Sow 2.5cm (1") deep in final position, spacing seeds 25cm (10")apart.
To aid with pollination; plant in a block/square formation. Ensure each row is at least 50cm apart. Keep moist.
For succession, plant next crop when first plants are 20cm (8") tall. Water regularly, particularly in hot weather. Grow in a sunny position, sheltered from the wind, ideally in a well drained soil which has been enriched with well-rooted manure or compost. Fertilise reguarly.
