Ok. The experimental decandling at around 11:00 isn’t going to yield you much to go by, because the technique is incorrect, and not consistently applied:
1. You don’t cut the candles in half when decandling, you remove them entirely.
2. You need remove
all of this year’s growth, or else you aren’t going to force the tree to grow again in that area, but instead you are weakening that particular branch, and the others around it will strengthen. This action will make the imbalance
worse. With pines, it’s all about establishing balance.
3. The technique of decandling is used for refinement of developed pines, not rough stock like your example. Rough stock like your example should be pruned for branch selection in the fall, needle-pulled for balance, and wired for shape. If all goes well, summer candle-cutting could begin the following spring, along with balancing techniques which you seem to understand, but do not apply.
I’m not sure I can make it much further into this video. If I do, I may comment further. Your study and passion are commendable, but the teaching is a bit premature.
Here is one of my reasonably well-balanced JBP, before, and after summer candle-cutting (for shorter internodes and needles), needle-pulling (for balance) and wiring (for shape). This has been in training for 8 years, and candle-cut for maybe 3 years.
