Gardeners and landscapers often face the challenge of selecting plants that not only enhance the beauty of their property but also survive local wildlife. Deer can be particularly troublesome, feeding on ornamental trees and shrubs and damaging carefully planned landscapes. One popular solution for both aesthetic appeal and wildlife resistance is the Green Giant Arborvitae. Known for its dense foliage, rapid growth, and natural resistance to deer, this evergreen tree has become a favorite for creating privacy screens, windbreaks, and hedges. Understanding why Green Giant Arborvitae is deer resistant, how to care for it, and where to plant it can help gardeners make informed decisions for a low-maintenance, attractive, and resilient landscape.
What Is Green Giant Arborvitae?
Green Giant Arborvitae, scientifically known as Thuja standishii x plicata Green Giant,’ is a hybrid conifer that combines desirable traits from its parent species. It is a fast-growing evergreen tree that can reach impressive heights of 50 to 60 feet with a spread of 12 to 20 feet at maturity. Unlike other arborvitae varieties, Green Giant is known for its robust health and resistance to common pests and diseases, which makes it a practical choice for homeowners who want a low-maintenance tree that thrives in various soil types and climates.
Physical Characteristics
- FoliageThe tree features lush, dark green needles that remain vibrant throughout the year. Its dense foliage creates a natural privacy screen when planted in rows.
- Growth RateGreen Giant Arborvitae grows quickly, often reaching 3 to 5 feet per year under optimal conditions, making it ideal for fast landscape solutions.
- FormThis evergreen has a pyramidal shape that gradually narrows toward the top, giving it a classic, elegant appearance suitable for formal and informal gardens.
Why Green Giant Arborvitae Is Deer Resistant
Deer resistance in plants is a highly sought trait, especially in suburban and rural areas where deer populations are significant. Green Giant Arborvitae is naturally deer resistant due to its aromatic foliage and slightly bitter taste, which makes it unappealing to these animals. While no plant is completely deer-proof, the likelihood of deer feeding on Green Giant is much lower compared to more palatable shrubs and trees. This makes it a reliable choice for landscapes that are frequently visited by wildlife.
Factors Contributing to Deer Resistance
- Texture and ScentThe soft, scaled foliage of Green Giant Arborvitae has a fragrance that deer generally avoid.
- Rapid GrowthBecause it grows quickly, any minor browsing by deer does not significantly affect the overall health and appearance of the tree.
- Dense FoliageThe thick, overlapping branches make it difficult for deer to reach the inner parts of the tree, further reducing damage.
Planting Green Giant Arborvitae
Proper planting is crucial to maximize the benefits of Green Giant Arborvitae, including its deer-resistant properties. Choosing the right location, preparing the soil, and following correct spacing guidelines ensures healthy growth and long-term success.
Ideal Growing Conditions
- SunlightGreen Giant Arborvitae thrives in full sun to partial shade. Full sun promotes dense foliage and rapid growth.
- SoilIt adapts well to a wide range of soil types, including clay, loam, and sandy soils, but prefers well-drained soil to prevent root rot.
- WateringRegular watering is essential during the first few years after planting, especially in hot or dry climates. Once established, it is moderately drought tolerant.
Spacing and Arrangement
When using Green Giant Arborvitae as a privacy screen or hedge, spacing is critical to allow each tree enough room to grow without crowding. Typically, trees should be planted 5 to 6 feet apart. Planting too close can lead to competition for sunlight and nutrients, potentially reducing the overall health and appearance of the hedge. For natural windbreaks or stand-alone trees, spacing can be greater depending on the size of the property and desired effect.
Care and Maintenance
Green Giant Arborvitae is known for its low-maintenance requirements, but some care is needed to ensure optimal growth and longevity. Proper maintenance helps retain its deer-resistant qualities and overall health.
Watering and Fertilization
- Water newly planted trees deeply once or twice a week during the first year.
- Apply a balanced, slow-release fertilizer in early spring to encourage healthy growth.
- Mulching around the base helps retain moisture, regulate soil temperature, and reduce weeds.
Pruning
Pruning is generally minimal for Green Giant Arborvitae. Light trimming can maintain a neat shape, especially when forming a formal hedge. Avoid heavy pruning into old wood, as new growth may not emerge from the center of older branches.
Pest and Disease Resistance
While Green Giant Arborvitae is naturally resistant to many pests and diseases that affect other arborvitae varieties, occasional issues like bagworms or spider mites can occur. Monitoring for signs of infestation and treating early ensures that the tree remains healthy and continues to deter deer effectively.
Uses in Landscaping
Green Giant Arborvitae is highly versatile in landscaping projects, making it a preferred choice for many homeowners and designers.
Privacy Screens and Hedges
Its dense foliage and rapid growth make it ideal for creating a natural privacy screen or hedge along property lines. Planting in rows can block unwanted views and reduce noise from nearby streets, providing both aesthetic and functional benefits.
Windbreaks
Due to its height and density, Green Giant Arborvitae is effective as a windbreak, protecting gardens, patios, and homes from strong winds. Rows of these trees can reduce soil erosion and create microclimates for other plants in the landscape.
Specimen Trees
For larger properties, a single Green Giant Arborvitae can serve as a striking focal point. Its pyramidal form and vibrant green foliage add year-round interest to gardens, parks, and commercial landscapes.
Green Giant Arborvitae stands out as a practical and beautiful choice for gardeners who want an evergreen that is both visually appealing and naturally deer resistant. Its rapid growth, dense foliage, adaptability, and minimal maintenance requirements make it an ideal option for privacy screens, hedges, and windbreaks. While no plant is completely immune to deer, the aromatic foliage and resilient nature of Green Giant Arborvitae significantly reduce the risk of browsing damage. With proper planting, care, and attention, this evergreen tree can provide long-term value and beauty to landscapes, ensuring a durable, attractive, and wildlife-resistant garden solution for years to come.
