Germinating a copper beech seed

Good morning. This fall I collected 75 seeds from a giant, beautiful copper beech. I refrigerated them for 3 months. I then put them in a wet paper towels inside a baggie and they sat at 80 degrees for 2 weeks. One of them finally germinated. I just put it in soil 1/2 inch deep. Am I doing this correctly? What else can be done? Thank you.
