problems with my blue spruce
The blue spruce is about 30 years old and has full sun. For about 10 years or more the branches have shown more bare areas, starting from the bottom of the tree. See photo. It is very prevalent now. The top of the tree appears OK. What can I do?
When older established spruce are stressed by drought or other site conditions the trees can be susceptible to Cytospora canker, a fungal disease. Blue spruce, in general, are not really well suited for our area as they are native to climates further to the north.
