What's eating my weeping norway spruce?

Spruce aphid (Elatobium abietinum)

Signs: Needles yellow then drop from the inside of the canopy outward; damage peaks in late winter/early spring; severe attacks cause permanent thinning

Control: Apply insecticide (imidacloprid, bifenthrin) in autumn before temperatures drop; inspect undersides of needles from November onward; neem oil for lighter infestations

Spruce gall adelgid (Adelges abietis)

Signs: Pineapple-shaped green galls at shoot bases in spring; galls dry and persist; distorted growth tips

Control: Prune and destroy galls before adults emerge in late summer; imidacloprid soil drench or bark spray in early spring

Two-spotted spider mite

Signs: Bronze or silvery stippling on needles; fine webbing in branch crevices; worst in hot dry summers

Control: Overhead watering to reduce dusty conditions; neem oil or bifenazate miticide spray; predatory mites in protected settings

Deer / rabbit

Signs: Weeping branches browsed; bark stripped from trunk base in winter

Control: Tree guards on trunk; deer fencing or repellent sprays on lower foliage; wire mesh collar for rabbit protection
