Seed Advice for Successful Onion Cultivation

• Sowing Time: Sow the onion directly in the ground from March to April.
• Spacing: Sow the seeds in rows, spaced 25 cm apart.
• Covering: Lightly cover the seeds with about 1 cm of soil.
• Thinning: Thin the seedlings to 8 cm after 2.5 months, and again to 10 cm a few weeks later.
• Green Shoots: Don’t discard the green shoots! They’re delicious as an addition to salads.

Maintenance Tips

• Soil: Choose a light, well-draining soil and a sunny location.
• Weeding: Regular weeding is crucial, especially at the start of the growing season, to allow the plants to develop properly.
• Watering: Water moderately in the beginning of the season and only during severe drought later on.

Diseases

• Onions are particularly susceptible to downy mildew.
• Prevention: Apply well-rotted manure and spray regularly with horsetail decoction.
• Onions need a light, fertile, well-drained soil. Choose a sunny spot and avoid overly moist soil.

Harvesting

• Harvest Time: From late July to September.
• Encouraging Ripening: Bend the stems to the ground in August to stop growth.
• Storage: Let harvested onions rest on the ground for 48 hours (in dry weather) before storing them in a dry, well-ventilated place (e.g., hanging). This way, they can be kept for several months.

Companion Planting

• Good companion plants for onions include carrots (which act as a repellent against onion flies), tomatoes, beets, lettuce, and strawberries.
• Avoid legumes and other plants that add nitrogen to the soil.

Health Benefits

• Onions are a nutritious vegetable with numerous health benefits, including antioxidant, anti-inflammatory, antimicrobial, antidiabetic, and cardiovascular effects.
