What Are Green Onions?

Green onions, also known as scallions or spring onions, are a type of onion that is harvested before the bulb has fully formed. The entire plant, including the white root base and long green shoots, is edible.

Green onions have a milder flavor than mature onions and can be used in both raw and cooked dishes. When choosing green onions at the grocery store, look for ones that have crisp, vibrant green leaves. Avoid any brown or yellowing leaves, as this is a sign of age.

When To Plant Green Onions

When growing green onions in containers, there is no restriction on planting time. You can plant them indoors or outdoors, whenever you have the space and the time. However, if you’re growing them outdoors, it’s best to wait until all danger of frost has passed. When deciding when to plant green onion sets or transplants outdoors, take into account the maturity date stated on the seed packet or plant tag.

This will give you an idea of how long it will take the plants to reach harvest size. In general, bunching onion varieties mature more quickly than scallion varieties. When grown indoors under lights, onion plants can be started from seed eight to 10 weeks before the last frost date in your area.

Choosing A Pot

Choosing a pot for your green onion plants is an important step in ensuring their health and preventing disease. The pot should be no more than 6-8 inches deep and as wide as you like, with drainage holes in the bottom to allow excess water to escape.

If possible, choose a pot that is made of breathable material such as ceramic or terracotta, which will help to prevent the roots from becoming waterlogged. Once you have selected a pot, fill it with a well-draining potting mix and water deeply to moisten the soil. Then, gently dig a hole for each onion plant, taking care not to damage the roots. Finally, backfill the holes with soil and water well to settle the plants into their new home.

Planting Green Onions

Planting green onions from seeds is not the smartest idea because plants grown from seeds take the longest time to become mature enough to provide the harvest. Planting green onion sets or transplants is a much better option. Planting green onion sets are when you plant already grown onions that were started from seed and then transplanted into fields for growing to maturity.

Planting sets is faster because the onion has already made it through the germination stage and begun to form underground roots and above-ground growth. Therefore, less time is needed for the plant to produce a usable onion for harvest. When Should You Plant Green Onion Sets? The best time to plant green onion sets is in early spring as soon as the soil can be worked.

You want to make sure that the danger of frost has passed in your area. If you live in an area with a longer growing season, you can also plant in late summer for a fall crop.

This lack of bulb formation gives transplants their spindly shape.

How To Grow Green Onions


Green onions will grow best in an area that receives full sun, but they will also tolerate partial shade. If you are growing them indoors, place the pot near a sunny window.


Green onions prefer rich, well-drained soil with a pH of 6.0 to 6.8. To improve the drainage of your soil, mix in some organic matter such as compost or peat moss.

Keep the soil evenly moist throughout the growing season. Water your green onion plants deeply and regularly, about 1-2 inches per week. Be careful not to overwater, as this can lead to fungal diseases such as root rot.


Green onion plants are heavy feeders and will benefit from regular fertilization. Use a balanced fertilizer such as 10-10-10 according to the package directions. You can also side-dress the plants with compost or manure halfway through the growing season.


You can begin harvesting green onions when they are about 6-8 inches tall. Cut them off at soil level using a sharp knife. Be sure to leave at least 2 inches of growth so that the plant can continue to produce more onions.

Pests And Diseases

Green onion plants are relatively resistant to pests and diseases, but they can be affected by onion maggots, thrips, and white rot. To prevent problems, water the plants at the base to avoid getting water on the leaves. Also, remove any dead or diseased leaves from the plant.

With proper care, your green onion plants will provide you with a bountiful harvest of fresh onions all season long!
