So
@turbosaurus I would either choose to repot it or choose to prune it but I wouldn't do both at the same time And for sake of establishment I would take the whole thing apart and you can just cut the jades apart from the rest, rather than just re re-root it. The only reason I would maybe do that is if I wanted it to branch lower closer to the pot. And what you might be able to do is separate the two individuals in that pot and work on both of them
And with the wiring and pruning is not sure based on picture. Could you take a picture of it that is not backlight so I can see the structure of it better?
