Slimy gunk on Birch tree

Asked April 24, 2019, 3:18 PM EDT

Please tell me what is wrong with my Birch tree. There is a slimy substance forming below where a branch was removed last spring. And, again below that, which is running to the ground.

Carver County Minnesota birch sap

Birch leak sap from pruning wounds in the spring when sap is running just like maple trees. The running sap does not hurt the tree or affect its health.
