The outer bark is dead. The slim flux kills micros living on bark. The
outer bark is born alive. It uses its energy quickly buying suberin.
Without energy it dies.

That would be my recommendation. The slim flux does kill bark. Also
turf. This is the thing. It's better to have one fox in the hen house
than 50 coming in. Wetwood alters the wood to a higher state of
protection. It keeps the other bad guys out. Its a niche. Proper
mulching and other treatments would be good for your tree.

There is wet wood. I would suggest two books on wetwood of trees.
Common on elms.

Wetwood - Wetwood is a term used for both a disease of wood and for the
wood, altered as a result of the disease.
Wetwood is wood infected by anaerobic bacteria mostly. See "wetwood"

Do not use drain tubes to drain wetwood.

So I should just let it alone and not try and seal it or anything?- Hide quoted text -

Based on the picture given I would say it is an American Elm. Forget
the leave the bark is the distinguishing factor.

Very different bark and growth habit

As for the old pruning cut.....Looks like you have that covered but I
would back up John and reccomend leaving it alone. You could do more
damage than harm.
