Description
Very resistant species, requires little care and little water, intercropping is not indicated, renewal crop must not follow brassicaceae, patale and other liliaceae. The topping or twisting of the leaves at the base favors the drying of the bulbs.
this type of onion is sown from July to October, even in February-March, are harvested in spring and summer but have a poor shelf life, therefore they should be consumed in the short term. To extend the harvesting and consumption period, we recommend more graded sowing of the same variety and sowing several different varieties. During the thinning the spring onions are harvested.

Allium cepa, commonly known as the onion or bulb onion, is one of the most widely cultivated and economically important vegetable crops in the world. It is a biennial herbaceous plant belonging to the amaryllis family (Amaryllidaceae). Onion seeds germinate readily without dormancy at warm temperatures and are easy to grow from seed, making them ideal for home and commercial gardeners.

Growing Tips
Sow indoors 8-10 weeks before the date of the last frost; seeds germinate fastest at 68-77°F (20-25°C) in darkness. Keep soil consistently moist but not waterlogged during germination. Use a heat mat to maintain warm soil temperatures for faster, more uniform germination. Cover seed trays with a propagation dome to retain moisture until germination occurs. Thin seedlings to prevent overcrowding and strengthen growth. Transplant seedlings outdoors when soil temperature reaches at least 50°F (10°C), avoiding exposure to prolonged temperatures below 50°F as this may cause bolting. Onion seeds are short-lived; store unused seed in cool (below 40°F/4°C), dry conditions to preserve viability for up to 3 years.
