Where to Sow
|April to June
||May to July
||July to September
Early sowings can be made under glass at a temperature of 16 C, sow 3 seeds per 8cm (3in) pot filled with seed sowing compost. Outside sowings can be made from May onwards into the growing site 5cm (2in) deep. Sow 2-3 seeds every 20cm(8in) apart with rows spaced 60cm (24in) apart.
What to do next
Seedlings sown under glass should be gradually hardened off before planting outside in late May to the above spacing, once all risk of frost has past. Provide support by canes or netting for plants to climb. Water regularly during dry weather.
Sow a few seeds early in large containers under glass for an early crop of sow late summer under glass to extend the cropping season into autumn.
