branch death on spruce

Asked July 13, 2017, 5:54 PM EDT

Some of the lower branches on my 20 year old spruce have died. What is the likely cause and what should I do? It is a very beautiful tree, and I would like to save it if possible.

This is probably cytospora canker, a very common disease of mature blue spruce. Here is our information about it: http://extension.umd.edu/hgic/cytospora-canker-spruce
