How to successfully grow chives

Closely related to chives, onions and shallots, chives are grown for their aromatic leaves and bulb . Just two or three clumps of this easy-to-grow plant are enough to provide for a family. With a milder flavor than garlic and onions, chives are very popular in Asian cuisine . Undemanding and quite hardy, they thrive in pots or in the ground in vegetable and herb gardens, but also in borders and ornamental beds . They form beautiful, dense clumps and the flowers are lovely. If the winter is not too harsh, they keep their leaves and can therefore be harvested throughout the season.

Growing chives

The history of chives

The ancestor of the spring onion is Allium altaicum, a wild lily domesticated in China and growing wild in Mongolia. The particularity of many lily plants is that they have a very similar morphology, even between two different species. It was therefore quite difficult until the first half of the Middle Ages to know exactly which of the two was cultivated: spring onion, chives, or even garlic and wild leeks. We do know, however, that it was one of the plants recommended for cultivation in royal domains by Charlemagne in the capitulary De Villis*. Today, it is found in dishes all over the world, although it is more common in Asian cuisine.

Etymology

The term "chives" comes from the Occitan "cibola", itself from the Latin "caepulla", a diminutive of "caepa" which means "onion".

Taste

The taste of chives is reminiscent of onion, but much finer, more delicate, with a slight hint of garlic.

Nutritional values

Chives are said to have antiseptic and digestive properties. Like all Alliaceae, chives are rich in antioxidant compounds (vitamin C, flavonoids), mineral salts, and B vitamins.

Anecdotes

As the leaves are very rich in vitamin C, pilgrims on the Way of St. James used them to combat scurvy (a gum infection caused by vitamin C deficiency, which can lead to death).

Main subspecies and varieties

Evergreen nebuca chives, red toga chives, winter nest chives.

    • Between rows: 20 cm between rows.

Cultivation techniques

Crop rotation

The chives can stay in place for 3 or even 4 years.

Companion plants

Chives particularly appreciate the presence of carrots. Indeed, chives enhance the flavor and promote the growth of carrots, which will repel the leek fly to which chives are sensitive. In addition, chives limit apple scab or black spot on roses. They also appreciate the presence of beets, Roman chamomile, cucumbers, and strawberries. On the other hand, chives do not like the presence of Fabaceae. Indeed, like all Alliaceae, they do not appreciate the overdose of nitrogen in the soil that Fabaceae provide.

Technical gestures

It is advisable to cut the flowers as soon as they appear to avoid tiring the chive plants. In addition, remove the dry stems from each plant in March of each year.

Conservation and storage

  • Directions: You can freeze or dry chives, but they will lose their flavor and are always better fresh.
  • Duration: Frozen or dried chives can be stored for several months, but fresh, they will only keep for 2 or 3 days.

Uses of chives

  • Culinary : Everything about the chive is edible: the pseudobulbs, the stems, and the flowers. The aroma is reminiscent of onions, but much finer and more delicate, with a slight hint of garlic. The white part of the chive is used like onions. The flower petals enhance salads. The green part of the stems is used raw to flavor raw vegetables, salads, sauces, or white meat.

Tips and tricks

Chives are a honey plant, so they will attract pollinators to the garden, including bees, which can be very beneficial to other vegetable species that depend on them.

Diseases and pests of chives

Diseases

The pests

Chives do not seem to fear any disease.

Chives are susceptible to onion flies, moths, and leek leaf miners. To prevent these infestations, chives can be planted near carrots, as carrots repel leek pests. Using insect netting is also a very effective way to protect chives from these pests.
