What is the proper procedure for stratifying ginseng seeds?
This requires a lengthy answer. After looking at several books here in the library I found the information in American ginseng green gold by W. Scott Persons and I've attached relevant pages to this answer.
However, you may wish to learn more about ginseng. We have books in our library on this topic, including Ginseng dreams : the secret world of America's most valuable plant by Kristin Johannsen. You are welcome to visit our library to use material here. PHS members have borrowing privileges.
