Growing Notes
Transplant (recommended) - Sow into preferred seedling container, 8-10 weeks before planting out. Light is required for germination. Cover seeds with a thin layer of vermiculite to retain moisture and hold seeds in place. Bottom water or mist lightly to avoid covering seed. 3-5 weeks at 55-65°F (13-18°C) in full light are ideal conditions for seedling development. Harden off seedlings and transplant outdoors.
Direct seed - Late spring, early summer, or fall.
Harvest
When pollen is visible on the flowers. Hang to dry.
