Sowing Outdoors

Sow thinly in pre-watered shallow drills, and cover with a little more soil. Allow 20cm (8in) between rows.

Keep soil moist until seedlings are established.

No need to thin - just pull when onions are young and thin. Sow little and often for a continuous supply throughout the summer.

Autumn sowings may benefit from cloche protection in severe weather, and should be ready in March or earlier in mild weather.
