Seed Treatment (Stratification)

  • Cold Stratification: 2-4 week cold period (moist stratification in the refrigerator).

How to Plant:

  1. Sowing Time: Start indoors 6-8 weeks before the last frost or direct sow in early spring or fall.

  2. Soil Requirements: Prefers well-draining, light, and fertile soil with a pH of 6.0-7.5.

  3. Light Requirements: Seeds need light to germinate, so do not bury them.

  4. Seed Depth: Lightly press seeds onto the soil surface—do not cover.

  5. Watering: Keep soil moist but not waterlogged until germination occurs.

  6. Germination Time: 10-21 days at temperatures of 60-70°F (15-21°C).

  7. Spacing: Once seedlings are established, thin to 6-12 inches (15-30 cm) apart.
