I wire them out a bit too. I still believe you should practice proper wiring technique any time you are wiring branches, if for no other reason than good practice leads to good results. However, I wire the first/interior 2-4” of the branches, then leave the rest unwired so they will grow and thicken up.
You can get into a rhythm of selection pruning, wiring and planting in year 1, unwiring in year 2, unrestricted growth in year 3; 3-4, and then digging it up again to repeat pruning (add a little jin/shari) and wiring. It is important to get a lot of movement in close if you want to end up with a smaller tree. I have lost years of good growing by planting trunks straight up instead of adding movement right from the base.
These Itoigawa junipers are 6 year old cuttings, and are beginning the second wiring and pruning cycle. Trunks are reaching 3” in diameter, and branches are spreading out to about 48” wide.
