UK gardeners grow spring onions by succession sowing every 3-4 weeks from March to August, harvesting 8-12 weeks after sowing. White Lisbon is the most popular variety, ready in as few as 8 weeks. Overwintering varieties like White Lisbon Winter Hardy can be sown in August or September for spring harvests. Spring onions need no thinning when sown in clusters and grow well in containers, raised beds, and between rows of slower crops.
