straighten wisteria trunk

can you straiten a wisteria trunk?

Doug says - the trunk of a wisteria tree is a grafted bit of wood under the vine on top of it. So the quick answer is no.

If you're asking about the vine - and the vine is mature, the quick answer is not really. It is a twisted vine shape and that's how it grows.

If you're asking about turning a vine into a tree - the quick answer is that you can't unless you can graft the top to the tree (vines don't turn into trees by growing)

Hope that helps
