Drop the seeds into a bucket of water overnight. The seeds that are floating are likely not viable.
Plant only the seeds at the bottom of the bucket.
Fill 4 inch plastic pots with half peat moss and half perlite. Lay the seed on the soil surface with the rounded end is parallel with the surface.
Push the seed into the soil so it is 2/3 of the way below the surface. Water the pot until the water drains out.
Maintain a constant moisture but not soggy.
Keep in a bright and sheltered area and maintain temperatures between 70 and 90 degrees F.
You should start to see signs of germination in 2 to 3 months.
Another 2 years in the shade and they are generally ready to go to the ground in the fall of their 2nd year.
