Sowing & Growing

Sow February to April, early sowing can be made under glass in pots or seed trays, sow seed on the surface of seed sowing compost and lightly cover with a sprinkling or vermiculite or compost, and place at a temperature of 14C.

Outdoor sowings can be made in April , sow seed thinly in shallow drills 1.5cm deep, with rows spaced 30cm (12in) apart.

Greenhouse sown seedlings can be pricked out into individual pots or modular trays. Move plants to a cold frame in April to harden off before planting outside 15cm apart. Outdoor sowings can be thinned gradually until plants are 15cm apart, then leave to mature as smaller bulbs for storing.

Maturity is expected August to September, pull the thinning’s carefully and remove from the site to avoid attracting onion fly. Thinning’s can be used as salad onions.

Growing Conditions

To successfully grow Sonic onions, consider the following conditions:

• Light: Sonic onions thrive in full sun, requiring at least 6 to 8 hours of direct sunlight each day for optimal growth.
• Soil: Well-draining, fertile soil rich in organic matter is essential. A slightly acidic to neutral pH (6.0 to 7.0) is ideal for healthy growth.
• Watering: Consistent moisture is crucial for onions. Water regularly to keep the soil evenly moist, especially during dry spells, but avoid waterlogging, which can lead to rot.

Care Tips

• Fertilization: Use a balanced fertilizer or one high in nitrogen to promote healthy leaf growth. Apply it according to package instructions, typically every 4-6 weeks during the growing season.
• Spacing: Space onion sets or seedlings about 4 to 6 inches apart to allow for proper growth and air circulation.
• Weed Control: Keep the area around the onions free of weeds, as they can compete for nutrients and water. Mulching can help suppress weeds and retain soil moisture.

Harvesting

Sonic onions are typically ready to harvest when the tops begin to yellow and fall over, usually around 100 to 120 days after planting. Gently lift the onions from the soil using a garden fork or your hands, being careful not to damage the bulbs. Allow them to cure in a dry, shaded area for a few weeks before storing.
