Weeping bark on Aspen #557153

Asked April 30, 2019, 2:20 PM EDT

Do You have any idea what is causing the staining on this aspen? It is a a tree purchased last year from Nicks so it isn't very old. No other tree in the yard has this. Should I take any action on this or has the tree itself gone into a protective mode.

Thanks

Good Morning ~ Thank you for contacting AskAnExpert and for including a photo of the problem.  We'll need further information in order to diagnose your tree accurately.

Would you call the "weeping" you referred to an ooze and is there an odor?  Is there a "canker" (a swollen, target-type area) and what color is the wound? Are other parts of the tree affected as well?  Another picture of the area with more detail as to the appearance of the bark and any further description you can provide would be very helpful.

Thank you
