If you do not desire imposing extra injury to your tree or vine- I highly
suggest
reading this book.
And do not use wound dressing.
Once you have read it you will be able to answer your own question.

You also would be wise to offer the tree other treatments that address their
requirements.
This book would help someone understand many treatments.

Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
Some people will buy products they do not understand and not buy books that
will give them understanding.
