A big leafed cold weather variety. A foolproof way to grow healthy kale seedlings is to sow them in module seed trays – sow one or two seeds in each module 1.5cm deep. Thin out the weaker seedling. Kale will germinate in about a week and will be ready for planting out about 6 weeks later. Make sure to harden off early sowings carefully.
Since they are a hungry crop, add plenty of compost or manure to the soil the previous autumn. Space plants about 50 cm apart in rows about 60cm apart. Include kale in your brassica rotation – do not plant them where there have been brassicas for at least 3-4 years previously.
