Copper Wiring Techniques with a Western White Pine
Western white pine (Pinus monticola) is an excellent species for learning the art of wiring with copper because of its flexible branches and classic conifer form. Copper wire provides the strength needed to position and hold branches while they gradually set into their new shape, allowing students to create elegant movement and layered branch structure. Unlike aluminum wire, copper work requires greater precision and proper application, making it an important skill for intermediate bonsai enthusiasts.
In this workshop, participants will learn the fundamentals of selecting the correct wire gauge, applying copper wire at the proper angle, and safely bending branches without causing damage. Emphasis will be placed on creating natural branch placement, balanced design, and the refined silhouette characteristic of mature pine bonsai. Students will also learn when to wire, how long the wire should remain on the tree, and how to monitor for wire bite as the branches begin to set. By the end of the workshop, each participant will leave with a beautifully styled Western white pine and the confidence to continue developing it for years to come.
Class will take place in the greenhouse.
