Drilled a 3/8" hole about 3" deep into the side of a maple tree - in

Turned out to be the wrong location and now the tree has that hole in
it.

What would you do to minimize the insult?

I'm thinking just sterilize a 3/8" bolt and put that into the hole.

Dont do anything, it will heal itself. That is such a small hole that
you wont even see it in a few months. If you're having winter now. you
might notice sap running out in a month or so. You could stick a short
piece of 3/8 OD steel pipe in it, (like fuel line tubing), and you might
get a gallon of sap. (Which will make very little syrup, but it could be
a fun project). Google "make maple syrup" for more info....

I think there is something toxic to a tree about copper tubing, so dont
use that. ( I might be wrong).
