Broccoli Cardinal Seeds
Info: Broccoli Cardinal is a beautiful purple variety, and one of the most flavoursome vegetables, sweet and delicate. The plants are very productive and produce medium to large purple spears on large framed uniform plants. This excellent late cropping variety can be harvested over many weeks.
Sowing & Cultivation: Broccoli is easy to grow; For early production, sow in March (1/2 inch deep) for planting April to harvest in November. For sowing outdoors, sow April to mid June for harvesting January to May. Broccoli is more cold-resistant than cauliflower. Broccoli grows best in partial-shade, in firm, fertile, free-draining but water-retentive soil. Avoid shallow, sandy soils, and exposed sites. Place the young plants at a minimum distance of 60 cm. Sprouting broccoli can be harvested when the flower shoots are well developed but before the flowers have actually opened. Cut the central spear with a sharp knife first as this encourages the side shoots to develop quickly. Regular picking extends cropping time.
