Shaved oak tree trunks
I notice in Newell Park in St. Paul almost every tree-- oaks and ashes, mainly -- have parts of their trunks "shaved." I worry that every tree is going to die. Is this shaved characteristic a sign of disease or of treatment?
Thank you for the question. I haven't seen this so I don't know to what you are referring. Is it possible to get some photos of what you describe?
Sure, I just fell on the ground taking these pictures. I'm OK. here they are, shaved trees -- disease or treatment?
Thank you for the photos. Another Expert suggests this might be a fungal condition called smooth patch. It does not affect the tree's health. Read more about it here:
