Thuja vs. Italian Cypress: Different Genera, Different Spacing Needs

Are Thuja and Italian Cypress the Same?

No. Both belong to the Cupressaceae family but different genera: Cupressus (cypress) and Thuja (arborvitae).

Thuja Spacing for a Hedge

• Plant 5–6 feet apart for a dense barrier.
• Mature width ~5 feet; height 20–30 feet.
• Can be trimmed to any height/width.

Planting 3 Feet Apart?

Too close. Every other tree would eventually need removal. Stick to 5-foot spacing for long-term health and appearance.
