Onion tips: For the best onions sow in January indoors with heat. Alternatively they can be sown from February under cover. They should be transplanted in April to their final growing position.

Onions can also be direct-sown from March in drills 25cm apart, spacing seeds 1cm apart within the drill. They should then be thinned to 10cm spacing once established.
