So I wired my little juniper up a month ago. I thought I was going to be able to leave the wire on for up to a year, but I was wrong. After 1 month the wire was starting to dig in pretty bad in places. I removed all of the wire and loosely re-wired some of the primary branches. I was amazed that the tree pretty much held its shape after only 1 month. Luckily the wounds are fairly unnoticeable. I will probably re-wire the trunk later on (I ran out of heavy gauge wire), but for now I am just using a bamboo skewer to add support for the little trunk.
I also pinched some of the new growth and removed a branch that was bothering me.
The tree is doing extremely well and I will post updates on it over time.
Before.
After.
