Gereral growing instructions for Broccoli and Calabrese seeds.
Broccoli, Calabrese - there is a difference of course but most people grow one or the other for their nutritional value so we treat them the same.
Outdoors: sow thinly, March-June, in a seed bed, 1.5cm (?") deep, directly into finely-prepared, well-cultivated, fertile soil, which has already been watered. Seedlings usually appear in 14-28 days.
Transplant 45cm (18") apart when plants are about 10cm (4") tall. Water well until plants are established.
Allow 45cm (18") between rows. Plant firmly and water well. Sowings made every three to four weeks will ensure a continuous supply into autumn. Or sow indoors, February-April, 0.5cm (?") deep, in a tray of compost.
Water well and place in a cold frame or unheated greenhouse. Keep moist. Transplant 5cm (2") apart to other trays, when large enough to handle. Gradually accustom young plants to outside conditions (avoid frosts) before planting out, April-June, into well-cultivated, fertile soil.
Sow thinly, March to June, 1.5cm (??) deep, in a seed bed. Keep soil moist. Transplant seedlings to their growing position in July, spacing 60cm (2?) apart. Plant firmly and water well until established. Harvest: September-March. Pick the young shoots regularly to be sure of getting the best flavour and to encourage further cropping>>>>>>>>>
