    • Soak seeds in warm water for 4–6 hours before sowing.

Sowing Instructions

  1. When to Sow:
    • Indoors: Start seeds 6–8 weeks before the last frost date.
    • Outdoors: Direct sow in late spring when the soil has warmed and frost has passed.

  2. Soil Requirements:
    • Prefers light, well-draining soil.
    • Tolerates poor soil, but performs best in moderately fertile soil.
    • Ideal pH: 6.0–7.0.

  3. Light Requirements:
    • Requires full sun (6–8 hours daily) for best growth and flowering.

  4. Sowing Depth:
    • Sow seeds ¼ inch (6 mm) deep.
    • Cover lightly with soil and gently firm.

  5. Watering:
    • Keep soil evenly moist until germination.
    • Once established, plants are drought-tolerant — avoid overwatering.

  6. Germination Time:
    • Germinates in 7–14 days at 70–75°F (21–24°C).

  7. Spacing:
    • Thin or transplant seedlings to 10–12 inches (25–30 cm) apart for bushy growth and airflow.
