sick oak tree #758819

Asked June 28, 2021, 12:44 PM EDT

Hello, One of our oak trees lost a big branch. There are 3 pictures attached. Picture "oak 1 " shows the branch in the ground , picture "Oak 2 " shows the hole left in the tree, picture "Oak 3 " shows in detail the affected area . What should we do ? Is there anything that could be done to save the tree? Should we remove the whole tree? or just the affected branch ? Thanks in advance Berta Warman <personal data hidden>

Hi,

That’s a pretty serious wound to your oak that happened at a bad time (April through August is when the fungus that causes oak wilt is most rampant). 
You can try and paint the wound with latex house paint to protect from the fungus.

If it’s an important tree to you, I would have a certified arborist come take a look: https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional

Thank you for your inquiry and good luck! Replied June 28, 2021, 3:16 PM EDT
