Increasingly popular vegetable for early summer to autumn harvesting. Once the central head has been cut, there are plenty of tender sideshoots over several weeks if cut regularly.Sow seed thinly 6mm (¼in) deep, and cover with a sprinkling of dry vermiculite or finely sieved compost. Place the seed and tray in a propagator or seal inside a polythene bag and keep at around 18-21?C (65-70?F) until seeds germinate. This will take about 4-7 days.When the seedlings are large enough to handle, transplant into 7.5cm (3in) pots or multi-cell trays. Plant out once the plants are approximately 10-15cm (4-6in) tall, into well-prepared soil allowing 38cm (15in) apart each way. Alternatively, sow thinly in a well-prepared seedbed, 1cm (½in) deep, and plant out when large enough to handle allowing 38cm (15in) apart each way. Sow successionally for extended harvest.To continue the organic life cycle of these seeds, gardeners should follow recognised organic growing methods, avoiding the use of artificial fertilisers and pesticides.
