(I took that video to show you how I treat branches..
They can be fanned just like juniperus...
Just MAKE sure your foliage is at least fifty-ONE percent oriented "upwards"..
If you wire thuja foliage upside-down, the branch will die back until "correct foliage)
In terms of keeping vertical foliage, I'm seeing other threads (@mattspinniken, and see attached) where the fronds are wired flat or even suggested to cut vertical foliage. Were they just temporarily flattened for presentation?
