1. Cold Stratification:
-
Cold stratify for 2–4 weeks.
-
Place seeds in a moist paper towel, seal them in a plastic bag, and refrigerate.
2. Timing:
-
Start seeds indoors 6–8 weeks before the last frost.
-
Alternatively, sow directly outdoors after the last frost when the soil is warm.
3. Soil Preparation:
-
Use a light, well-draining soil mix.
-
Ensure the soil is moist but not waterlogged.
4. Sowing the Seeds:
-
Lightly press seeds into the soil—do not cover them, as they need light to germinate.
-
Space seeds 1–2 inches apart in trays or 6–12 inches apart in the garden.
5. Temperature & Light:
-
Keep at 65–75°F (18–24°C) for best germination.
-
Provide bright, indirect light or use grow lights for 12–16 hours daily.
6. Watering & Humidity:
-
Keep soil consistently moist but not soggy.
-
Use a mist sprayer to avoid disturbing the tiny seeds.
7. Germination:
-
Seeds typically germinate in 14–21 days.
-
Once seedlings appear, remove any humidity dome and ensure proper airflow.
8. Transplanting:
-
Once seedlings have 2–3 sets of true leaves, transplant them into pots or directly into the garden.
-
Space plants 12 inches apart in a sunny location.
