The Agostana onion is a unique variety characterised by snow-white skin and a perfectly spherical shape, delighting with its delicate, slightly sweet taste. It stands out not only for its appearance but also for the excellent structure of its flesh, which is firm, juicy, and mild in flavour. This onion works perfectly as a fresh addition to salads, sandwiches, or grilled dishes. Thanks to these features, it is an excellent choice for those seeking high quality and a subtle aroma. Agostana is a medium-early variety, yielding crops approximately 130 days after sowing. It is perfectly suited for both direct consumption and short-term storage, retaining freshness, firmness, and full flavour for a long time. This variety is valued by gardeners for its reliability and high yield, and by cooks for its taste and aesthetic qualities.
Sow Agostana onion seeds at a depth of 1-2 cm. This depth allows for even emergence and proper development of young plants, translating into an abundant and uniform yield.
Sowing directly into the ground is carried out in April, when the soil is already warmed and moist. This is the ideal moment to ensure the onion has the best conditions for germination and active growth.
Seeds are sown under covers as early as March. This allows for earlier harvests, and young plants are stronger and establish faster after transplanting to the ground in spring.
Plant Agostana onion seedlings in May, when the risk of frost subsides and soil temperature favours the rapid rooting of young plants.
During planting, maintain a row spacing of 25-35 cm and a distance of 5-8 cm between plants. This layout guarantees every onion sufficient light and space, enabling it to produce large, well-shaped bulbs.
The harvest of Agostana onion falls from August to September. This is the time when the bulbs fully mature, take on an intensely white shade, and reach optimal hardness. In appropriate conditions, they will retain freshness and taste for long weeks.
The Agostana onion grows best in full sun, in fertile, light soil rich in humus. A substrate pH close to neutral is most beneficial. During growth, the plant requires moderate watering; too much water can lead to root rot, while a shortage will stunt bulb growth. After emergence, it is worth thinning the seedlings to ensure free development. The first beautiful, large onions can be harvested even at the end of July if the weather is favourable. This variety rewards the grower with an abundant yield with minimal work; good soil, appropriate care, and regular weeding are sufficient.
