Description
The 'Jaune de Mulhouse', Auxonne type onion is grown over two years. This variety has the particularity of producing aerial bulblets. Sowing is done from May to June and the bulblets are harvested from August to September. They will be replanted in March of the following year to become beautiful, fairly small and round onions with a lovely coppery yellow skin. They can then be stored very well.
The onion is an herbaceous plant that produces a single bulb topped with hollow, cylindrical stems. It belongs to the Liliaceae family, like garlic, shallots, and chives. The onion is primarily cultivated for its bulb and sometimes for its stems, which are consumed in the same way as chives.
There are three groups of onions, distinguished by the colour of their bulbs:
- the white onions, which are early varieties, consumed while young in stir-friess or pickled in vinegar,
- the yellow onions, which are storage varieties, often consumed cooked (in soups, savoury pastries, or as preserves accompanying cheese or charcuterie),
- the red onions, which are usually consumed raw in salads or cooked.
There are also less common pink onions, such as the 'Roscoff' pink onion.
Rich in vitamins A, B, C, and minerals, onions are often more digestible when cooked and develop a sweeter flavour. To avoid crying while cutting an onion, you can sharpen your knife, peel it under running water, in a basin of water, or wear swimming goggles!
Historically, onions originate from Central Asia, where they have been consumed for over 6000 years. They were also found in the tombs of the pharaohs as provisions where their therapeutic and gustatory virtues were already recognised. The Romans later introduced onions throughout Western Europe. It is worth mentioning that Christopher Columbus introduced onions to the Americas during his second voyage.
Harvesting: White onions should be harvested in spring when the foliage is still green. Coloured onions (yellow, pink and red) should be harvested in summer when the stems are completely dried and laid flat on the ground. Gently pull them out and let them dry for two to three days directly on the ground in the sun. Remove any excess dried soil by lightly rubbing them.
Storage: Onions can be stored for several months under good conditions. If the condition of the stems allows, you can braid them and hang the resulting bunches. Otherwise, cut off the leaves and store the onions in a dark, cool, dry, and well-ventilated place. Check beforehand that they have not been bruised to prevent rotting, which could contaminate the entire harvest.
Gardening tip: Alternate rows of onions and carrots to keep carrot fly and onion fly away. Additionally, onions thrive when planted alongside beets, strawberries, and lettuces.

Planting and care
Soil preparation: Onions thrive and grow in all types of soils, preferably light and well-drained. The soil should not have received manure for at least a year. Onions fear excess nitrogen, so avoid planting them after green manure or vegetables from the Fabaceae family (beans, peas, fava beans). Rotate approximately every 5 years before growing onions again.
Spring sowing: Coloured onions (yellow, pink and red) and some early varieties of white onions are sown from February to April, directly in place (or in autumn if the climate is mild). Mark the sowing rows by stretching a string, spacing the rows 20 cm (8in) apart. Dig a furrow 2 cm (1in) deep and sow thinly. Close the furrow by lightly tamping with a rake. Moisten the soil immediately after. Germination takes about 18 days. When the plants reach 5 cm (2in) (about 2 months after sowing), thin out, leaving one plant every 10 cm (4in). Harvesting can then be done throughout the summer.
Autumn sowing: White onions are sown at the end of summer (August-September) in crates or trays. They will be transplanted into the ground either a month later in mild climates or at the end of winter around February. Allow 20 cm (8in) between rows and 10 cm (4in) within the row. White onions are then harvested in spring.
Regular tasks: Regularly hoe, especially at the beginning. No mulching to prevent rotting. Onions dislike moisture, so watering should be kept to a minimum, mainly during sowing and transplanting.
It is also possible to produce bulblets oneself: sow in March, then keep one plant every 2 cm (1in), harvest bulblets with a diameter of less than 2 cm (1in) in July, store them dry during winter, and plant them in the following spring.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
