Start inside 6-8 weeks before last frost, sowing 2-3 seeds in peat pots, thinning to one seedling after germination. Lightly cover seed and keep warm, 21-24°C (70-75°F). Will germinate in 10-21 days. May also be direct seeded after last frost in areas with long summers. Transplant 2 weeks after last frost into a full sun to part shade location. Space 6-8 inches apart. Do not allow to dry out, and fertilize regularly.
