Sowing Instructions :
Sow seeds directly outdoors in a Sunny site with average soil in mid-to-late May. Plant seeds 3 mm (1/8″) deep and 2.5 cm (1″) apart. Thin seedlings to 30 cm (12″) apart. Seed can also be started indoors in a soil-less medium 4-6 weeks before last frost date. Keep temperature at 20 C (70 F) for the 7-10 day germination period then grow on at a slightly cooler temperature before hardening off and planting out after the danger of frost has passed.
