The digging itself is not hard, but you need to be careful with the root....broken roots mean less money. A lot of the time and effort involved in gathering wild ginseng is spent in walking, looking for the plant. Obviously, if you're digging what you planted, then that won't be an issue.
If the roots are one or two years old, then yes, they can be transplanted into the wild. And, depending on the growing method utilized, they may take on the desireable characteristics of a wild plant, provided they are left to grow for some years.
Ginseng buyers are quite aware of the differences between wild, and fully cultivated roots, and will price them accordingly. That's why I am going with the wild-simulated method.
