What’s happening to the lower branches of my blue spruce?
We live in York, near the Harbor. We’ve been here four years from southern California. We are still learning about zone 6 plants and actual seasons. Our blue spruce, in the front yard looks like the lower branches, especially on the north side, are dying. Is this just the natural progression of the tree as it grows taller of some disease as a couple friends have said.
