Can I Freeze Green Onions, Growing Instructions

Can I Freeze Green Onions, Numerous varieties of onions go by the name “green onion.” You can be sure you’ll always have access to the freshest, most flavorful alliums by learning how to grow green onions! 

Authentic green onions are Fistulosum allium, also known as green onions, bunching onions, or simply scallions. We’ll concentrate the majority of our attention on these today.

Standard onions, Allium, have a red or white bulb and can be harvested before the bulbs form, and the young stalks can be used like green onions. In addition, there is a prolific allium known as Egyptian onions or tree onions.

The long, green leaves on these onions are the reason they are harvested. They grow in dense clusters made up of several stems and bulbs joined together, and they have a propensity to disperse over time.

We have a ton of information to share if you’re wondering where to find all of these delicious varieties of green onions. We’ll discuss how to grow green onions from seeds, young plants, or other sources. Let’s get started by discussing how to sow green onion seedlings in your garden.

A Guide to Scallions A. fistulosum Allium

also known as bunching onions, scallions, Welsh onions, Japanese bunching onions, or green onions. Before they were well-liked in China and Egypt, they were probably foraged in the wild.

Green onions resemble regular onions in appearance.

c. allium. They are typically 1-2 feet tall and have tall, green stalks. At their base, they have thin, white bulbs that never grow large enough to form onions. Scallions will bolt to seed in hot weather, producing a globular cluster of tiny white flowers.

Scallion leaves can be harvested for a number of years in mild climates because green onions are perennials. Scallions are edible in their entirety, even the flowers. Scallions that are thinner will taste milder, whereas onions that are thicker will taste stronger and hold up better to cooking.

Intriguingly, you can identify the variety of scallions by examining the cross-section of the leaves where they turn white: if the cross-section is D-shaped or flat, the variety is a cepa. However, if it has an O shape, it is a fistulousum.

Green Onion Planting

Eight to ten weeks prior to the last frost, start indoor seeding. The seeds should sprout in 7 to 14 days if you keep them moist. When directly sowing seeds, do so when the temperature is at least 50 degrees Fahrenheit, and plant each seed 14 inches deep. A

mat for heating seeds is able to aid in germination. Seedlings should be thinned to be 2 inches apart or left to naturally separate.

Upon being ready to transplant the seedlings,

the seedlings are separated. If desired, you can continue planting throughout the spring, summer, and fall. Transplanting should be started 2–4 weeks before your last frost date in the spring. Seedlings should be spaced one to two inches apart, with rows six inches apart. Because green onions may help keep pests away from your garden, think about interplanting them with your other crops. Because onion plants have shallow roots, irrigation should be done frequently.

2 to 4 weeks prior to the last date of frost, plant traditional onion sets. They should be treated similarly to a transplanted green onion, but be sure to space them at least 2 inches apart to allow for bulb growth. Although an Allium cepa will eventually produce a larger onion bulb, the green leaves can still be used in the same ways as green onions.

Let’s learn how to care for green onions so they can mature now that you are more knowledgeable about their varieties. Let’s go over some more specifics regarding scallions’ care.

heat and the Sun

Plant in a spot that receives at least 6 hours of direct sunlight. In zones 6 through 9, scallions grow best, and they prefer temperatures of 60 to 75 degrees Fahrenheit to flourish. If you intend to grow scallions all winter, mulch the bulbs you planted in the fall with straw or other organic material to keep weeds out and to protect them from the cold.

You might want to plant your green onions in the garden where they will get afternoon shade if you live in a zone warmer than 9. It is definitely possible to grow scallions in hot climates because onions prefer full sun!

Another option is to grow green onions indoors, especially if your winters are chilly. You can harvest scallions all through the winter and well into the spring if you give them plenty of light and warmth during the dark months.

Humidity and water

The best time to water is in the morning to prevent soil moisture evaporation. Additionally, this enables foliage to dry out during the day so that it is less susceptible to disease.

Scallions are drought-sensitive. Per week, aim for 1 inch of water. Use sponge hoses or drip watering. Another effective technique is irrigation in a ditch, or “furrow.” Dig a long trench in the ground about an inch or two away from your plants. Flood the trench to provide moisture for the bulbs.

You will need to irrigate more frequently if your soil is sandy. Plants grow more slowly in mild climates or cooler seasons, necessitating less watering.

Loamy, fluffy, and well-balanced soil is preferred by scallions. If your soil is poor, amend it at least six inches deep with organic material, such as compost. Even though onion bulbs can grow in clay soil, they struggle if it gets too dry, and the soil might have a bit too much moisture for them. It is best to amend the soil so that good drainage is possible while still maintaining soil moisture.

The ideal soil pH range for growing scallions is between 6.0 and 7.0. If you plant these bulbs close to tomatoes or other solanaceous plants, they will survive because they can tolerate soil pH levels that are a little lower than 6.0. These might have trouble getting started if the soil is overly alkaline.


You should fertilize scallion plants on a regular basis with a nitrogen-rich amendment because they are leafy greens. Consider watering your plants with a liquid fertilizer during the growing season to provide nutrients at the time when they are most needed.

Examples of liquid fertilizers include fish fertilizer and comfrey tea. Use granular fertilizers that will slowly release into the soil for a longer-term fix. Find one that has a high nitrogen content (the “N” in N-P-K). Add a top-dressing of rich compost, if desired.


Pruning is typically only done to prepare trees for harvest. Plants should be left alone until it’s time to harvest them, with the exception of trimming for aesthetic reasons, such as removing wilted leaves.

