Arborvitae trees, also known as Thuja, can vary in size depending on the specific variety and growing conditions. Some smaller cultivars, such as the Emerald Green Arborvitae, typically reach a mature height of around 10 to 15 feet (3 to 4.5 meters) with a width of 3 to 4 feet (0.9 to 1.2 meters). These compact varieties are often used as low hedges or foundation plantings.
On the other hand, larger arborvitae varieties like the Green Giant Arborvitae can grow up to 60 feet (18 meters) tall with a spread of 12 to 20 feet (3.6 to 6 meters). These towering trees are ideal for creating a tall privacy screen or windbreak.
It’s worth noting that the growth rate of arborvitae can also vary. Some varieties, like the Green Giant, are known for their rapid growth, adding 3 to 5 feet (0.9 to 1.5 meters) per year. Others may have a slower growth rate, adding only a few inches each year.
When choosing an arborvitae variety, consider the available space in your landscape and your desired height and width. If you’re looking for a larger privacy screen, opt for a fast-growing, larger variety. However, if you have limited space or prefer a more compact hedge, choose a smaller cultivar.
It’s important to provide adequate spacing when planting arborvitae to allow for proper growth and airflow. Planting them too closely together can result in crowded, unhealthy plants. A general rule of thumb is to space arborvitae about 3 to 6 feet (0.9 to 1.8 meters) apart, depending on the variety and ultimate size.
In terms of care, arborvitae trees are relatively low-maintenance. They thrive in full sun to partial shade and prefer well-draining soil. Regular watering is important during the first year of establishment, but once established, they can tolerate some drought. Mulching around the base of the tree helps retain moisture and suppress weeds.
While arborvitae generally don’t require pruning, you may choose to shape them or remove any dead or damaged branches as needed. Pruning is best done in late winter or early spring before new growth emerges.
In my personal experience, I have planted a row of Emerald Green Arborvitae along the back of my property for added privacy. They have grown quickly and provided a beautiful green backdrop to my landscape. Additionally, I have seen impressive specimens of the Green Giant Arborvitae in parks and larger estates, creating a striking focal point and privacy screen.
To summarize, the size of arborvitae trees can vary depending on the specific variety, with smaller cultivars reaching around 10 to 15 feet tall and larger varieties growing up to 60 feet tall. Consider the available space and desired height when selecting an arborvitae variety for your landscape. Proper spacing, adequate watering, and minimal pruning will help ensure healthy growth and lush foliage.
