I know many traveling bonsai professionals, some very well! It’s a tough way to make a living!
It’s difficult to create, maintain, and improve a collection of high end trees, if you’re on the road half the time. As we all know, it takes time to “create” a high end bonsai. Even starting with good material, it takes a good 5 years or so to develop and refine it to “showable” condition. And that’s just the start! And then if you sell it, yes, you get some cash, but then, you have to replace it, and spend another 5 years on something else!
In Japan, with the apprentice system, the Master can leverage his time by training apprentices to do the grunt work so that he can work on more trees, have a bigger pipeline of work-in-progress under development. The system works because the apprentices are willing to work for virtually zero wages! I’m not sure that’s a viable system here.
Japan is also smaller, the clients are more willing to go to the Master rather than have the Master come to them.
