Sow in a propagator on a windowsill or one seed per 5cm pot in a greenhouse at approximately 18-21 degrees using a good quality compost. Cover seeds with 2.5cm of compost (germination 7-14 days). Grow on carefully planting out when the risk of frost has passed, allowing 40cm between plants each way in a block pattern to aid pollination. Can also be sown directly outside, 2 seeds per station, thinning to the strongest seedling.
Ideal for beds and borders. Prefers full sun. Always plant corn in 'blocks', not rows, as they are pollinated by the wind not insects
