I’ve had success by doing the following:

1. Wrap the seed in a wet paper towel

2. Place in small Tupperware container

3. Place container outside in sunlight

4. Wait for seed to split

5. Stick seed with wooden toothpicks and set on top of cup of water with water covering half of seed

6. Move to soil once seed starts to sprout from bottom (side of seed that is splitting)

Takes a while but rewarding!
