Spruce Tree Leader Dieback: Causes and Outcome

A 20+ year old spruce in NH shows brown leader (top shoot) while rest of tree looks healthy.

Diagnosis

Most likely beetle boring into the terminal shoot. The dead leader can be pruned if reachable or left to fall naturally.

Long-term Outcome

• Tree will develop a new leader from a side branch.
• Results in a slight trunk crook at transition point.
• No spread to other branches—tree survives fine.

No treatment needed beyond removing dead leader for aesthetics.
