For pots and patio containers sow the seed direct into pots and place on a windowsill or in a greenhouse at approx. 13-18°C (55-65°F), 3 or 4 seeds to a 7.5cm (3") pot. Germination takes 10 - 14 days. Grow on and plant out after careful acclimatisation to outside conditions, spacing 45cm (18") apart.
