How do you harvest scallions

Harvest scallions when the stalks are at least 6 inches tall and about 1/2 inch thick, typically 60 to 90 days after planting, depending on variety. You can pull the whole plant for a single harvest, or cut the leaves above the white base to encourage regrowth for multiple harvests. Here is the straightforward method that works in most home gardens.

When to harvest scallions

Scallions, also called green onions or bunching onions, are ready earlier than bulb onions. Start checking at 60 days for spring-planted scallions, or when the plant has at least four leaves and the white part is 1 to 2 inches long. The ideal time is just before the plant starts to form a bulb; if you see a swelling at the base, harvest soon or the texture becomes fibrous.

For fall-planted scallions (zones 7 and warmer), you can harvest through winter and into early spring. In colder zones, plant in early spring as soon as the soil can be worked, and harvest from late spring through summer.

How to harvest: two methods

Method 1: Pull the whole plant

Use a garden fork or trowel to loosen the soil around the roots, then grasp the base of the plant and pull straight up. Shake off excess soil. This method gives you a full scallion with the root attached, which stores longer. It is best when you want a large batch for cooking or preserving.

Method 2: Cut and come again

Use sharp scissors or a knife to cut the leaves 1 to 2 inches above the soil line, leaving the white base and roots intact. The plant will regrow in about 3 weeks, giving you up to three or four harvests per planting. This method is great for a continuous supply but yields less per harvest.

For either method, harvest in the morning when the plants are crisp and hydrated. Avoid harvesting after heavy rain, as the leaves may be waterlogged and prone to bruising.

Tools and costs

You need minimal tools: a garden fork (around $15 to $25), a trowel ($10 to $15), and sharp scissors or a knife. If you are harvesting many plants, a hori-hori knife ($20 to $35) works well for both digging and cutting. No specialized equipment is required.

Storing fresh scallions

Fresh scallions keep in the refrigerator for 1 to 2 weeks. Wrap the roots in a damp paper towel and place in a plastic bag, or stand them upright in a glass with an inch of water and cover loosely with a plastic bag. Change the water every few days. Do not wash until ready to use, as moisture speeds spoilage.

For longer storage, chop and freeze scallions in a single layer on a baking sheet, then transfer to a freezer bag. Frozen scallions lose their crispness but are fine for cooking. You can also dry them in a dehydrator at 125°F for 4 to 6 hours, then store in an airtight jar.

Varieties that perform well

Choose varieties suited to your zone and harvest method. For cut-and-come-again, look for perennial bunching types. For single harvest, any scallion variety works.

Variety	Type	Days to maturity	Best for
‘Evergreen White’	Bunching	60-70	Cut-and-come-again, cold hardy
‘Tokyo Long White’	Bunching	65-75	Long white shanks, mild flavor
‘Red Beard’	Bunching	70-80	Red stems, decorative, good for fall
‘White Lisbon’	Bunching	60-70	Single harvest, classic flavor
‘Nabechan’	Bunching	65-75	Heat tolerant, slow to bolt

For zones 5 and colder, ‘Evergreen White’ overwinters well with mulch. In zones 8 and warmer, ‘Red Beard’ and ‘Nabechan’ handle heat better.

Common mistakes and fixes

• Harvesting too early: If the stalks are thinner than a pencil, wait a week or two. Thin scallions are edible but less productive.
• Harvesting too late: Once the bulb starts to form, the texture becomes woody. Harvest promptly or use as small bulb onions.
• Cutting too low: If you cut below the white base, the plant may not regrow. Leave at least 1 inch of the white part.
• Not loosening soil: Pulling without loosening can break the roots and leave the plant behind. Always loosen first.

FAQ

Can I harvest scallions multiple times? Yes, using the cut-and-come-again method. Cut leaves 1 to 2 inches above the soil, and the plant will regrow in about 3 weeks. You can get 3 to 4 harvests per planting, though flavor may be slightly milder after the first cut.

What is the best time of day to harvest? Morning, after the dew has dried but before the heat of the day. Plants are fully hydrated and crisp. Avoid harvesting in the afternoon when leaves may be wilted.

How do I know if scallions are ready? Stalks should be at least 6 inches tall and about 1/2 inch thick. The white part should be 1 to 2 inches long. If you see a bulb starting to form, harvest immediately.

Can I regrow scallions from kitchen scraps? Yes, place the white root ends in a glass of water and change it daily. You will get a few inches of regrowth in about a week, but the flavor is weaker than garden-grown. For best results, plant the scraps in soil after roots form.

The bottom line

Harvest scallions when they are young and tender, about 60 to 90 days after planting. Pull the whole plant for a single harvest, or cut leaves for multiple harvests. Use a fork to loosen soil, harvest in the morning, and store in the fridge with damp paper towels. With the right timing and method, you can enjoy fresh scallions from spring through fall, and even winter in mild climates.
