Planting Instructions Plant seed outdoors as early in the spring as the ground can be worked. Just cover seed lightly and space 45 cm (18 in) apart. For earlier bloom start indoors 4 weeks before date of transplanting out in the garden. Start seed in 8 cm (3 in) jiffy pots or strips. Just cover the seed and keep the soil temperature at 22 C (72 F), it will germinate in 7 to 10 days. When plants are 10 cm (4 in) grow on in cooler conditions, 15 C (60 F). Transplant carefully as the roots do not like to be disturbed. Fertilize every 2 weeks with 10-52-17 and liquid seaweed for strong healthy plants. Garden spacing 60 cm (24 in) apart.
