Rootman and Others,
I transplanted 50 beautiful roots in a small shade bed in a spot in my shade garden a few years back. It was a clay based soil so I tilled in some coarse sand and some peat. I had really bad results with it. This stuff set up like concrete. I mean when I first tilled it I thought I created the perfect mix. I tilled it deep and when I was done it looked loose and loamy.
I recently read that tilling can often result in a soil that sets up like concrete. Well I learned the hard way that they are right. Lost every one of those 50 roots and they were all in the 20 to 30 year old range. It made me sick.
This is contrary to what most people think. I mean tilling makes the soil loose at first. But I had no idea it could lead to compacted concrete hard soil in the years to follow.
I wonder if one were to mix in some lime stone gravel if this would help. I think the soil in the woods has enough compost or organic matter in it most often that tilling probably does not end up compacted. However, tilling a clay based soil and planting ginseng seeds in it is a different story.
Lets face it, if you till a ginseng bed in a clay based soil you only get to till it the first time. Once the seeds are planted you cannot till it again obviously.
I have another larger area in back that I tilled in shredded leaves each year and have done it for the past 5 years. It was my veg garden. The soil was clay based so I mixed in some coarse sand along with the hundreds upon hundreds of large trash bags filled with mulched leaves. I mean I used to go around the neighborhood in the fall and I put the bagged shredded leaves in my truck and brought them home and tilled them in. Well this veg garden got tilled every year but the trees I planted nearby eventually made the garden shaded. So I thought this would make the perfect spot for ginseng, yellow root and blood root. I planted seed and roots and have had very little success.
After all that tilling and adding shredded leaves year after year the ground has once again set up like concrete. A couple links below on this.
