How useful are these sorts of things?

www.dallasbonsai.com/tools/branch-benders-jacks.html


I have a very straight trunk that is 3/4" to 1" in diameter on some starter material that I would like to add some movement to. Would these jacks be useful or would guy wires be a better course of action (the tree is not/will not be wired into it's pot by the roots)?

Either way, I would want to wrap the trunk with raffia to mitigate scarring, correct?

Thanks in advance.

Depends...

I have one and I tried to use it to bend a straight upper part of the trunk on a white pine. It didn't work out. I couldn't bend the it as far as I wanted, and after some time I noticed it was damaging the bark of the branch - it left quite deep dents that took a year to recover after I removed it.

I'm now using the same jack on a branch on a larch, and that is working out better (of course the branch is far more flexible).

Wire would probably not work on the pine; I guess I'll need a bigger jack!

Wire would have worked on the larch - and it would have given me more possibilities to shape the branch the way I want it (but in this case, I don't need that and the jack will do fine.

So, again, it depends. They can be useful, but limited. How useful they are depends on the type of tree, the thickness of the branch and the movement you require.

What type of tree is it?

Again, that depends. In general it's a good idea though.

Thanks Auk.

It's a Paper Birch sapling that I have long term ideas for, step 1 being to get some added trunk girth. I figured it would be easiest to add some curvature to the part of the trunk I forsee keeping long term now while it'sit's still relatively pliable. At the moment it's a blank canvas.
