Sow outdoors April to September. Kale can be sown directly outdoors for ease, although plants may take a bit longer to get going and therefore crop slightly later. If possible choose a sunny location for best results. All brassicas like good fertile soil so it’s worth digging in a slow release fertiliser or some organic matter before you start. Sow directly where plants are to grow, 1.5cm deep in shallow trenches 45cm apart. Cover the seeds with fine soil and water well. Keep the soil moist and remove any weeds as they appear. When young plants are 10cm tall transplant them to a final spacing of 45cm apart. Plant them deep, right up to the first set of leaves and be sure to firm the young plants in well to prevent them from rocking in the wind, which can damage their delicate roots. Keep the soil moist and remove any weeds as they appear.
