Sakura Germination:
1) Cut several small but not too deep places into the hard shell. This will allow proper water penetration.

3) Place them into the fridge around 40 degrees for 90 days. Place a few small holes in the bag so it can breath just a bit, and be sure to check it periodically to be sure it doesn't dry out. Keep it moist at all times, but never wet.
4) Plant appx. 1/4" inches deep in moist well draining soil. Use a heated propagator mat for the first few weeks keeping the soil & roots around 70 degrees F.
