2026 The Art of Bonsai: March-Thurs

Repotting Conifer Trees
In this hands-on workshop, Bonsai Master Bobby Curttright will teach you the essential techniques for repotting conifers. He will cover how to safely remove a tree from its pot, properly prune the roots, explain soil mixes, and position the tree to encourage healthy growth and strong structure. The specific conifer has not been selected yet. This will be your take-home project.
You’ll also learn how repotting differs for various conifer species, how to identify when a tree is ready to be repotted, and tips for aftercare to ensure a smooth recovery. This class is ideal for beginners and intermediate enthusiasts looking to build confidence in one of the most important bonsai maintenance skills.
Due to the nature of this workshop it will be held in the Gresham Japanese Garden’s greenhouse, located behind the Kyoudou Center.
All tools, soil, and materials will be provided.
Note, Fee Increase: $40 plus $15 tree, container and other supplies. To continue offering a high-quality bonsai program and covering material costs, the Garden has made the difficult decision to increase the fee for this project-based workshop.
