Where to Sow

Early sowing can be made under glass in pots or seed trays, sow seed 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 seedlings can be pricked out into individual pots or modular trays. Move plants to a cold frame in April to harden off before planting outside 15cm (6in) apart. Outdoor sowings can be thinned gradually until  plants are 15cm (6in) apart, then leave to mature as smaller bulbs for storing.  

Handy Tip

Onion seed does not like being sown in cold wet soils. It may help to sprinkle some dry compost into the seed drill before sowing.
