What's eating my waldbrunn spruce?

Spruce spider mite (Oligonychus ununguis)

Signs: Bronzed, stippled needles and webbing; inner needles drop, leaving bare patches in the canopy.

Control: Apply horticultural oil or insecticidal soap; ensure adequate watering during summer drought periods.

Eastern spruce gall adelgid (Adelges abietis)

Signs: Small galls at new shoot bases that abort the tip growth when they open.

Control: Remove galls before they open in late spring; apply dormant oil annually in early spring.

Voles (Microtus spp.)

Signs: Gnawed bark at the base of stems at or just below ground level; tunneling in roots can girdle the plant.

Control: Place hardware cloth cylinders around the base; keep mulch pulled back from stems; use vole repellent bait stations nearby.
