Interesting concept...No it's just that you don't have any idea what you're reading...They are fine after they have been root pruned a number of times. ....as I said. But maybe because you buy your trees already developed you can't imagine what it's like starting from scratch like us poor people.
I purchased both my Atlas Cedars from Jim Gremel. Jim is a student of Boon, as am I. We both repot our trees using the same soil, and same technique. Now, it’s true that Jim grew both these trees in the ground to develop them, and then “collected” them, and put them in bonsai pots. I wasn’t there, but I’m pretty sure he would have done it as Boon teaches. I’ve been to Jim’s home and seen how he operates.
But, hey, I’m not omniscient like you are Michael.