Trim the flower stalk if your green onions are about to bolt and you want to prevent seed drop. Leaf wilt is a common occurrence during flowering as well. Trimming the bud and stalk (also known as the “onion scape”) early will focus your plant’s energy on growing leaves.

Allow the flowers to fully open if you want to collect seed. The flowers on onions are quite beautiful. They produce a sizable umbel that resembles a ball. When the flowers have finished blooming, tightly fasten a paper bag to the stalk. The seeds are minuscule. Once the stalk starts to droop, cut it off and place it somewhere for the flower’s head to dry out and its seeds to fall.


Bulb or “set” propagation is one method. Sets work best when planted in the garden in the late fall and overwintered there. They’ll begin pushing up new growth in the spring.

Additionally, you may use nursery starters of allium to produce the green onion stalks and plant them. Remember that only a fistulosum Allium yields tree-green onions devoid of onion bulbs. The flavor of true scallions is milder than that of cepa, which tastes more like onion.

Green onion plants purchased from a store come with rooted bulbs that can be easily turned into green onions again. Every few weeks, they’ll gladly grow tall, emerald leaves as a bonus crop for you. If you want to save the young green onion bases from the supermarket and plant them in moist soil with a T5 light, you’ll see new growth quickly appear because this method works both indoors and outdoors.

Starting from seeds is also unquestionably a possibility. For a wide range of bunching onion and scallion species, seeds are readily available. To sow seed, adhere to the instructions in the “planting” section above.

Gathering and Keeping

Are you unsure of what to do with mature green onions? Let’s discuss how to gather the plant and prepare your tasty scallions!

Harvesting: As soon as they are large enough to be used, begin to harvest your green onions. Even smaller seedlings can be harvested, but the best time to harvest is when the bulbs are white and have a diameter of about the size of a pencil. In fact, you can plant and harvest onion seeds.

as microgreens and onions if you choose to!

If you want to eat the mild white bulb, either dig up the entire plant or cut the stem just above the soil line and let it grow. a spotless pair of kitchen shears or

garden shears suitable for this. Using the latter method, you can harvest continuously by leaving the plant’s roots and base in the ground and cutting off the stalks an inch or two above the soil line. More palatable shoots will emerge from the plant very soon!

Harvest the green leaves as soon as they are ready and use them like scallions when growing conventional bulb onions as green onions. From the second growing season onward, Egyptian onions should be harvested.

The stalk and unopened bud of a bolting plant are referred to as an “onion scape.” Onion scapes can be a fantastic addition to a stir-fry or other dish and are equally as tasty as the leaves.

Green onions should be stored in a jar with just enough moisture to cover the bulbs halfway in the refrigerator. When harvesting stalks devoid of bulbs, place the harvested stalks in a plastic storage bag, wrapped in a paper towel. Alternately, cut them into pieces and store them in the fridge in a plastic bag. When stored using these techniques, moisture is your green onions’ worst enemy, so the paper towel is essential to keep the bulbs and leaves dry.

Green onions should be thoroughly dried before freezing after being rinsed. This is best if you intend to use them in cooked food rather than as a garnish, because the texture will often be a bit mushy when they thaw out.

If you possess a dehydrator, dehydrating and powdering the stalks is a fantastic option for long-term storage.


Let’s now talk about some issues that could arise while growing scallions. Since scallions are members of the Allium family, they frequently deter pests with their pungent smell, despite being vulnerable to a few easily treatable pests and diseases.

Increasing Issue Excessive moisture can lead to some forms of this in your developing scallions.

root decay. Make sure to only give them the right amount of moisture so they can grow. To keep the soil moist, use an irrigation system or a drip hose. The converse of that is that inadequate moisture Make sure they are not thirsty, as this can result in leaf wilting or yellowing.

When it is too warm, your onions will flower and bolt. Pay attention to when to plant them in your growing zone.

Competing with weeds can make scallions grow small, become weak, or even pass away. Regularly inspect your plants and remove any weeds that are nearby, especially those that are in the root zone. Weeds can also be reduced by mulching.


Thrips and aphids are frequent pests that can be eliminated with a strong stream of water from a hose. Use insecticidal soap or neem oil if they don’t go away. Pyrethrin can be used to treat severe infestations.

Onion worms can be avoided in the garden by using crop rotation. Floating row covers can also act as a deterrent for flies that lay onion maggot eggs. Onion maggots are naturally preyed upon by beneficial nematodes. The majority of pyrethrin insecticides that control thrips also work to control onion maggots.

Snails and slugs are a problem, but they are also simple to handle. For some of these annoying pests, you can set up a beer trap among your crops. Snails and slugs will be drawn in by the aroma of the beer and drowned as long as the depth is about the same as a pie pan. A natural slug and snail bait is a fantastic alternative to beer traps for keeping pests away from your greens.


Black rot can result in rot or mold at the plant’s base and wilted, yellow leaves. Remove and discard any infected plants you find. A few years should pass before planting any alliums there. A healthy crop rotation is crucial for the health of your allium.

Downy mildew on onions (Peronospora destructor) may result in erratic spotting and shrinkage. To treat, use copper fungicides, but rotate your allium crops in that bed every three years.

The botrytis leaf blight results in white spots on the plant’s leaves, wilting, and possible death. This occurs most frequently when plants are wet for at least 20 hours in cool weather. Ensure adequate airflow so that plants can dry out. Alternate copper and sulfur fungicide treatments until the blight is eradicated, or remove and dispose of infected plants. Compost spoiled material instead.
