Spring Onion
Allium cepa
Spring onions are fast-growing, mild-flavoured onions grown for their green stems and small bulbs. They are easy to grow and can be sown in succession for a continuous harvest. Hardy varieties can even be sown in late autumn to overwinter for an early spring crop. Spring onions don't take much space and grow well in containers or between slower-growing vegetables.

Step-by-step guide to growing spring onions sown outdoors in spring and summer.
1 Sow Seeds Outdoors
March to June is the main period to sow spring onions in Woodrising. Sow seeds in rows about apart and deep. Keep the soil moist and weed-free. For a continuous supply, sow new batches every few weeks.
2 Thin Seedlings
Once seedlings are a few centimetres tall, thin them to about apart. Remove the weaker ones carefully to avoid disturbing the remaining plants. Thinning gives each spring onion space to grow to a good size.
4 Harvest
Spring onions are usually ready to harvest about 90 days after sowing. Pull them up once they reach pencil thickness. Harvesting can start from June and continue until September for later sowings. Spring onions are best used fresh, as they do not store for long.
