I have a lot of oak on my place (white, red, black, post, chestnut, etc)..
White and Chestnut oaks are the majority. I think the Chestnut Oak has stouter leaf than the white oak does.
I would say that on most of my place oaks make up 80% of trees.
Good for Timber but probably not as good for ginseng.
I do have good germination results (lots of 3 leafers) so I can't say that I have seen a lot of problem with oak leaves keeping them from coming up.
I have planted hankins method, and rake and scatter, and don't mulch the leaves.
I am sure there are areas where the leaves could really pile up and keep em down, but I have not seen that problem on hillsides where I plant. I don't plant a lot of flat areas, pretty much all hillsides with some good tilt to them.
