I have had to remove a substantial amount of rotting bark from my old

AIUI sealing severed limbs etc of trees with ?Arbrex (that tarry
paste), is now no longer advised as it encourages fungal disease under
the seal. I believe the recommended treatment now is to let them heal
naturally, but I may be wrong.



Yup. I've read that, too. Best to leave nature to her own devices.
