Tips & Advice:
Sowing Indoors
Sow seeds individually in small pots of moist seed compost 2.5cm deep. Place in the warmth, 15-18°C. Grow on under cool, light conditions, but not in direct sunlight.
Hardening Off/Planting Out
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 each way between plants.
Sowing Outdoors
Water sowing positions well, then sow two seeds 2.5cm deep at stations 45cm apart each way. Keep soil moist until seedlings are well established. When seedlings are around 8cm high, discard the weaker at each station and leave the stronger to develop. Do not transplant weaker seedlings as they do not thrive.
