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

I was taught from the beginning of my experience over 25 years ago that soil should be made of three things: crushed granite, turface, and ground up pine bark.

Here in Georgia there are a lot of quarries where granite can be found, but I prefer to buy already graded Grani-grit which comes from North Carolina Granite Co. in Mount Airy in 50 lb. bags. The dust has to be sifted out.

I use Turface MVP which comes in 50 Lb. bags, also requiring sifting.

I use Nature's Helper which is ground up pine bark in a 3 cubic ft. bag from Home Depot, but also is sold in nurseries. Also requires sifting to get the dust out and for grading.

This has worked very well for me, and I have over 100 trees in this mixture.

I'm going to experiment a little with an oil-dri product that is NAPA's own brand in the spring on some "yard trees" just to see how it works as a substitute for Turface.
