About Green Giant Arborvitae Trees

Green Giant Arborvitae Trees

The Green Giant Arborvitae (Thuja plicata x standishii 'Green Giant') is a large, fast-growing, evergreen hybrid tree prized for its use in privacy screens and windbreaks. It boasts a dense, natural pyramidal shape and maintains its rich green color throughout the winter.

Key Characteristics

Growth Rate and Size: Known for its rapid growth, it can add 3 to 5 feet in height per year under optimal conditions, eventually reaching a mature height of 40 to 60 feet and a width of 12 to 18 feet.

Shape: Has a natural pyramidal to conical shape but can be clipped into a hedge.

Foliage: The foliage consists of dense, scale-like needles in flat sprays that are dark green and fragrant when crushed.

Hardiness and Resilience: It is a hardy and adaptable plant, thriving in USDA Hardiness Zones 5 through 8. It is resistant to most pests and diseases, more deer-resistant than many other arborvitae varieties, and can withstand heavy snow and ice damage once established.

Growing Conditions: It prefers full sun to partial shade (at least six hours of sun daily) and is adaptable to a wide range of soil types, from sandy loams to heavy clays, provided they are well-drained. It does not tolerate salt spray or overly wet areas.

Maintenance: Is low-maintenance and requires little to no pruning to maintain its attractive shape.

Resistance: It is resistant to most diseases and insects, including deer damage.

Common Uses

Privacy screens: Its dense, fast growth makes it ideal for blocking views and creating a private barrier.

Windbreaks: Its ability to withstand high winds and heavy snow makes it effective for windbreaks.

Hedges: It can be easily trimmed into a dense, formal hedge.

Specimen Tree: It can also be used as a standalone accent or specimen planting due to its stately, uniform shape. The Green Giant Arborvitae is considered a low-maintenance landscaping choice, often requiring little to no pruning to maintain its attractive, natural shape.

Green Giant Arborvitae spacing depends on your goal, but a common range for a privacy screen is 4 to 6 feet apart for a dense barrier or 5 to 8 feet apart for a more open screen. For windbreaks, space them 8 to 12 feet apart to allow wind to filter through. When planting, ensure each tree is at least 6 to 8 feet from fences and structures to avoid future conflicts with their roots and branches.

Spacing For Different Purposes

• Dense privacy screen: Space trees 4 to 6 feet apart to create a quick, solid barrier.


• Standard privacy screen: Plant trees 5 to 8 feet apart. This allows for a less crowded, more natural screen over time.


• Windbreak: Use wider spacing of 8 to 12 feet apart so the wind can filter through the trees and not be completely blocked.


• Staggered rows: For a more natural-looking and effective screen, plant trees in two or more staggered rows. Space trees 6–8 feet apart within each row and stagger the rows 4–6 feet apart.


• Near fences or structures: Maintain a distance of at least 6 to 8 feet to prevent the tree's roots and branches from interfering with the structure as it grows.

Other Considerations

• Mature width: Keep in mind that Green Giant Arborvitae can reach a mature width of 12 to 15 feet, so give them ample room to reach their full potential.


• Initial growth: Trees may grow slowly in the first couple of years as they establish their root system, but their growth will accelerate once they are established.


• Maintenance: If you want a more maintained, uniform hedge, you can shear the trees to keep them smaller and denser.
