Each meeting features a different topic with expert instruction. Programs range from hands-on workshops (air-layering, repotting, deadwood carving) to guest artist demonstrations to group critiques and “bring your own tree” sessions. Three meetings per year feature our Artist in Residence, Sergio Cuan. Demo trees are often raffled to attendees at the meeting's conclusion.
