How to germinate Acer shirasawanum seeds:
Sow thinly at 6 mm deep in a sandy peat layer; tamp firm. Cold stratify for 60-120 days. Keep moist. Add a thin layer of fine mulch to anchor seed down. Don’t let germinating seed freeze, dry out or migrate onto the surface as this is fatal. After cold stratification period is over, expose to spring conditions to promote germination. Good indirect light is best for seedlings. Protect seed/seedlings from rodents. I prick out seedlings when dormant and grow in individual pots for first 2-3 years for best results.
