We did. We also covered it in the previous 14 page soil war. And the one before that. And the one before that...
The beat goes on. The latest wunderkind comes along and says "you can't grow good trees in turface" (or haydite or whatever other non-Boon mix ingredient is being discussed), meanwhile people continue to grow good trees in those ingredients. But Michael Hagedorn said it can't be done, so those trees must not exist I guess. It's kind of like how you can't grow junipers indoors...except for the fact that Jack Wikle does it.
The particle size of turface is on the small side, and I suspect that if it were a bit larger it would be one of the best soil components out there. You can certainly compensate for that, as evidenced by those who have been using it successfully for decades...longer than Michael Hagedorn has been doing bonsai.
Why throw the blame just onto Michael? Perhaps it's because he's the only full time bonsai professional that shares what he's doing freely on his website. Boon posts a lot on Facebook, too!
You really should include Boon, Matt Reel, Peter Tea, Ryan Neil, Bjorn, and others into the mix too. Just because they don't have blogs stating their soil mixes, doesn't mean that Micahel is a lone wolf. He just happens to be the one with a blog sharing this stuff.
Look, use whatever soil you want, I really don't care. I'm going to stick with what I know to be the most beneficial for my goals of having really great bonsai.
With that, I am done posting on this soil war.
