Maple tree bark looks wet

Asked February 10, 2019, 3:47 PM EST

The bark of my Autumn Blaze Maple tree looks wet. From the top of the tree all the way down it's entire length, the tree is leaking sap. There doesn't appear to be any damage to the tree and there are no broken branches. The bark is splitting in some locations. Also, we didn't prune the tree in the last year, so it isn't coming from late pruning. Should I be worried about disease?

Thank you for your question. I suspect the issue may be Bacterial Wetwood. See link below - provides details on this issue. I suggest your compare the symptoms of your tree to the symptoms described in the link and try to confirm that Bacterial Wetwood is the problem.
