The spring onion (Allium fistulosum), also known as the spring onion, winter onion, winter onion, Schlotten onion or stalk bulb, belongs to the Amaryllis family (Amaryllidaceae). In the literature, the term Winterheckenzwiebel is usually used, colloquially meanwhile, spring onion has largely prevailed - even if the spring onions, which you can buy in our supermarket, is not always Allium fistulosum. Especially in early spring occasionally other young onions (Allium cepa) are offered as spring onions. The name Winterheckenzwiebel probably comes from the fact that the plant is cultivated perennial and in the bed in mild regions even in winter forms a low green hedge.
The spring onion is native to Asia - in China, Japan and Korea, the finely cut tube leaves refine almost every dish. In the kitchen, spring onion uses the foliage called "sludge", which consists of thin, dark green tubes. While the spring onion is cultivated in Asia on an annual basis, it is usually cultivated perennial with us.
Appearance and growth
In July, the spring onion forms white flower balls
The spring onion is a perennial plant that forms clumps and reaches stature heights between 30 and 80 centimeters. Their onions are not comparable to conventional onions, unlike them they are not clearly distinguished from the foliage. Instead, spring onions in the lower part have a small, white thickening. The aromatic foliage is used in the kitchen, which can be harvested almost all year round: dark green, hollow tube leaves. In July large globules, which consist of numerous small white single flowers, appear on thick stems, also hollow in the middle.
Location and ground
Leek or spring onions thrive best in sunny and sheltered locations. The soil should be deep, loose and humus.
Crop rotation and mixed culture
Salad, cucumbers and carrots are good partners for spring onions. On the other hand, bean types are not suitable for the mixed culture with spring onions.
The horstbildende winter onion can be grown on the same site for several years
To optimally prepare the bed, rake in three to five liters of sieved Reifkom-post per meter. From March to May, you can sow the seeds of the winter bulbous on a broad base - about one centimeter deep. The optimal row spacing is 20 centimeters. After emergence, separate the seedlings to a distance of five to eight centimeters. Follow-up tickets are possible until mid-August. So you can gradually sow again and again, so you always have fresh spring onions at hand.
Winter tail bulbs are relatively easy to care for and the care is similar to that of the chives. In addition to watering, you should regularly provide the spring onions with organic fertilizer. So that the clumps do not grow too densely and thus lose their growth power, you should excavate the perennial plants for rejuvenation every two to four years, divide them and place them in a new place in the ground (see multiplication).
Harvest and recovery
Spring onions give cottage cheese, salads and Co. a fresh touch
The leaves of the spring onion can be harvested not only in spring, but all year round. You can cut the leaves of the perennial winter onion like chives, these then drift again. Or you pull the whole plant out of the bed. As the leaves of the leek onion wither quickly, it is best to harvest as needed. After you cut the tube sheets with a sharp knife, you can sprinkle them over the dishes just before serving to refine soups, salads or quark - so you keep their aromatic, leek-like taste. In addition, the leaves of spring onion give boiled or steamed dishes a special touch.
'Elody' is cold-proof, with snow-white, mil-onions. It is suitable for sowing in spring as well as for a late summer sowing with hibernation. 'Baja Verde' does not produce onions and grows very quickly. The spicy, green-white stems taste in Asian dishes. 'Pal' grows fast and develops white, aromatic branches with fresh green foliage. There are also varieties with white and red stem: 'Long White Milda' and 'White Lisbon' have a white, 'Red Beard' and 'Toga' a red.
One can multiply spring onions either by sowing or by division of the clumps.You can even collect the black seeds, which are easy in the summer, and let it dry. They are germinable for up to two years. Or you share the clumps in summer. To do so, dig out the root ball of an older plant and carefully split two to three sections with a spade. Refill this at a new location.
Diseases and pests
The winter-tailed onion is very robust and disease-resistant. Occasionally occur leek moths, thrips and downy mildew.
