I've piddled around with growing wild simulated ginseng for a lot of years now. At first, it was rake and scatter, but when that came out too thick, and blighted out and died, I went to planting it by hand one seed at a time, very thin in good natural habitat and I had some success doing that. This year, I'm planting again and I got one of those ECF seeders from BCastle on here. I'm in no way affiliated with him, but I gotta say this is the best investment I've ever made for planting the way I like to. I can get right up in the underbrush and plant the seeds in exactly the kinds of places I typically find good wild ginseng and without ever even bending over, plus it's at a good depth and much quicker than by hand too. Might look into it.
I use the Earthway to plant woodsgrown in tilled beds. I've tried to use it to plant wild sim and it just doesn't seem to work too handily when you are dealing with rocks, limbs, twigs and roots which you have in the woods. You can clear (rake or blow) off an area and depending on your ground and the ground cover get hit or miss results planting wild sim with the Earthway.
