Sowing Instructions :
Sow seeds directly outdoors in a Sunny site with good soil in mid-to-late May. Seed can also be started indoors in a soil-less mix 8 weeks before last frost date. Keep temperature at 21 C (70 F) for the 10-14 day germination period, grow on at a slightly cooler temperature before hardening off and transplanting outside after the danger of frost has passed. Sow seed 3 mm (1/8″) deep and 2.5 cm (1″) apart then thin to 25-30 cm (10-12″) apart in the garden.
