Welsh White Onions, scientifically known as Allium fistulosum, are a perennial species of onions commonly referred to as bunching onions, spring onions, or scallions. Unlike the common bulb onion (Allium cepa), Welsh onions do not form a significant bulb. Instead, they produce long, cylindrical, hollow green stalks, which are primarily used in cooking. The flavor is similar to that of onions but milder, making them ideal for salads, garnishes, and various culinary dishes.

Used fresh in salads, as a garnish, or in cooked dishes. The entire plant, including both the white and green parts, is edible. The plants can also be grown for ornamental purposes due to their attractive green foliage and occasional white or lavender flowers.

Characteristics:  Welsh White Onions grow in clumps, with tall, hollow green stems that can reach up to 30-50 cm (12-20 inches) in height. The lower part of the stem near the roots is white, which gradually transitions to green as it extends upward. Their flavor is milder than regular onions, with a slightly sweet and crisp texture. Unlike most onions, Welsh onions are perennial and can be left in the ground year after year. They are very hardy and can survive cold winters.

GROWING TIPS

Soil Preparation & Planting:  Welsh onions thrive in well-drained, fertile soil rich in organic matter. They prefer a slightly acidic to neutral pH (6.0-7.0). You can start Welsh onions from seeds, sets, or transplants. If planting from seeds, sow them directly into the garden in early spring or late summer for a fall crop. They can also be started indoors a few weeks before the last frost. Plant seeds or sets about 1 inch deep, spaced 4-6 inches apart in rows that are 12-18 inches apart.

Watering & Fertilization: Keep the soil consistently moist, especially during dry spells. However, avoid waterlogging, as it can cause the roots to rot. Mulching around the plants can help retain moisture and suppress weeds. Use a balanced fertilizer (like 10-10-10) at the time of planting. During the growing season, you can side-dress with compost or a nitrogen-rich fertilizer to encourage leafy growth.

Harvesting: You can start harvesting Welsh onions when the stalks are about pencil-thick. If growing as a perennial, harvest sparingly to allow the plants to regenerate. For continual harvests, divide clumps every few years to maintain vigor.

Pests and Diseases: Welsh onions are relatively resistant to pests and diseases, though they can occasionally suffer from onion maggots or thrips. Rotating crops and practicing good garden hygiene can help mitigate these issues.

Winter Care:  In colder climates, mulch heavily over the plants in late fall to protect them from freezing temperatures. Welsh onions can overwinter and resume growth in spring.
