Considering this, why are my spruce trees dying?

When entire lower branches on a spruce have died, the problem is more likely to be cytospora canker, Yiesla said.

Why are my spruce trees turning brown?

Spruces can suffer from Rhizosphaera Needle Cast, a fungal disease that causes needles on spruce trees to turn brown and drop, leaving bare branches. It usually starts near the base of the tree and works its way up. You can check for this fungus by looking at the needles with a magnifying glass.
