Similar Species
Distinguishing bunching onions from other allium varieties can be a bit tricky. Although pretty much any type of onion will produce edible greens, bunching onions have their unique qualities.
Cultivation and History
Contrary to popular belief, bunching onions, often referred to as Welsh onions, did not originate in Wales. In fact, they have their roots in China and have been used by humans for over two millennia. These onions made their way to Japan by 500 AD and gradually spread across Asia and Europe before arriving in North America.
Apart from their culinary uses, bunching onions also play a significant role in Chinese medicine. They have been used to improve metabolism, prevent cardiovascular disorders, and fight colds and upper respiratory infections. Additionally, a poultice made from scallions is believed to have healing properties for treating infections and sores.
From Seedlings/Transplanting
To grow bunching onions from seed, start them indoors about five to six weeks before the last frost date. Once the plants are a few inches tall and all danger of frost has passed, transplant them to the garden. Before planting, ensure the soil is moist, and consider dipping the bottom of the roots in water or liquid fertilizer.
Division
Once established, bunching onion plants can be easily divided to spread throughout your garden or share with friends and neighbors. Spring is the ideal time for division. Simply dig up a clump, carefully split the root ends into several sections, and replant.
How to Grow
Bunching onions are known for their resilience. They can tolerate almost any soil conditions and even withstand drought. However, providing nutrient-rich soil, full sun, and regular watering will enhance the quality of your crop. Liquid feed, such as comfrey tea or fish fertilizer, can also boost growth.
To make homemade comfrey tea fertilizer, cut a bunch of comfrey leaves and place them in a bucket of water for a few days. Strain the mixture, and you have a nutrient-rich “tea” to feed your plants.
Keeping the area around your onions free from weeds is crucial. Mulching around the plants will not only suppress weed growth but also help retain moisture in the soil.
Managing Pests and Disease
Bunching onions are generally not attractive to pests. However, some pests, such as allium leaf miners and thrips, can occasionally cause problems. Implementing preventive measures, like integrated pest management and using row covers, can help protect your crop.
Several diseases, including white rot, downy mildew, and botrytis leaf blight, can affect bunching onions. Practicing crop rotation, avoiding infected starts or seeds, and planting in well-draining soil can help minimize the risk of disease.
Harvesting
You can harvest bunching onions in two ways: pulling up entire plants like green onions or snipping off leaves as needed, similar to chives. Snipping off leaves allows for regrowth, allowing you to enjoy the harvest throughout the growing season. Harvesting can begin when the plants reach four to six inches in height.
Preserving
Bunching onions can be stored in the refrigerator’s crisper drawer for up to 10 days. They can also be easily frozen or dried for longer preservation. To freeze, wash the greens, chop them into rings, and pack them into freezer containers. Drying the greens is an excellent method for long-term storage. Wash and chop the greens, air dry them, and either use a dehydrator or the oven’s lowest heat setting until they are moisture-free.
Recipes and Cooking Ideas
Bunching onions add a delightful crunch and spice to various dishes. They can be used in dips, soups, salads, sandwiches, broths, stir-fries, and as a garnish. Get creative with these sharp green leaves and explore the many ways to prepare and enjoy them in your meals.
Growing and harvesting bunching onions can be a rewarding experience. With their easy cultivation, resilience, and rich flavors, these versatile plants are a valuable addition to any garden. So why not give them a try?
