bonsaiTALK Community - View Single Post - crushed granite as a soil amendment?

Thanks for the info. The stuff I have is pretty hard, not any crumbling. It appears to be what it says it is, crushed granite. Decomposed granit would be found crumbling on it's own and the stuff I am using has definitely been mechanically helped to form small granules. I started using it because it was recommended in John Naka's book. It is quite sharp and works well to split roots that push on it. I am not sure of its exact origin. The bag says Granite City Grit.
