ANSWER: Toni:

There may be a boring type insect present in the trunk area.  Can you send a photo?  Try taking a picture of the bottom where you see the wood.  Also, send a photo of the entire bush. A photo can be helpful in my answer.

Answer
Toni:

You may be able to get some information from your local nursery or garden center.  You might carry a sample to them to show them.  These folks have usually seen a lot of different stuff and may be able to ID.  

Getting an appropriate insecticide to the borer that is inside the wood can be a challenge.  There are a few systemics that the plant takes up through the roots.  One example is imidacloprid, which is the active ingredient in several insecticides.
