"To guide the reader in growing ginseng, I have drawn from my own hands-on experience, from discussions with other experienced growers and agriculture professionals, and from my own observations of ginseng operations throughout the United States, Canada, and Australia."
"As this revised edition of Growing & Marketing Ginseng, Goldenseal & Other Woodland Medicinals is about to go to press, the prices being paid for wild ginseng are higher than ever before. While this certainly makes woodland ginseng growing even more attractive, should roots continue to bring such high value in the future, wild populations could be threatened by overharvesting, and the United States Fish and Wildlife Service might well feel compelled to prohibit the export of wild ginseng in order to protect the plant. Growers are therefore advised to proactively document their purchases of planting stock and their growing operation in order to be able to prove that their roots were not foraged from wild populations. Increased production of high-grade roots by woodland growers is the best way to keep supply in balance with demand, thereby keeping prices down and protecting the still widespread populations of wild ginseng."
The picture at the top of this post was taken from a video of an interview of Scott Persons by Accem Scott. I think you might find it interesting: Link to Video.
