There's a school of thought which holds that a wound dressing may
simply seal in any nasties which have already floated in. I have no
opinion on that, myself; but perhaps you could simply use engineering
grease.
I was going to mention that and in addition say I was told to rub earth from
the base of the tree into the wound.
Something to do with letting "stuff wot the tree is use to" getting in and
colonising the wound before anything more harmful.
