The Borettana onion is a unique variety valued by gourmets and gardeners alike for its distinctive appearance, delicate taste, and versatility. It produces medium-sized, flattened bulbs with smooth, golden-copper skin that tightly protects the flesh from drying out. The interior is firm, juicy, and creamy-yellow, offering a subtle hint of sweetness. This profile makes it excellent for grilling as well as for homemade preserves, particularly when pickled in vinegar. Upon heating, this onion develops a deep, caramel aroma, becoming milder and exceptionally full-flavoured. This variety is also distinguished by its excellent storage capabilities, retaining freshness, firmness, and beautiful colour even after several months.
Seeds should be sown at a depth of approximately 2 cm. Placing them in the soil at this level ensures even emergence, stable rooting, and proper plant development. Sowing too shallowly may cause drying, while sowing too deeply can delay germination, so it is worth paying attention to the correct depth during the process.
Sowing is carried out from April to June, when the ground is already warm and moist. During this period, onions have the best conditions for growth and bulb formation. Early sowing allows for a harvest as soon as the middle of summer, whereas later sowing ensures fresh bulbs for autumn.
During sowing, it is worth maintaining a spacing of 30 x 3 to 4 cm. This arrangement enables plants free access to light and nutrients, allowing the bulbs to develop evenly and achieve the flattened form typical of this variety. Appropriate distance between rows also facilitates care, weeding, and subsequent harvesting.
The harvest period falls from July to September, when the green tops begin to break over naturally and the skin acquires an intense, copper-gold shade. This is a sign that the bulbs have reached full maturity and are ready for consumption or storage. After pulling, it is worth drying them slightly in an airy place, which further extends their durability.
The Borettana onion grows best in full sun, in a warm and airy position. Sunlight promotes natural drying of the bulbs and deepens their colour. The soil should be moderately compact, slightly moist, with a high content of humus and nutrients. Cultivation from direct sowing into the ground is easy and requires no special experience; regular watering and gentle weeding are sufficient. This is an ideal variety for beginner gardeners and lovers of natural flavours who wish to enjoy their own aromatic onions throughout the season.
