Seed Treatment
Cold Stratification: 14–28 days of cold stratification by mixing seeds with moist sand and refrigerating at 35–40°F (2–5°C).
? If seedlings sprout in the bag, gently transplant them into pots or the garden immediately.
Optimum Temperature for Germination
15–20°C (59–68°F)
Keep the soil lightly moist throughout the germination period.
Germination Time: up to 42 days AFTER stratification
Light Requirements

Use grow lights to maintain 12–16 hours of light per day.
Press them gently onto the soil surface — do not cover.
