Oak Wilt?

Asked April 16, 2019, 11:08 AM EDT

I am looking for documentation on the dangers of Oak REMOVAL during the standard growing season. Most information that I find refers to the dangers of pruning, but not full removal of trees.

The dangers of oak removal are the same as that of pruning. The injured part of the tree (the exposed cut surface) is attractive to the vectoring beetle. If the tree is infected it can be the source for infecting others trees, or can be infected and spread the disease through root grafts. Using tree paint on the stump and pruning wounds immediately after cutting during the standard growing season can help stop the spread of this malicious disease. The following links have more detailed information:
