrots, green beans, and onions, kale, beets (and the list goes on!) grow in containers. I also have some great tips to get plentiful yields from blueberries and strawberries grown in containers. You can even grow perennial flowers like lavender in those container gardens too!

What are green onions?
Because green onions are also called scallions and spring onions, there’s a lot of confusion about them. Are all of these “varieties” the same thing? Are they different?
Green onions and scallions are actually the same things. They’re the immature leaves (which look like green stalks) of a bulb in the onion family. It’s worth mentioning that the bulbs of scallions never get big and round like the bulbs of other onions.
Spring onions, on the other hand, are cousins to green onions. They grow from a more typical-looking onion bulb.
Advantages To Growing Green Onions In Containers
Growing green onions in containers allows you to grow them inside or outside. This can be especially helpful if you want to move your green onions indoors for the cold months.
If you live in a condo or apartment and don’t have space for a garden, container gardening allows you to still grow your own vegetables.
Can you grow green onions in pots?
Yes! Green onions don’t take up a lot of space (although they CAN spread if you let them run wild). Plus, they don’t have deep roots, which makes them ideal for growing in containers.
Can you regrow green onions?
One of my favorite things about green onions is that you can harvest your green onion leaves and then regrow another harvest from the same bulbs! Regrowing vegetables from kitchen scraps is an easy and cost-effective way to have a steady supply of fresh homegrown food at your fingertips.
Tips For Planting Green Onions
Some vegetables and herbs grow best from seeds, while others do better growing from cuttings. Green onions take a long time to grow from seeds, but they grow easily (and quickly!) from the bulbs.
In fact, they do so well growing from bulbs that my preferred method for growing them is to buy green onions from the grocery store to use in my recipes. When I use them, I trim off what I need and leave about 1-2 inches of the white portion at the bottom (the bulbs) to plant.
How To Grow Green Onions In Containers
The process of growing green onions is super simple! They do all the hard work while you sit back and count down the days until you can harvest them.
Actually, there are two ways you can grow green onions: in water or in soil. Growing green onions in water is a great way to grow them. It’s fast and easy and lets the kids see how vegetables grow from cuttings.
However, if you really want to have a regular supply of fresh, homegrown green onions, I recommend starting the roots in water and then planting the bulbs in the soil. The plants will be larger and produce better yields. You’ll be able to harvest your green onions and the plants will quickly sprout up more stalks.
To grow your green onions in water, add a small amount of water to a clean jar. You want just enough water to cover the bulbs but keep the tops above water. Add a little more water every few days and replace the water if it starts to look cloudy.
Keep the jar out of direct sunlight to prevent algae from growing!
If you want the ability to continuously harvest your green onions, growing them in soil is the better option.
Use a pencil to poke holes into the soil. Insert the cuttings in the soil but keep the tops above the soil.
Frequently Asked Questions About Growing Green Onions At Home In Containers
Here are some questions I frequently get about planting veggies and herbs indoors. I had some of these questions myself and wanted to make sure I could help you all!
When can I plant green onions in pots?
If you’re growing green onions indoors, you can plant them any time of the year. If you want, you can stagger plantings to have a steady supply of fresh green onion ready to eat.
What kind of pot should I use?
Onions, in general, have pretty shallow roots, and green onions follow that pattern. The best kind of container would be a wide, shallow pot so that you have space to grow multiple bulbs and have about 2 inches or so between them.
How much light do green onions need?
Although your green onions can tolerate some shade, keep them in a bright window that gets at least 4 hours of sunlight.
How often do i need to water?
Keep the soil moist to slightly on the dry side. Water when the top inch of the soil gets dry. Avoid overwatering because the roots will rot.
What type of soil do green onions need?
Green onions need well-draining soil that’s rich in nutrients.
Do you need to use fertilizer?
Green onions do need nutrient-rich soil. If you add manure or compost to your soil, there’s no need to also add fertilizer. However, if you don’t, you can use a balanced liquid fertilizer once a month.
How And When To Harvest Green Onions
Green onions are all ready to harvest when they’re about 10 inches tall and 1-inch in diameter. Although you should be able to pull them out of the soil easily, you can also just cut off the stalk while leaving the bulbs alone. Cut where the stalk is still a little green so that the plant can grow a new stalk.
