Sowing Indoors

Sow seeds individually in small pots of moist compost 1cm deep. Place in the warmth 15-18c. Grow on under cool, light conditions, but not in direct sunlight. Gradually accustom young plants to conditions outside for 2-3 weeks before planting out to their cropping positions, when danger of frost has passed. To ensure good pollination, plant in blocks, allowing 45cm (18in) each way between plants.


Sowing Outdoors

Water sowing positions well, then sow two seeds 2cm deep at stations 45cm (18in) apart each way. Keep soil moist until seedlings are well-established. When seedlings are around 8cm (3in) high, discard the weaker at each station and leave the stronger to develop. Do not transplant weaker seedlings – they do not thrive.

Growing Tips

Do not grow other varieties of sweet corn nearby as they will cross-pollinate with this variety. If planting out before the risk of frost has passed, cover with horticultural fleece.
