Helping woodsgrown

I have a few patches of ginseng planted around my woods. A couple of them have quite a few plants but they are all very small, most are only about 6 or 8 inches tall. these plants are between 5 and 8 years old.
Should I move them, fertilize them, or just cover with mulched leaves again this fall?
Any help would be appreciated.
Thanks, gryhkl.

I have moved some that helped and others that went dormant or just died. Kind of wondering also.

Are they getting enough sun?
