Setup, Compatibility & Care
Sowing Indoors: Start seeds indoors from January to March in seed trays or small pots filled with a good quality seed compost. Sow seeds thinly on the surface and cover with a fine layer of compost. Keep moist and warm (around 15-20°C) for germination. Once seedlings have a few true leaves, prick them out into individual pots or modules.
Transplanting: Harden off seedlings gradually before transplanting them into their final growing position outdoors in April or May, once the risk of frost has passed. Space plants about 15-30 cm apart in well-drained soil that has been enriched with organic matter. Ensure they have full sun.
Watering & Feeding: Keep the soil consistently moist, especially during dry spells, to encourage good bulb development. Avoid overwatering, which can lead to rot. A balanced liquid feed can be applied every few weeks once the bulbs begin to swell.
Pest & Disease: Monitor for common onion pests like onion fly and diseases such as downy mildew. Good air circulation and crop rotation can help prevent issues. Ensure soil is well-drained to reduce the risk of rot.
