My sister noticed that her dogwood tree is dripping something like water from one limb. She said the ground has been very wet underneath where it dripped for several days and if she stands under it, some drops fall on her. Is this sap? She said it is like water. It only does it from one limb and the limb doesn't appear to have been injured. She has lived there a very long time.
Dogwood Tree Sap

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.
