How to Grow
600 seed/gram. Do not rush planting. As Basil loves warm soil and warm temperatures, it will languish if temperatures are below 15 C (60 F). Sow seed directly outdoors in a sunny site with average soil in late May and June. Plant seed 4 mm (3/16″) deep and 6 mm (1/4″) apart. Thin to 25-30 cm (10-12″) apart in the garden. Seed can also be started indoors in a soil-less mix 4-6 weeks before last frost date. Keep temperature at 21 C (70 F) for the 7-10 day germination period, then grow on at the same temperature before hardening off and transplanting outside after the danger of all frost has passed.
