Q.Weeping White Spruce Is Going Bald In A Few Areas.
I have a weeping, white spruce that’s about six or seven years old and about eight foot tall now. Over the years it has been slowly losing needles after they go brown and it’s going bald in areas. This was a reputable nursery where I purchased it and I took care to plant it myself in well drained soil. I mulch around the base every year and keep it watered here in South Jersey. Does this have a fungus or anything you may be aware of?

This appears to be Cytospora Canker disease. This disease is best managed rather than treated. Removal of infected material, or removing the tree, completely.
