I think that this grower is showing us so many interesting pre-Bonsai training techniques. However, there are no explanations so I could use some help from you in what this might become in the future.
My guess for the needle juniper was that he was making a jin from a sacrifice branch that is simultaneously thickening the trunk below. I also know he likes to make air layers of sacrifice branches so for all I know these branches could become new trees once they’ve helped thicken the tree below!
Wow, what a great multi-use of the material. I hadn’t thought of that!
