I would not remove it from the can now, as you've obviously pruned and wired, not the best time to wire at that.
Further insult to the project could lead to its demise, certainly would weaken it. Just feed it. Do NOT remove wire.
Sure the roots can be re-exposed later, they can also be left as is.
I guess the question is, how exposed were these roots prior to this current state?
If they were covered well, nice to know they're there, and recover.
The more these junipers are allowed to grow out, the faster they will marry.
Make that 3 that I bought this year. Forgot about this Gold Lace, so let me explain what I was saying in my last post.
The branches left to grow, thicken and become rigid. Seconday branches become less wimpy, but the new growth beyond
still, is fine and wimpy. I'm doubting the new foliage will ever be anything but wimpy, but getting the new foliage to be
more close in is what I'm trying to accomplish here. Older darker green inner foliage and thicker branches now more close to the new foliage
should help support the new, more golden growth, I think.
So next from here I feed normal the rest of this year. Very little if any maintenance pruning and pinching.
Next Spring, I will remove at least 50% of the nursery soil probably more, and repot.
When it recovers from that, and gets leggy with bushy growth, I will cut back again, probably still no wire, maybe some that Fall,
depends on vigour.
