2023 Ongoing Class Schedule

Due to the popularity of these classes and size restrictions reservations must be made in advance by calling the nursery at 818 343-4090, or emailing at least two weeks prior to the dates you want.

You can book up to 4 classes at one time. Classes are limited to 8 participants.

Classes meet on the 1st and 3rd Sunday of each month in two sessions. The morning session start at 9:30am and ends at 12 noon. The afternoon session starts at 1pm and ends at 3:30pm.

Each session is 2 1/2 hours and costs $30, including the use of tools, soil, wire etc. Students can bring their own tree or purchase one here. 

Each student will receive expert instruction on whatever seasonally appropriate techniques each tree requires. Because each student has something different there is always a variety of information being given out.

Contact the nursery or keep on eye on website or socials for info on Visiting Artist workshops with some of the finest bonsai artists in the world. We also offer monthly workshops and BYOT classes with Michael Roberts of the second Saturday of each month, see schedule on website.

We are always available for private one on one or small group sessions. Contact nursery for more details.

We can also arrange corporate team events and bonsai birthday parties, contact us to set something up.
