Axe, you ridicule another poster for stating his opinion, yet you get on here and whine when someone does that to you. I never said anything about DNA or plants reverting,mutating, etc........ Ever heard someone say right plant,right place? That's what I was getting at. Now who was running off on a tangent. In my opinion, you will never create the perfect soil, you have to learn to work with what you have. Can you make improvements to soils? Yes, if you want to spend the time and money.
