Growing Guide
Sow seeds outdoors from March to August at 3 weekly intervals. For a winter and early spring crop sow seeds indoors in September or October and over winter. Whether sowing Spring Onion seed indoors or outdoors, sow liberally 1cm deep in drills 15cm apart. As the seeds are fine, water the drill prior to sowing seeds to prevent them from washing away. If required during dry spells, water as needed.
No thinning is required. However if plants are densely packed, thinnings can be a great addition to salads and stir fries before your main harvest .
TOP TIPS
Sow Spring Onion in succession for a continuous crop throughout the year. Many varieties, including those recommended and sold by Collie Flowers are good for overwintering, making a late indoor sowing in September or October for further harvest over the winter and early spring months. Spring onions will grow in most good fertile soil provided it is well drained.
Harvesting can usually start 9 weeks after sowing. Use a small fork or trowel to gently lift the plant out of the ground rather than pull and risk snapping it.
