Dead Branches in Center of Evergreen Bushes

Question

I have an evergreen or 2 that have this phenomena going on. Seemingly dead branches in the center and on the edges where I’ve trimmed them back with my electric hedge clippers. Is there anything that can be done to bring these back?

Answer 1

Lack of sunlight and air circulation can cause centers of shrubs to suffer die back.
These issues can cause diseases such as blights or fungus problems.

If the woody stems are bare, they will not grow back leaves.
