What to expect
Tips
Some sources recommend cold stratification (39-45°F for 3 months), while others indicate seeds do not require cold stratification. Hot water soaking and mechanical scarification enhance germination. Keep substrate moist but not wet. Seeds have hard seed coats and may take 1-4+ years to germinate naturally in field conditions, but respond well to pre-treatment.
