Recently a large branch fell off of one of our trees (a gum tree, ie hard wood). The branch is about thigh thick and parts of it would make a good garden-bed liner or similar as it is quite straight and uniformly thick. However, as it came fresh off the tree, it's obviously completely untreated.
I wonder if it is a good idea to use the branch in the garden as it is, or if this is a pest risk, especially regarding white ants (termites). If it needs to be treated can it easily be done / is it worth the effort or should I just get rid of it?
