Billygoat,
That flakey bluff rock that I mentioned I planned to add must be about the same as what you mentioned. I found some really good seng growing in it so I am going to add some of that.
I may also put some drywall board (gypsum board) pieces in the bed to to provide a continuous supply of gypsum (calcium). Each time it rains on it, should make a little more gypsum available.
Classicfur,
I have sent off the soil test, but ours has to go to Nashville TN and per or Local Agg office it can take up to 2 weeks go get that back.
I do have a PH tester and the PH shows 5.8 so I should be Ok on that. Scott recommends a low ph in the 5.0 range but I have seen others recommend up in the 6.5 range.
Hopefully my 5.8 will be Ok there.
Also - I am only talking about this one seed producing bed that I am going to spruce up like this, not my entire 30 acres.
I also know what Ginseng does on this 30 acres already - it grows Ok, but does not really flourish. I have never found a 4 prong in the woods here (only on that bluff where the soil is full of those flakey rock chips).
Fairly sure that means that most of the woods soil around here is a bit lower on calcium than seng likes.
There is some maidenhair fern and bainberry so has to be some calcium present, but it may be in the 1000-2000 lbs per acre range instead of up in that 4000-5000 range where Scotts book shows seng does best.
I will know for sure when the soil test comes in but in this small 4x12' seed producing bed I figure it can't hurt to go ahead and load it up on gypsum and rock chips.
Also on the roots - I am not really worried about the roots in this bed. It is for producing seed. I am going to transplant wild roots (nice 3 or 4 prong plant roots) into this bed and space them out about 1' each.
I figure I can get around 33 plants in the bed at that spacing, and if I eventually get 30-40 berries off each one that will be (around 2000 seeds) of my own wild grown seed that I can plant here on my place.
Her is a pic of what I have got done so far:
