Prized tree got broken half way through trunk, how to not make noticeable?

Question

can i super glue the broken part down? not a joke its really a prized tree

Answer 1

Rather than super glue,apply a stout piece of canvas or similar weather proof material as a tight bandage firmly around the damaged trunk,securing with tree ties avoiding cutting into the bark

Paint over the broken part with "Arbrex",which will prevent fungal infection.

Depending on the height of the damage,support with firm stakes to prevent wind rock.

If the sap bearing heart wood isn't too badly damaged, the tree has a fighting chance,especially if the head can be trimmed back to reduce water demand.
