Brassica oleracea var gemmifera
One of the oldest known varieties, very rare and hard to find. This variety is compact with heavy yields, sprouts are dark green and not too very big. This is a Midseason variety, harvested between November and December. This variety is a great freezing variety for long storage. Dependable yield. Great for small gardens.
Sow Brussels Sprout seed indoors from February. Alternatively direct sow outdoors from March into a well-prepared seedbed, for transplanting to their final positions later on. Sow at a depth of 13mm (1/2″) and distance of 30cm (12″) between rows. Indoors, sow seed in 7.5cm (3″) pots or trays of free-draining, seed sowing compost, and cover with a 6mm (1/4″) layer of vermiculite. Place in a propagator or seal container inside a plastic bag at a temperature of 15C (60F) until germination which takes around 7 days. Once germinated, grow Brussels Sprouts in cooler conditions until all risk of frost has passed and plants are large enough to be transplanted. Gradually acclimatize them to outdoor conditions over 7 – 10 days before planting Brussels Sprout plants outdoors in the firm, rich fertile, well-drained soil in full sun. Prepare the soil in advance in early spring by adding plenty of well-rotted farmyard manure to the soil to improve its structure and fertility. Plant brassicas at a distance of 60cm (24″) apart and cover with a protective netting or fleece to prevent attacks from birds and insects. Water the plants thoroughly after planting.
