im no expert but i would imagine if you just dig carefully, very late in the fall you could have pretty good luck transplanting them. just bury them in a good spot with the new growth bud a couple inches below the surface cover with dirt, tamp it down, cover with leaf litter, and add a little water. good luck
guys if i dont him wrong please feel free to correct me
The only thing I'll add is to keep them out of the ground as short as possible. When I've transplanted roots, I usually bring them home and give them a quick rinse (mainly just to keep them from drying out) I then dry off the excess water with a paper towel, put them in a ziplock bag and store them overnight in a cool place (If it is cool outside I'll keep them there as long as it doesn't get close to freezing) the refridgerator is fine, but I've had good luck with a temp around 50 degrees so why change. I always try to get them back in the ground by the next morning. Have had really good results with this.
I'll agree with 5prong. I wouldn't suggest watering them after you plant them. Water causes all kinds of issues with ginseng if there is too much.
I would also caution you about digging the smaller wild plants for transplanting. Make sure it is legal to dig them before you do. In Ohio, a harvested plant must have 3 prongs. If it doesn't, you can't dig it even to transplant it into a bed.
