Seed Treatment

  • Cold Stratification:

    • Store in the refrigerator (34–40°F / 1–4°C) for 4–6 weeks before sowing.

Sowing Instructions

Indoor Sowing (Recommended)

  1. Timing: Start seeds 8–10 weeks before the last frost.

  2. Containers & Soil: Use a well-draining seed-starting mix in trays or pots.

  3. Sowing Depth: Surface sow the seeds—do not cover them, as they need light to germinate.

  6. Germination Time: 3–6 weeks.

Outdoor Sowing (Optional)

  1. Timing: Sow in fall or early spring to allow natural stratification.

  2. Location: Choose a partially shaded to full shade area with well-draining, humus-rich soil.

  3. Sowing Depth: Surface sow and press seeds lightly into the soil.

  4. Moisture: Keep soil consistently moist until germination.
