Green Giant Arborvitae

Green Giant Arborvitae

Size:  30-50' in height and 15-18' in width.  Growth of up to 4 feet per year after 'Green Giant' roots in.

Foliage and Growth: Deep green fern-like foliage with a fast growing pyramidal shape with very little maintenance.  Very dense growth provides dense screening.  Keeps lower branches which many conifers loss over time.

Hardiness Zones: 5-8.  Some sites say 'Green Giant' is fine in zone 4.

Light Requirement: Full Sun to Part-Shade.  Fuller growth habit in full sun.

Drought Tolerance: Moderate.  Perhaps more drought tolerant than Leyland Cypress.  Some additional water in mid-summer to extend growth season is recommended.

Notes: US National Arboretum introduction.  'Green Giant' has become very popular.  Its rapid growth and resistance to pest make it an ideal screening plant.  Much more wind and ice tolerant than Leyland Cypress.  It prefers moist well-drained soil.  Deer resistant. Very widely available.  Spring fertilize to push growth.  I have heard people say that they don't get bagworms, but I have seen them infested.  The trees that had them were very root bound and stressed.
