Hi Deirdre, 

For this question, it would be helpful if you could submit some photos showing this symptom on your flowering plum tree. It would be best if you could submit 5 photos to me via email at <personal data hidden>. Here is a description on what 5 photos that are needed: 

1. A full overview picture showing the tree from top of the canopy to the bottom and where it is located in the landscape. 

2. A close-up front view of the main trunk of the tree showing where it is anchored in the ground.  

3. Back side view of the main trunk of the tree showing where it is anchored in the ground. 

4. & 5. Submit photos of the leaves and or other areas of the tree that are raising concern to you such as oozing, sunken or dark areas on the tree, insect damage, etc. 

If you can also provide the following plant information about the tree that would be helpful as well. 

How old is this tree? 

When was it planted? How was it planted? Did you plant it or did the garden center/nursery plant it? 

When did you first notice this issue? 

Has it been going on for a while or has it just happened? 

If you have any other questions, please contact me at the Warren County Extension Office at (270) 842-1681. 

Thanks,
