The Society offers two opportunities for instruction each month, 101 for beginners and 102 for members with some experience.  There is no charge to BSOP members for these sessions except for the cost of materials in Mentorship 101, described below. The meetings are held in the Oregon Grape Room at the Milwaukie Center, 5440 SE Kellogg Creek Drive, Milwaukie, Oregon.  Please check the Mentorship Schedule or Calendar of Events for specific dates. 

If you have questions, please contact Mentorship Chairman, Lee Cheatle (email).


Mentorship 101 is for BSOP members who have little or no experience with bonsai. The class instructor will assume you have 'no bonsai skills'. Through lecture and hands-on, we will be going over the basics of how to: apply wire, bend a branch, prepare soil, clip and grow, re-pot, fertilize and the basics of tree care. Each month we build on the skills of the previous class. 

In order for everyone to have the same quality of material to work on, 101 participants are expected to purchase the current tree, which will be made available at well below their retail value at no more than $20 per session. 'Each participant will have a tree to take home after each meeting. All tools and materials will be provided.

Each session meets monthly between January and June, usually (but not always) on the second Sunday. Check the website Calendar of Events to confirm the month’s meetings. Hours are from 10:00am to 1:00pm. Pre-registration is required, using the 101 Sign Up form under Resources/Member Services on this website. There is a limit of 20 participants at each class. If the list is full, put your name on the wait list. There are often openings when a registered person does not come. Contact Lee Cheatle (email) if you have questions.

Mentorship 102 is for BSOP members who have some idea of how to work on their trees but want to hone their skills. This is a casually structured environment, and registration is not required. In this ongoing workshop members bring in their own trees, tools and supplies, and the instructor guides them through styling decisions. This workshop provides a hands on opportunity to work, learn, ask questions and observe others solving basic bonsai challenges.

Each session begins with a brief lecture on timely topics of interest, but participants may work on any task or material they desire.  Running from 10:00am to 2:00pm on first Sunday, Mentorship 102 is an excellent opportunity for one-on-one conversation with experienced bonsai artists. 

Note:  Mentorship 101 meets from January through June. There are no Mentorship 102 classes in July, August or December.
