Wonderfull progression.
I understand that this particular tree is well into refinement.. with graceful "naturalistic" wiring, and a wonderful pot, in my opinion. Although there is one rather straight branch in the upper left that seems to be filling some more graceful branches come along.
If I may venture a few questions:
I would imagine that this species would be amenable to "hedging" as it is sometimes used literally as hedging material.. But are there any timing nuances that would be notable for generating back buds in developing material? I.e. let it grow all season and then cut back in the fall or, let it be for the growing season, but cut back in the winter or early spring?
Also, I noticed that after the first repotting there was some browning of foliage. Was that a (lost branch)response to the repotting or a fungal issue. Just curious if it was a concern at the time and if so how it was dealt with?
Great work and thanks for sharing!
