I would need some help with my tree. I noticed it wasn't growing as well as the past years so I started to trim it, while doing so, I found a wire wrapped around the trunk and now the bark is growing over that wire. The previous owners had put a stick to hold the tree straight, and as far as I can see, the wire was there for that reason.
I don't know that name of the tree, but they are common, ornamental umbrella like. Small yellow flowers in the early summer.
I don't want to lose my tree!..... Thank you!
