Is my norway spruce dying or just stressed?
Two patterns matter here: small branch tips browning and dying back inward, which Purdue has been seeing more of in submitted samples, and Cytospora canker, which is the real killer of 10-20 year old trees. Cytospora is diagnosable on site — the lowest branches die first and it climbs, with white to bluish resin crusted on the bark at the canker; a tree that is merely thin and off-color with no resin bleeding is stressed, one with dead lower whorls and resin streaks is being dismantled limb by limb.
Why norway spruce ends up on a quote here
This is the spruce that actually works in Indiana — Purdue recommends it as the replacement when blue spruce fails, because it carries real resistance to Rhizosphaera needle cast. The catch is scale: people plant it as "a spruce" on a quarter-acre lot and end up with a seventy-foot tree eight feet off the foundation.
