Answer: Seeds of dogwood (Cornus) require alternate warmth and chilling prior to successful germination. Sow on the surface of well-draining growing medium, and keep at 70F for two months, then refrigerate for 3 months. After the pre-treatment seeds will germinate in 90-730 days when kept at 50F-60F.
Be sure to keep soil moist but not soggy wet throughout the germination process.
Good luck with your dogwood!
