Hi Mother of Monsters,
sorry to hear that....
I guess all you can do is cut out the soft tissue till you see healthy tissue and let it dry.
Additionally you could dust the wound with charcoal powder and/or cinnamon powder (bacterizide/fungizide).
But another point: Why don't you just go to an Indian Grocery or supermarket and look for 'Suran'. I got some in London/Southall some years ago (but killed them due to too early potting, did not know enough about Amorphophallus in those days).
Good luck,
Bernhard.
