I have a very old dogwood tree that seems to be oozing an orange colored sap in many places. Can you tell me what this is and what I can do to help the tree? Thank you.

It is most likely sap and dogwoods tend to sap when they are stressed. What is causing it can be one of several things. It can be everything from the fact that the tree may be getting old (dogwoods typically only live 10-15 years) to a pest of some kind. I would check the tree carefully for pests, particularly in the junctions were branches meet. Also, make sure to give it some fertilizer, to help keep its health up.
