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 from 10am to 2pm 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 used for several sessions.  The trees will be made available at well below their retail value, around $10 to $20.  All tools and materials will be provided.

When we have a large number of new members, this class has to be divided into two sessions, 101A and 101B. The curriculum is the same for both classes, but we ask that you stay with your assigned group as often as you can.  Each session meets monthly between January and June. The 2019 schedule will be announced in the Tree Line by Fall of 2018. Pre-registration is required, using the 101 Sign Up form under Resources/Member Services on this website. 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 less 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.  102 is an excellent opportunity for one-on-one conversation with experienced bonsai artists.  As with 101, when class size is excessively large, the 102 workshop will be split into two sessions, 102A and 102B.  Again, both sessions follow the same open structure with no pre-registration required.

Note:  There are no Mentorship classes in July, August or December.
