Tree illness?

apham317July 24, 2012

My father noticed something weird with the tree on our lawn today and was wondering what could be going on with it, the bark has started chipping off, etc. We also believe our tree is an oak. Any and all responses would be helpful! Thanks for your time!

This is the Houseplant Forum, apham, you may wish to repost this question in the Tree Forum. That's what I would do.

Be sure to include your location, and maybe more pictures of the tree so that we can see overall condition.

Its difficult to tell much from the picture, but it looks like a mechanical injury from a mower or other equipment that may have wound wood beginning to roll over the injury, dislodging some bark in the process.

It's not clear if there is any seepage associated with the dark discolored wood toward the bottom of the wound and toward the right. If there is a wet area below the wood or it smells foul, suspect a condition called bacterial wetwood or slime flux. If confirmed, there is no treatment that will stop the progression of the malady. Given the position on the tree it's likely any disease would have occurred from a mechanical injury or damage to a root immediately below the wound.

Try the 'trees' forum for confirmation or other thoughts.

jose, I am afraid that there is no evidence of insect damage at all. We need to see more images. Physical injury is a big possibility since we can see grass growing right up to the trunk. Lawnmower and weedeater damage is common place. And such damage can very well result in disease. As a matter of fact, it's just that type of simple damage that introduces some of the worst of the tree diseases.

But....we have no evidence of anything We need more information.

I meant to add, apham, that there are some very deadly tree issues going on in Texas right it would be worthwhile for you to take some very good pictures of your tree to your local extension office for some regional assistance.
