I just bought a Five Needle Pine at a bonsai nursery and i noticed that some of the wires are going into the bark and wondering what I should do? The guy who sold it to me said the trunk has lines which look like scar marks because steel wire was used on the trunk to thicken in which makes me thing they maybe they are trying to thicken the top of the tree?
Attached are some images.
Wire scars are just part of bonsai.
@Sugartree, the way your tree was produced is the lower part is JBP, and the upper part is JWP. (Five Needle Pine). They wrap wire around the JBP, give it a bend or two, then plant it in the ground for a decade. The JBP grows over the wire giving it an "aged" appearance. This was all done intensional.
The JWP part, with the smooth bark, will scar if the wire is left on too long. It looks like it is beginning to cut in. You can remove it if you like.
The best way is to unwind the wire. This way it is lifted straight up out of the groove it made. If you try to cut it out in chunks, if it's grown in, you damage the tree even more because you have to cut into the wood to cut the wire. Most people do it wrong, buy cutting in chunks. Much better to do it the way the pros do: unwind it!
Very large wire can be cut in chunks. But spin off as much as you can. Gripping the wire with pliers is the easiest way.
