Well,
I guess that the trees were apparently flurishing in the soil they were in. The soil mixes we use vary from a little organic to none. Indeed, many Satsuki azaleas are planted in pure kanuma. Why do you believe that a tree in a pot requires organic material in the mix? Indeed many of the very best trees are grown in a mix of akadama-pumice-volcanic- some are grown in pure river sand.

I think that experience in soil choices will certainly provide better results than saying there is only one way to do things. Perhaps you can get together with some of your more expereinced club members and get help for soils that work in your area.

Best of luck with your trees.
John
