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, 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. Late Sowings may benefit from cloche protection during severe winter weather.

Handy Tip

Ideal for successional sowing.
