ㅇ The leaves of leeks appear regularly in sequence from the lower leaf to the upper leaf every 5 to 8 days, and the growth continues for 15 to 20 days after leaves, and in the meantime, it overtakes the first leaf and reaches the maximum leaf length.
ㅇ The lifespan of a single leaf varies depending on external conditions such as leaf age, nutrition, and temperature, but the survival period is usually 30 to 40 days after leaves.
■ Sowing and Planting Seedlings:
ㅇ Germination Temperature: 59-68˚F
ㅇ Seed Depth: ¼ ”
ㅇ Seed Spacing: 2 ”
ㅇ Plant Spacing: 4 – 6 ”
ㅇ Row Distance: 14 – 20 ”
ㅇ Maturity Days: 90 Days
■ How to Grow:
1. Sowing
– If green onion seeds are sown directly in the field in spring, they will sprout after a month.
– It can be sown in a tray raised as a seedling and planted in the field.
– For spring and summer planting, place the seeds just below soil level and apply a light compost cover.
– When planting in the fall, plant the seeds 2-4 inches deep and a few inches of mulch.
– Water once every 3-4 days.
* More Information on Welsch Onion Planting Times:
ㅇ Fall Planting: The welsh onions overwinter in the garden and can be harvested from late winter to late spring, at which point bulbs or bolts form. Allium Fistulosum is one of the cold-tolerant onions that can withstand temperatures below 0°F.
ㅇ Spring Planting: They divide and reproduce at the base the following winter. Each plant will be 4, 5, or more plants.
ㅇ Mid-summer Planting: It will be ready to harvest from late winter to late spring.
ㅇ Indoor Planting:
– Sow seeds indoors at least 4 weeks before the last frost in spring. You can start harvesting indoors after the last average frost date or transplant seedlings into your garden.
– Pot Planting: Grow seeds in pots that are at least 12 inches wide and 8 inches deep. Scatter the seeds and then gradually thin them out at least about 2 inches apart.
ㅇ Outdoor Planting:
– Sow Welsh onion seeds outdoors in the early spring or fall as soon as the soil can work.
– In cold winter regions, Welsh onions are planted in late autumn and winter. Welsh onions can be eaten in early spring.
– In mild winter areas, place the plant just below soil level and apply light mulch.
– Sow the seeds every 2 to 3 weeks to ensure continued harvest through the season.
– Sow the seeds in late summer or fall to allow seedlings to settle before dormancy. You can protect the plant during the winter with mulch or grow it under the protection of a plastic tunnel.
2. Watering:
– Plants are often lightly watered at the soil level.
– Avoid wetting the leaves, which can cause disease.
3. Feeding: Feed Welsh onions with a balanced organic fertilizer every 3-4 weeks.
4. Mulching:
– In late spring and summer, mulch around plants with old compost or grass clippings to conserve moisture and add nitrogen to the soil.
– Mulch the plants with straw in the fall to protect them from the cold. This is especially important in Zone 5 and below.
5. Weeding: Weeds growing near plants are removed by hand pulling or gentle cultivating to avoid damaging the roots.
■ Harvest:
ㅇ Harvest when green onions grow in the middle or when they are about 1/2 inch thick and at least 6 inches tall.
ㅇ Do not pull on the plant as the stem can break easily. Use a trowel to uproot the plant.
ㅇ Before the frost falls and it gets cold, pull out all the green onions and store them.
ㅇ If you plant some of the green onions harvested indoors in a pot or a Styrofoam box with soil, you can eat fresh green onions all winter long.
ㅇ The leftover green onion can be planted in the field in the spring of the following year.
ㅇ To increase the number of shoots or start a new cluster, detach the cluster or single shoot on a new branch and replant. they will multiply.
■ Nutritional Value :
❍ The leaf part of green onion is rich in beta-carotene, which effectively removes free radicals, one of the main causes of aging. It is also rich in calcium, which helps to maintain joint health.
❍ The white stem of green onion has a high content of vitamin C, which contains five times more vitamins than apples.
❍ Allicin, which is contained in large amounts in a green onion root, has the effect of improving blood circulation and enhancing immunity, and also improves and relieves insomnia by stabilizing the nerves. In addition, allicin helps the absorption of vitamin B1, so it is good to take it with food with a lot of vitamin B1 content, and the starch and sugar in the food are converted into calories, thereby relieving fatigue.
❍ In addition, the roots are rich in polyphenols that are activated without destroying nutrients even when heated.

Thank you! Thank you!
Half-Korean Diaspora here. I have faded memories of my mom and aunties together making kimchi.
When my father remarried, through my stepmom, I grew up mostly learning how to make flour tortillas, salsa, etc. It’s only lately I’ve become interested in learning more about my mother’s culture (with a little encouragement from my husband).
I am very grateful to have found your website.
I appreciate that along with recipes you provide non- gmo seeds for plants I can’t find even at any specialty Asian market in my area. And I have purchased seeds from other online sites and found most of them are hybrids. This is unfortunate, because there is no guarantee that the seeds from those plants will produce the same crop next year.
I can’t say enough how grateful I am to have finally found your website, and the seeds in your Etsy shop. It is honest sustainability through the old proverb “teach the man to fish” especially these challenging times.
Lately, with the rising cost of food (particularly specialty foods) as well as wanting to incorporate more into creating Korean meals for my family, I am also looking for lessons in Korean food storage and meal planning. I understand it is dependent on the seasons (as with any healthy meal), but it sometimes it gets confusing (the part where I am trying to incorporate more daily Korean meals). I guess I am so use to cooking Western, and Mexican meals that cooking Korean meals is a new experience for me so I end up mostly cooking Korean for special gatherings.
I would like to change that.
It would be easier for my simple brain if there was a book that simplifies the flow of produce seasons, the harvest, food storage and the corresponding recipe meals.
Hopefully you understand what I mean…
Example: A few seeds to start. Each with growing instructions to harvest/ curing/ storing. Included few simple corresponding starter recipes for the plants fresh from harvest for that season. Along with basic corresponding recipe meals from the food storage.
Maybe it’s more complicated than it sounds, but it might make a very interesting gift set.
Thank you for the seeds for Korean produce I simply can’t find anywhere in my area, and Thank you for including the recipes that go with them!
Thank you! Thank you!
Dear Antonia,
Thank you so much for taking the time to share your beautiful journey and family story with me. I apologize from the bottom of my heart for the delayed reply—I only just saw your sweet comment from June, and I feel so terrible for taking this long to get back to you!
First of all, as a fellow Korean, it brings me so much warmth and joy to connect with you. Hearing about your memories of your mother and aunties making kimchi truly touched my heart.
What gave me complete chills while reading your message is that I am currently working on the exact project you described! I am in the final testing stages of a new recipe & seed card set. Each seed packet will come with detailed growing/planting info cards, as well as 4 easy-to-follow Korean recipes tailored to that specific vegetable—from fresh harvest dishes to daily home-cooked meals!
Knowing that someone like you—who genuinely cares about authentic Korean food, health, and sustainable home gardening—is looking for something like this means the absolute world to me. It reassures me that this project is truly needed and meaningful.
Thank you again for discovering my Etsy shop and website, and for sharing your thoughts so openly. I am working hard to finalize the recipe card sets, and I can’t wait to share the good news with you very soon when they officially launch!
Warmest regards,
Aeri
