Crataegus Bonsai Seasonals

The Crataegus Bonsai Seasonals are split into two interconnecting education tools: Our online courses, the Seasonal-lites, and our in-person intensives, the Seasonals.


Taught annually, these online, half-day, teacher-led courses cover the broadest range of bonsai topics.

Testimonials from the Seasonal-lite constellation of courses:

“Really nice capsule, crash course with a lot to think about!”—Laurel 

“This was a great course. I haven’t taken his regular ‘live’ class, but the amount and quality of information was unsurpassed.”—Erich

“The virtual workshop was…packed with timely and insightful information that empowered me to be more confident in caring for my trees…The slides, video, and presentation were excellent and engaging, and the ongoing questions and interaction extremely helpful. The one-on-one session was a great bonus.”—Joyce

For thirteen years the 3-day, intensive Seasonals have offered hands-on training in traditional bonsai techniques, along, of course, with some inevitable experimentation…

Testimonials from the Seasonal-lite constellation of courses:

“I learned more in 3 days than I had in the last 12 years. He was a fantastic teacher, artist, and host while there. There were 3 others there and all had been students before me. Michael has had a large influence on where I want to go with bonsai design… I would not hesitate in recommending anyone to attend his small group sessions. Thank you Michael!!!”—Ray

“Having the opportunity to work on such beautiful material provided an experience to learn by doing and for me that replaces 100’s of lectures. I don’t believe any three days has had such a profound reawakening of my soul as to the depth and love of my trees and their lovely companion plants.”—Randi

“The Seasonals provide a remarkable combination of the three aspects essential to successful bonsai –art, science and downright fun. Having the eye of an artist and the soul of a poet, Michael has a deep respect for, and ability to see, the essential spirit of a tree both in the present and in the future.”—Howard
