Description

The 'Keravel' pink onion, a variety approved by the Roscoff onion association, is of excellent taste quality. It produces onions with a pink skin and flesh. Plant the bulblets from February to April (or in autumn for mild climates) and harvest the onions in July and August.

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 mainly cultivated for its bulb and sometimes for its stems, which are consumed like chives.

There are three groups of onions, distinguished by the colour of the bulb:

- white onions, early varieties, consumed in vegetable gardens for example or pickled in vinegar

- yellow onions, for storage, often consumed cooked (in soups, pissaladières, or as accompaniments to cheese or charcuterie),

- red onions, usually consumed raw in salads.

There are also pink onions, less common, like the ''Keravel' 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 basin of water, or wear swimming goggles!

Historically, onions originate from Central Asia where they have been consumed for over 6000 years. Their presence is also noted in the tombs of pharaohs, where their therapeutic and gustatory virtues were already recognised. The Romans later introduced onions throughout Western Europe. It is also worth noting that Christopher Columbus introduced onions to the Americas during his second voyage.

Harvesting: White onions are harvested in spring when the foliage is still green. Coloured onions (yellow and red) are harvested in summer when the stems are completely dry and lying flat on the ground. Gently pull them out and leave them to dry for two to three days on the ground in the sun. Remove the 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 it, you can make a braid and hang the obtained bunches. Otherwise, cut the leaves and store the onions in a dark, cool, dry, and well-ventilated place. Check beforehand that they have not been bruised to avoid rotting, which could contaminate the entire harvest.

A Gardener's Tip: alternate rows of onions and carrots to keep carrot flies and onion flies away. Additionally, onions thrive in the company of beets, strawberries, and lettuces.

Planting and care

Onions thrive and grow in all types of soils, preferably light and well-drained. The soil should not have received any fertilisation for at least a year. Choose a sunny spot. Onions are sensitive to excess moisture, which can cause the bulbs to rot. If your soil is very moist, add some sand to it. Planting on raised beds 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 tip facing upwards, by gently pressing them into the soil. Cover with a little fine soil, with the tip just above the surface. No watering is necessary.

Regularly hoe, especially in the beginning. There is no need for mulching.

Onions dislike excessive nitrogen, so avoid planting them after green manure or legumes from the Fabaceae family (beans, peas, fava beans). Rotate approximately every 5 years before cultivating onions again.
