Sow very thinly, 13mm (½in) deep in drills 45cm (18in) apart in soil that has been raked to a fine tilth. When large enough to handle, thin seedlings to 15cm (6in) apart and use as ‘baby leaves’. Must be kept well watered or will run to seed and be inedible. TIP - Seed is very small so mix with some dry sand for easier sowing. Harvest young leaves as required, picking only a few from each plant. Pinch out flower buds to prolong cropping. Sowings made in late summer will carry on cropping into winter if given protection by cloches.
