Description
The 'Red Karmen' onion is a productive variety that produces flat, globe-shaped red onions. This variety is well suited for winter storage. Plant the bulblets from February to April (or in autumn for mild climates) and harvest in July and August.
Onions are herbaceous plants that produce a single bulb topped with hollow, cylindrical stems. They belong to the Liliaceae family, along with garlic, shallots, and chives. Onions are primarily grown for their bulbs and sometimes for their stems, which can be consumed like chives.
There are three groups of onions, distinguished by the colour of their bulbs:
- White onions, which are early varieties and can be consumed fresh or pickled,
- Yellow onions, which are storage varieties and are often cooked (in soups, pissaladières, or as accompaniments to cheese and charcuterie),
- Red onions, which are typically consumed raw in salads.
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 peel it under running water, in a bowl of water, or wear swimming goggles!
Historically, onions originate from Central Asia, where they have been consumed for over 6000 years. Their presence has also been found in the tombs of pharaohs as a food supply. Their therapeutic and culinary properties were already recognised. The Romans later introduced onions to Western Europe. It is worth noting that Christopher Columbus introduced onions to the Americas during his second voyage.
Harvest: White onions should be harvested in spring when the foliage is still green. Coloured bulb onions (yellow and red) should be harvested in summer when the stems are completely dried and bent to the ground. Gently uproot them and let them dry for two to three days on the ground in direct sunlight. 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 bundles. 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 and onion flies away. Additionally, onions thrive when planted alongside beets, strawberries, and lettuces.

Planting and care
Onions thrive and grow in all types of soil, preferably light and well-drained. The soil should not have received any manure for at least one year. Choose a sunny spot. Onions are sensitive to excess moisture, which can cause the bulbs to rot. If your soil is very wet, add some sand to it. Planting on mounds will help facilitate water drainage and slightly increase the soil temperature.
Bulblets are very young onions that are planted in spring, from February to April. In regions with mild winters, they can be planted in autumn, in October-November. Planting bulblets requires less weeding than sowing while ensuring a good harvest.
Loosen the soil. Space the rows 25 cm (10in) apart. Build up the soil along the entire row to form a mound 10 to 15 cm (4 to 6in) high. Flatten the top. Plant the onion bulblets every 15 cm (6in), with the pointed end facing up, by gently pressing them down. Cover with a little fine soil, with the tip just above the ground. Watering is not necessary.
Regularly hoe, especially in the beginning. Mulching is not necessary.
Onions dislike excessive 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.

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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
