Seeds are typically sown 6-8 weeks before the last frost date. [9] Seed germination usually occurs between 6-10 days. High yields of this plant are achieved by maintaining an appropriate soil pH level of 6.2-6.8. [11] Application of Fertilizer is recommended to the soil when the plant begins flowering.
