Summarize this article:

Use room temperature water. Wet the soil so that it is moist, but not overly wet. Shake the container so that the seed moves deeper into the loose soil. Place the jar or bag in the refrigerator to start the stratification process. This cool, sprouting process germinates the seeds so that they can be planted and grown into a tree.

Summary:
Soak the seeds overnight in the glass of water that you just filled. Fill a plastic bag or a canning jar two-thirds full of rich compost. Place the seed or seeds inside the compost and seal the plastic bag or jar. Turn your refrigerator to about 40 degrees Fahrenheit (4 Celsius).
