It is hard to say for sure just looking at a picture if ginsing will do well. Shade and even the mix of trees looks good enough but I have seen thousands of acres that looked good enough for ginseng, even finding some decent companion plants, but not one single stalk of seng growing there.
The absolute best sign is if you find some wild ginseng growing there already.
Have you found any ?
If not, then I would say the next best sign would be if you have some of the best companion plants growing there, maidenhair fern, baneberry, blue cohosh, yellow lady's slipper - with maidenhair fern being (in my opinion) the best of those.
I have some places that I have planted that look very similar to yours, and the first year 3 leavers came up and looked Ok, but even with applying gypsum yearly they have just never done much. Still very small, and spindly 2 prongs after 3 years. These are places where there was no wild ginseng growing but I tried it anyway... and well just have not had much luck with that.
All of the areas where I have had good luck or the best luck were areas where I had some wild ginseng growing already.
A soil test would be a good thing to do before you decide to plant. If you have calcium over 2000 ppa you might be Ok but still it could be too dry, to hot, to wet, etc...
I would advise to start small, space them out good, and after about 3 years you will know for sure whether it is going to work there or not. If things are progressing right along after 3 years, then you can get more serious about it.
Good Luck
