I do not recommend this book to the beginner who is just getting into Bonsai care-taking. This is more of a comprehensive book explaining how to create, shape, and nurture Bonsai trees. This book is very well written for and advanced level Bonsai owner. It goes into detail about how to start Bonsai trees, wire them, how to pick out the right environment, etc.
So if you're beginning, I think you should pass this book by at first. If, however, you have been into Bonsai trees for a while, this is the book to go with.
