i think you missed the point, maybe you never saw the mirai clip i was referring to. you learn from mistakes, you dont learn by being afraid to make mistakes. nobody sets out to kill their trees, you learn by not being afraid to try things. if you buy a tree for $50 from a nursery you shouldnt be afraid to work it or try out different methods.
No I dont know what the mirai clip is.
Not being afraid to work on a tree doesnt mean you do all the things at once.
There is a difference between working on a tree and totally obliterating it to the point that it dies.
Pushing a tree over the brink of death because you did too much doesn't really teach you bonsai.
Doing too much at once will only teach you that doing too much at once kills a tree.
Don't we already know this from others experience? Do we really need to repeat that on our own? I say no.
Did you learn exactly what pushed the tree over the edge? Nope, you didnt. So the lesson was pointless.
I submit that doing things one at a time and seeing how the tree responds, lives or dies will teach you a lot more than doing 2, 3, 5 things all at the same time.
Repotting the tree and removing too many roots resulting in its death teaches you that you did too much.
The next time you repot the same species, you remove less roots and it lives so you learn that there is a limit to how many roots you can remove.
Doing one thing at at time isn't being afraid of working on a tree. It is taking an aspect and trying it out and seeing what the results are.
Bonsai is a complex topic and it involves a lot of different aspects from species to species, repotting, pruning, wiring, feeding, watering.
People have been doing bonsai for 1000s of years. I dont see why people cant learn from the lessons and mistakes that others have done in the past.
I dont agree that people have to make those same mistakes and reinvent the wheel over and over to learn.
If that is the case than places like Bonsai nut, and all the bonsai books, online videos, classes, etc are all a big waste of time and money.
There is nothing wrong with taking advice from more experienced people and learning from their mistakes.
Bonsai already has a very long learning curve as it is. There is plenty to make mistakes on along the way.
Someone once jumped off a bridge and got hurt or died.
Do I really need to go jump off said bridge (or any bridge) myself to know that I might get hurt or die?
