Did You Know?
1. Arborvitae, also known as Thuja, can tolerate some shade, but it prefers full sun. However, excessive shade can cause the growth to become thinner and sparse.
2. The name “arborvitae” comes from Latin and translates to “tree of life.” This name was given because Native Americans once used the inner bark of arborvitae trees for medicinal purposes.
3. Arborvitae is not actually a true cedar tree. Despite its common name, it belongs to the cypress family (Cupressaceae) and is native to North America and parts of Asia.
4. One fascinating fact about arborvitae is that it contains natural oils that act as a pest repellent. This property has made the tree popular for landscaping and as a natural alternative to synthetic pesticides.
5. In addition to its medicinal and landscaping uses, arborvitae has historical significance. Native American tribes used it to build canoes and shelters, and it was also a source of traditional dyes.
Sunlight Requirements for Arborvitae Growth
Arborvitae, scientifically known as Thuja, is a popular landscaping evergreen tree cherished for its vibrant foliage, elegant conical shape, and low-maintenance nature. However, adequate sunlight is crucial for the growth and development of arborvitae trees. Sunlight is vital for photosynthesis, the process plants use to convert sunlight into energy.
To ensure healthy growth, arborvitae trees require a minimum of six hours of direct sunlight per day. Placing them in an area where they receive at least six hours of direct sunlight allows them to flourish and maintain their robust and dense foliage. Although arborvitae can tolerate some shade, insufficient sunlight can result in poor growth, thinning of the foliage, and an overall weakened appearance.
The key points to remember about arborvitae and sunlight are:
- Arborvitae is a popular landscaping evergreen tree known for its vibrant foliage and elegant shape.
- Adequate sunlight is crucial for the growth and development of arborvitae trees.
- Six hours of direct sunlight per day is the minimum requirement for healthy growth.
- Insufficient sunlight can lead to poor growth, thinning foliage, and a weakened appearance.
“Sunlight is the key to the vibrant and healthy growth of arborvitae trees. Providing at least six hours of direct sunlight per day will ensure their robust foliage and overall beauty.”
Tolerance of Arborvitae to Light Shade
While arborvitae prefers full sun, it can adapt to light shade conditions, albeit with some adjustments to its growth and development. With only four hours of midday sun per day, arborvitae can still survive and maintain its health. Light shade conditions can be created by planting arborvitae in areas that receive filtered sunlight through the canopy of surrounding trees or by providing artificial shade using a shade cloth. When arborvitae is grown in light shade, it may not grow as vigorously or develop as dense foliage as those receiving full sun, but it can still thrive with proper care and maintenance.
It is worth noting that different arborvitae species have varying levels of shade tolerance. The giant arborvitae, scientifically known as Thuja plicata, is more shade tolerant than the Eastern or American arborvitae (Thuja occidentalis). The giant arborvitae can withstand more shade and still maintain its lush green appearance. Therefore, if you have areas in your garden or landscape with partial shade, opting for the giant arborvitae variety may be the ideal choice for a thriving evergreen presence.

Shade Tolerance Comparison: Giant vs. Eastern Arborvitae
When it comes to shade tolerance, the giant arborvitae surpasses the Eastern or American arborvitae. Both varieties can adapt to light shade conditions, but the giant arborvitae has a higher tolerance for reduced sunlight. This makes it the preferred choice for landscapes with areas of low sun exposure or near taller trees that provide extended periods of shade.
On the other hand, the Eastern or American arborvitae thrives in full sun or light shade. However, its growth may be negatively affected in areas with prolonged shade. While it can tolerate some shade, it’s important to note that excessive shade can cause the Eastern arborvitae to become stressed or exhibit signs of sparse foliage, which affects its overall aesthetic appeal.
To summarize:
- The giant arborvitae has higher shade tolerance.
- The Eastern arborvitae prefers full sun or light shade.
- Extended periods of shade can negatively impact the Eastern arborvitae’s growth.
- Excessive shade can cause stress and sparse foliage in the Eastern arborvitae.
Therefore, if you have areas with reduced sunlight, the giant arborvitae would be a great choice for your landscape.
Impact of Full Shade on Arborvitae’s Density
Arborvitae loses its dense habit when grown in full shade. Full shade refers to areas where the arborvitae receives minimal direct sunlight, generally less than four hours per day. In such conditions, arborvitae trees exhibit reduced growth, weaker foliage, and may become spindly or lanky in appearance. The density of the foliage diminishes, and the overall health and vigor of the tree can be compromised.
If your landscape or garden has areas with full shade, it is recommended to consider alternative shade-tolerant plants or consider creating brighter spots by trimming or thinning out the canopy of taller trees. However, if limited options exist and you still wish to incorporate arborvitae in full shade areas, proper care and maintenance will be crucial in ensuring their survival. Extra attention should be given to watering, fertilization, and pest control to support the health and growth of the arborvitae.
Arborvitae’s Optimal Sunlight Conditions
While arborvitae can tolerate light shade with only four hours of midday sun per day, it is important to provide it with the optimal sunlight conditions for best growth. Ideally, arborvitae should be planted in an area that receives a minimum of six hours of direct sunlight per day. This will ensure that the arborvitae trees thrive, maintain their lush foliage, and contribute to an aesthetically pleasing landscape.
To achieve the optimal sunlight conditions for arborvitae growth, strategic placement of the trees is essential. Observe the sunlight patterns in your garden throughout the day to identify the areas that receive the longest and most direct exposure to the sun. Planting arborvitae in these sunlight-rich spots will provide them with the necessary energy for robust and healthy growth.
while arborvitae trees prefer full sun, they can adapt to light shade conditions with some adjustments to their growth patterns. The giant arborvitae is more shade tolerant than the Eastern or American arborvitae. However, when grown in full shade, arborvitae loses its dense habit, compromising its overall aesthetic appeal. Therefore, it is recommended to plant arborvitae in areas that receive at least six hours of direct sunlight per day for optimal growth and vitality.

Frequently Asked Questions
Which arborvitae grows best in shade?
While Eastern or American Arborvitae (Thuja occidentalis) may struggle in shady conditions, the Giant Arborvitae (Thuja plicata) has shown to be more shade tolerant according to Michael Dirr. It is worth noting, however, that Arborvitae may lose their characteristic dense habit when grown in full shade. To ensure the best growth and maintenance of these trees, it is advisable to provide them with some degree of sunlight and avoid extensive shade.
Do arborvitae grow slow?
The growth rate of arborvitae can vary depending on the species. Some species, like globe arborvitae, have a relatively slow growth rate. On the other hand, species like techny arborvitae can exhibit a much faster growth rate, reaching up to four feet per year once they have matured. Therefore, it is important to consider the specific species when determining the growth rate of arborvitae.
Will brown arborvitae turn green?
Although a brown arborvitae may not completely regain its original vitality, there is still hope for its revival. It is possible for the once brown branches to regenerate, and the parts closest to the trunk can gradually turn green again, resembling their natural color. While the arborvitae’s overall health may not fully recover, this sign of rejuvenation offers a glimmer of hope for its restoration.
Where do Arborvitae grow best?
Arborvitae trees thrive best in locations that provide full sun or partial shade. For optimal growth, it is crucial to choose a spot that receives a minimum of 6 hours of direct sunlight each day, preferably during the morning hours. These abundant rays of sunshine will fuel the arborvitae’s year-round charm and ensure its flourishing presence in your garden or landscape.
