Ginseng beds in Wisconsin are usually cultivated for three years before harvest, unless disease problems mandate earlier harvest.
We are parked this week at my uncle's farm just outside of Merrill, Wisconsin, which is in Marathon County, where we noticed the black mesh covering a section of his field. Ginseng! Of course I had to go online and check it out. I have learned some interesting things about ginseng, including what you have just read in the previous paragraphs.
