Description

Sow summer cabbage indoors seed from February to May. Alternatively direct sow outdoors from late 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 23cm (9") between rows. Indoors, sow seed at a depth of 12mm (1/2") in trays of free-draining, seed sowing compost and cover with a layer of vermiculite. Place in a propagator or seal container inside a plastic bag at a temperature of 20-25C (68-77F) until germination which takes 4 -7 days. Once germinated, grow Cabbage plants on in cooler conditions until all risk of frost has passed and plants are large enough to be transplanted with 2-3 true leaves. Gradually acclimatise them to outdoor conditions over 7 - 10 days before planting cabbage in moist, rich, well-drained soil in full sun. A fertile soil is essential as cabbages require high levels of nitrogen. Prepare the soil in early spring by adding plenty of well-rotted farmyard manure to the soil to improve its structure and fertility. Apply lime to acid soils to reduce the acidity and lessen the risk of clubroot. Plant cabbages at a distance of 50cm (20") apart and cover with a protective netting or fleece to prevent attack from birds and insects. Place a collar around the stem of each plant to prevent cabbage root fly attacks. Water the plants thoroughly after planting.Product specifications:. Position: Full Sun.
