Praise for Bonsai Heresy

“Bonsai Heresy…is an articulate, balanced, researched, captivating — and sometimes witty — discussion of bonsai topics covering everything from techniques, to supplies, to aesthetics. So thoughtful and well written, I couldn’t put it down…I’m sure that I’ll be going back to reread portions as various situations arise. I highly and enthusiastically recommend the book!!!”  —C. Brown

“This book is long overdue and certain to be a classic! If you’re serious about bonsai, you must read this book!”  —Joe T.

“I agree with the previous reviews that this is the best book, to date, on why we should and how we can cultivate bonsai. So I won’t repeat the superlatives, but will offer other reasons for reading Bonsai Heresy. Michael Hagedorn is a quiet philosopher, devoted horticulturist, insightful artist, and crafty wordsmith. He has an uncanny ability to describe the mystery, science and satisfaction of knowing what to do with trees in pots. He also, and this is just as valuable, suggests an aesthetic of bonsai that will deepen our enjoyment of this living art.”  —Ron D.


Post-Dated: The Schooling of an Irreverent Bonsai Monk — $14.95   The whimsical story of Michael Hagedorn’s apprenticeship in Japan (Spanish and Portuguese editions available soon)

Praise for Post-Dated

“An illuminating book for those seeking the true meaning of bonsai…revealing how bonsai opens our hearts to compassion and the poignant beauty of nature.”  —Felix Laughlin, Past President, National Bonsai Foundation

“… Michael’s thoughts and experiences are accurate, informative and well written. I was captivated by his book and could not put it down until I finished it!”   —William N. Valavanis, teacher and publisher, International Bonsai magazine

“Michael’s [book] can spread the messages that I have always wanted to express most through bonsai . . . love for the mercy of all living things in the world, and peace: people’s hopes and dreams manifested through true works of bonsai, which can go far beyond human vitality.”  —Shinji Suzuki, Kokufu and Prime Minister Award-winning bonsai master

Sharpen up your bonsai. 

Much of what I offer caters to those fully invested in the bonsai hobby. But bonsai is not just for those wanting to study it, or looking to hire a professional. Bonsai is for everyone. If you wish to experience bonsai, I invite you to contact me for a garden visit.

Styling and Refinement


In Japan, a bonsai professional is considered to be one who styles and maintains trees owned by clients. This was my training, and it remains one of the most rewarding of my services in the United States. It was a great honor to work on some of the best trees in the world while an apprentice in Japan, and it is a goal of mine to see the bonsai here reach that same high level.

Along with sharing by teaching, creating and maintaining bonsai gives me great joy. I frequently have bonsai dropped off at my studio for styling, rewiring, or detailing for an upcoming show. I also work on private collections on site.


The bonsai yard is offered as a no-fee sanctuary for those who have experienced recent loss or trauma and wish to be around trees. Some light bonsai activities are available on request.
