Just out of curiosity why do you not think it is bonsai material?
Are they just more prone to disease or are they just picky?

That sucks they died on you, I’m going to try anyway but thanks for the heads up on that. Are they just more prone to disease or are they just picky?
I have elms and hawthorn for deciduous trees.Do you guys have maples
I'm no expert but from what I've read apparently they're just not as robust, especially if growing on their own root stock. Some folks disagree but I've killed enough of them to think there's some truth to it. I've lost more jap maples than any other plant type.
