February to June
Approximately 12 weeks after sowing
Where to Sow
Early sowing can be made under glass in modules, sow 4-5 seeds per module on the surface of seed sowing compost and lightly cover with a sprinkling or vermiculite or compost, and place at a temperature of 14C. Outdoor sowings can be made in April onwards, sow seed thinly in shallow drills 1.5cm (1/2in) deep, with rows spaced 30cm (12in) apart.
What to do next
Greenhouse sown modules do not require thinning and can be moved to a cold frame in April to harden off before planting outside 7cm (3in) apart for clusters of salad onions. Outdoor sowings can be pulled and used as required.
Ideal for successional sowing. As a quick to mature crop, sow in between slower growing vegetables saving space.
