What's eating my atlantic white cedar?

Atlantic White Cedar faces the cypress aphid and juniper scale as primary insect threats. Bagworms are destructive across its range in the eastern US. It is highly susceptible to Phytophthora root rot in poorly drained sites. White-tailed deer heavily browse this species in coastal areas. Beaver damage can destroy entire stands in wetland settings.

Caterpillars build spindle-shaped silk-and-foliage bags on branches; feeding strips foliage; uncontrolled infestations can defoliate and kill trees — Atlantic White Cedar regenerates poorly after complete defoliation Hand-remove bags in winter; spray Btk or spinosad at larval hatch in late May–June; bifenthrin for severe infestations; monitor annually as populations can build rapidly

White-grey armoured scales on foliage and branches cause yellowing, foliage thinning, and gradual dieback; sooty mold from scale excretions can further reduce photosynthesis Apply horticultural oil at crawler emergence in late spring; systemic imidacloprid for established infestations; prune out heavily scaled wood; avoid excess nitrogen that stimulates soft growth scales prefer

White-tailed deer browse foliage from the lower 4–5 feet, leaving a clean browse line; heavy pressure in coastal pine-barrens and wetland edge habitats can prevent natural regeneration entirely Wire tree cages or tubes for seedlings and saplings; tall perimeter fencing for restorations; repellent sprays in winter and early spring; plant in larger cohorts where browsing pressure limits individual attention
