Start seeds indoors 6–8 weeks before your last frost date or sow directly outdoors after the danger of frost has passed.

Keep soil consistently moist during germination but not waterlogged.
Maintain soil temperatures between 65–70°F for optimal germination.
Seeds typically germinate within 7–14 days.
Thin seedlings as needed to ensure good airflow and healthy development.
