When to Sow British Sweet White Pickling Onion Seeds in the UK
- Sowing Temperature: For optimal germination, maintain soil temperatures between 20-25°C (68-77°F). This temperature range ensures fast and even sprouting of seeds.
- Soil and Location: Choose a location with fertile, well-drained soil that receives full sunlight. These onions prefer soil enriched with organic compost to provide essential nutrients for robust growth.
- Seed Sowing Advice: Sow seeds at a depth of 1/2 inch. Keep the soil consistently moist but not waterlogged during the germination period.
Sowing Pickling Onion Seeds in Spring
- Indoor Start: Begin indoors in late winter to early spring, from February to April, to get a head start on the growing season. This is particularly useful in regions with shorter growing periods or cooler springs. You can use a propagator or a radiator to provide sufficient temperatures.
- Outdoor Transplanting: Transplant seedlings outdoors when they are sturdy enough and the risk of frost has passed, typically from late May to June. Ensure soil temperatures have consistently reached 20°C (68°F) for best results.
Growing Pickling Onions in Summer
- Direct Sowing: In areas with a longer growing season, direct sowing outdoors can be done in early to mid-summer, around June to July. This timing is ideal for harvesting in late autumn.
- Considerations: Ensure the soil is warm and there’s sufficient time for the plants to mature before the colder months. Summer sowing may require additional watering to keep the soil moist due to higher temperatures.
Growing Pickling Onions in Autumn/Winter
- Overwintering: In milder UK regions, sowing in autumn for overwintering can yield an early harvest the following year. Sow directly in the ground in September or October.
- Protection: Provide protection with fleece or a cloche as temperatures drop to shield young plants from severe frost and ensure their survival over winter.
Caring for Pickling Onion Plants & Seedlings
- Transplanting: When transplanting seedlings outdoors, plant them 2 inches deep and space the plants 2-3 inches apart to allow for ample growth. Ensure the soil is well-drained and rich in organic matter.
- Maintenance: Keep the soil moist but not waterlogged. Pickling onions benefit from regular watering, especially during dry periods, to develop their full size and flavor.
- Companion Planting: Pickling onions pair well with other herbs and vegetables, helping to deter pests and promote a healthy garden ecosystem.
- Harvesting: Harvest the onions when the bulbs are firm and the tops begin to yellow and fall over. Carefully pull the onions from the soil and allow them to cure in a warm, dry place.
- Storage: Freshly harvested onions can be stored in a cool, dry place. Properly cured onions will keep for several months.
- Watering: Ensure consistent moisture, especially during dry spells. Water regularly to keep the soil evenly moist but avoid waterlogging.
- Weeding: Keep the area around the onions free from weeds, which compete for nutrients and water. Gentle hand weeding is preferred to avoid disturbing the roots.
- Mulching: Applying a layer of organic mulch helps retain soil moisture, suppress weeds, and regulate soil temperature.
