I never really understood why people would use more than one type of inorganic material per mix. For example...some people use equal parts pine mulch, turface, and grit. Well...if the turface and grit are going to provide the same sort of drainage, why not use 2 thirds of one inorganic type and 1 third of the organic substance. Now that I have stated this, let me contradict myself.

I believe that each inorganic material does something unique. Turface provides great drainage, yet retains more water then say lava rock. Lava rock has a more rigid surface then say chicken grit. This will allow the roots to split and grip through the substance easier. So in fact it would be benificial to add more than one type of inorganic substance depending on the trees needs.

In closing, simple is better. The tree will grow in just about anything. It's health is dependant on the watering and feeding schedule.
