Of the ten trees you repotted were they all the same species? How many were conifers and how many deciduous trees? The one that had the fiberous roots, what was it?
Please be patient with me, I simply want to know. What is it about akadama that makes it so good? What is it in it's content that makes it superior to anything we have in America?
Have you tried akadama over a period of time? If not, why argue from a point of ignorance against it?
I don't care what it "is", I care that it works. How? It holds water, it allows air circulation, it breaks down slowly over time, adapting with the roots. Newly potted trees have smaller root systems, and "fresh" akadama has more air space. As roots grow, akadama breaks down somewhat, holding more water. I've never seen better roots on my trees than those in akadama. The pad looks like a cake coming out of the pot. Earthy, porous, and easy to comb through.
If you found what works for you, great.
