Scallions are ready to pick as soon as they reach about six to eight inches tall, which usually happens about 60 to 90 days after sowing seeds.
That’s the short answer, but knowing exactly when scallions are ready to pick can depend on a few different factors like the variety you’re growing and how you plan to use them.
If you’re asking when are scallions ready to pick because you see skinny green tops waving in the breeze, you might be closer to harvest time than you think.
The beauty of scallions is that they’re incredibly forgiving, so you don’t need to stress about a perfect harvest window.
In this post, we’ll walk through the signs that tell you when are scallions ready to pick, the best techniques for pulling them, and a few storage tips so they stay crisp and fresh.
Let’s dig into the details so you never wonder about scallion readiness again.
When Are Scallions Ready to Pick? Key Signs to Watch
1. Height Matters More Than Age
When you’re checking when are scallions ready to pick, height is your most reliable indicator.
Scallions should be at least six inches tall, but they’re even better when they reach ten to twelve inches in height.
If they’re shorter than six inches, the white bulb portion underground might not have developed enough to give you that satisfying crunch.
So grab a ruler or just eyeball it, but the taller the green stalks, the more mature the scallion is.
2. Look for a Pencil-Thick Shaft
Another visual cue for scallion readiness is the thickness of the stalk at the base.
Scallions are ready to pick when the shaft right above the soil looks about as wide as a pencil.
If the base is still super thin like a blade of grass, give them another week or two to bulk up.
But if you’re asking when are scallions ready to pick because the bases look plump, that’s your green light to harvest.
3. The Soil Level Tells a Story
You can also check scallion readiness by brushing away a little bit of soil from the base.
Scallions are ready to pick when you see a decent amount of white flesh under the green leaves.
That white portion is the prized part for salads and stir-fries, and it only forms with enough growing time.
If you only see green right down into the dirt, they’re still building their bulbs and not quite ready.
4. Taste Testing Is Always Allowed
Sometimes the best way to determine when scallions are ready to pick is by simply tasting one.
Pull up a single scallion, give the white part a nibble, and check for a mild onion flavor with a bit of sweetness.
If the taste is sharp and overly strong, they might be past their peak and starting to form a true onion bulb.
That’s fine, but scallions are ready to pick when they still have that delicate, fresh bite.
How Early Can You Start Picking Scallions?
1. Baby Scallions Are a Thing
Technically, scallions are ready to pick at the baby stage once they’re just a few inches tall.
You can thin your rows by pulling tiny scallions when they are about four inches tall.
These babies are tender and perfect for garnishing, but you’ll get a smaller yield per plant.
So if you’re wondering when are scallions ready to pick for a full harvest, wait for that six-inch mark or beyond.
2. Warm Weather Speeds Things Up
The season also affects when scallions are ready to pick because warmer temperatures accelerate growth.
If you planted in early spring, expect scallions to be ready in about 75 to 90 days.
But if you planted in late spring or summer, scallions can be ready to pick in as little as 50 days.
Keep an eye on the thermometer because heat pushes them along faster than cool, cloudy weather does.
3. Don’t Wait Too Long
While scallions are forgiving, they don’t stay in the perfect harvest zone forever.
Once the base starts swelling into a round bulb, the scallion is becoming a spring onion or even a bulbing onion.
If you miss that window, scallions can turn woody and lose their crisp texture, so harvest before that happens.
That means knowing when scallions are ready to pick is about timing your pulling just before the bulb expansion begins.
Best Practices for Harvesting Scallions
1. Loosen the Soil First
To check if scallions are ready to pick, you’ll need to pull them without snapping the stems.
Use a hand fork or a trowel to gently loosen the soil around the base of each scallion.
Then grasp the scallion near the bottom, close to the white part, and tug upward with a twisting motion.
This technique prevents the roots from breaking off and keeps the entire scallion intact.
2. Harvest as You Need Them
Scallions don’t all need to come out at once, so treat them like a cut-and-come-again crop.
You can pull individual scallions whenever you need them once they’ve hit that six-inch height.
This staggered approach means you’ll always have fresh scallions ready to pick for weeks.
Just don’t forget that each pulled scallion is a finished plant, so plant new seeds every few weeks for a continuous supply.
3. Use a Sharp Knife or Scissors
Another method to figure out when scallions are ready to pick is to try the cut-and-regrow trick.
Instead of pulling the whole plant, you can snip off the green tops about two inches above the soil.
The scallion will regrow in a few weeks, giving you another harvest from the same root system.
This works best if you’re only using the green leaves and don’t need the white bulb portion.
Storing Scallions So They Stay Fresh
1. Rinse and Wrap in a Damp Towel
After you’ve confirmed that your scallions are ready to pick, the storage process begins right away.
Rinse off loose soil, shake dry, and wrap the whole bunch in a damp paper towel.
Place them in a plastic bag or an airtight container in the fridge’s crisper drawer.
This method keeps scallions fresh for up to a week or sometimes even longer.
2. Standing Them in Water Works Too
For an even simpler approach, treat scallions like cut flowers.
Stand the white ends in a jar with about an inch of water and cover the greens loosely with a plastic bag.
Change the water every couple of days, and your scallions will stay crunchy and vibrant for ten days or more.
3. Freeze Them for Longer Storage
If you’ve harvested a big batch and can’t use them quickly, chop the scallions into small pieces.
Spread them on a baking sheet and freeze them solid before transferring to a freezer bag.
Frozen scallions won’t have the same raw crunch, but they’re perfect for soups, stews, and cooked dishes.
So, When Are Scallions Ready to Pick?
Scallions are ready to pick when they hit six to eight inches in height and have a base as thick as a pencil.
That’s the golden rule regardless of whether you planted seeds or started with sets.
You can always harvest baby scallions earlier, but the classic scallion is ready to pick after about 60 to 90 days of growth.
Keep an eye on the base, taste test one if you’re unsure, and don’t hesitate to pull them early for a milder flavor.
So the next time you’re looking at your garden bed and wondering when are scallions ready to pick, just measure that height.
Once they’re at least six inches tall, grab your trowel and enjoy the freshest scallions you’ve ever tasted.
