Leyland Cypress Alternatives: Green Giant Arborvitae for Deer Resistance and Health

South Jersey contractor seeks 100 Leyland-type shrubs (3–8 ft). Aware of Leyland decline; wants deer-resistant, easier alternative.

Leyland Problems

Seiridium canker, Bot canker, branch dieback—widespread in Southeast. Fast growth but short-lived in many sites.

Green Giant Arborvitae (Thuja plicata 'Green Giant')

• Fast-growing, dense, conical (15–25 ft wide base)
• Zones 6–8 (–10°F to 20°F)
• Pest-resistant, no major disease issues
• Better deer resistance than Emerald Green
• Wind-resistant (Pacific NW origin)
• Small cones, minimal litter
• Light wood but structurally sound for hedges

Recommendation

Green Giant is the premier Leyland replacement. Plant 5–6 ft apart for screen. Available widely.
