Bing cherry trunk issue
I have a 3 year old bing cherry tree but as you can see from the picture the trunk was damaged. Last year I noticed a lot of sap spewing from this portion of the tree. Once the sap was gone I was left with this. I am looking for a suggestion as to what to do with my tree. Is there anything I can do to heal it up or is it doomed? Thank you ahead of time for reading my post.
