Successional Sowing
Sow every three weeks from late winter to late summer to ensure a continuous supply. Sow thinly in rows 10cm apart, 1cm deep. No need to thin — simply pull as needed when pencil-thick.Overwintering Varieties
Some varieties (such as 'White Lisbon Winter Hardy') can be sown in August or September under cloches for early spring harvesting — invaluable for the hungry gap.Soil: Any fertile, well-drained soil.
