Description
The 'Premier' Onion is a variety to be harvested in spring and summer, with rapid growth. It is cultivated for its small white bulbs, with firm and sweet flesh. It is an ideal onion for caramelising, and is used raw or cooked in many dishes. Sowing period is from February to April and from August to September for a harvest 3 to 6 months later.
There are around 900 species of onions, which are commonly categorised by colour: white, yellow, red, pink, or green. The onion is native to Central Asia, where it has been consumed for over 6000 years. Its presence is also noted in the tombs of pharaohs as a provision for the afterlife. Its therapeutic and gustatory virtues were already recognised. The Romans later introduced the onion to Western Europe. It is worth noting that it was Christopher Columbus who introduced it to the Americas during his second voyage.
This vegetable, rich in sulphur compounds, causes tears as soon as it is cut. It is these same compounds that are responsible for its hypoglycemic properties. Among other properties, the onion is known to reduce cholesterol levels in the blood and lower blood pressure. Rich in vitamins A, B, C, and minerals, it is often more digestible when cooked and takes on a sweeter flavour.
Harvesting: to keep your onions "in storage" for as long as possible, it is necessary to harvest them under good conditions. First, make sure you have two to three days of good weather ahead. Onions are harvested when the stems are completely dried and flattened on the ground. Gently pull them out and let them dry for two to three days on the ground in the sun. After that, remove the excess dry soil by lightly rubbing them. Spring sowings are harvested in July-August to be consumed in autumn and winter. Autumn sowings are harvested in March to be consumed in spring and summer.
Storage: if the condition of the stems allows, you can make a braid and then hang the bunches. Otherwise, place your onions on racks in a dark, cool, dry, and well-ventilated place to prevent them from rotting. Check beforehand that they have not been bruised to avoid rot that could contaminate your entire harvest. If the storage place is too warm, the onions will tend to sprout. They can be stored for 5 to 7 months under good conditions. Of course, you can also consume your onions as you need them. They are actually best when fresh. In this case, the fresh leaves are also edible.
The Gardener's Tip: associate your onions with your carrots. Onions repel the carrot fly, while carrots moderate attacks from the onion fly. Onions like the company of beets, strawberries, and lettuces. But they hinder the growth of broad beans, peas, and beans.
Untreated or "NT" seeds come from plants cultivated conventionally (often with the use of pesticides), but they undergo no treatment after harvest. These seeds are allowed in organic market gardening when organic seeds are out of stock.

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).
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.
