Did You Know?
1. Did you know that arborvitae, also known as the “tree of life,” got its name from French explorers who believed the tree’s high vitamin C content could cure scurvy during their voyages?
2. In ancient Rome, arborvitae was highly valued for its aromatic wood and was often used to sculpt intricate furniture pieces, known as “citron tables,” which were a symbol of wealth and luxury.
3. Arborvitae trees are known to have a unique defensive mechanism against predators. When an animal tries to chew on its foliage, the tree releases an unpleasant odor, deterring the attacker from causing further harm.
4. The arborvitae is the birth tree for people born between December 24th and January 20th according to Celtic astrology. It symbolizes stability, strength, and protection.
5. Arborvitae have been used for centuries as natural remedies in traditional medicine. The Native Americans used various parts of the tree, including the leaves and bark, to create poultices to treat wounds, respiratory issues, and digestive problems.
Importance Of Pruning Arborvitae
Pruning arborvitae trees is vital for maintaining their shape and size. These evergreen trees are known for their luscious green backdrop, making them a popular option for privacy hedges. However, without proper pruning, their growth can become unruly and detract from their aesthetic appeal.
Pruning not only helps to keep the tree’s form intact but also improves its health and structure by allowing for better air circulation and light penetration. It also helps in rejuvenating growth and preventing the occurrence of diseases or pests.
When arborvitae trees are left to grow without any pruning, they can become dense and develop thick foliage towards the outer areas. This can lead to problems such as an increased risk of diseases due to poor air circulation or an underdeveloped inner structure that can result in weak branches that may break easily.
By pruning regularly, you can control their growth and ensure a healthier and more attractive tree.
- Pruning helps maintain shape and size
- Improves health and structure
- Allows better air circulation and light penetration
- Rejuvenates growth and prevents diseases or pests
- Prevents dense foliage and weak branches
Timing The First Prune
To maintain the desired shape and size of arborvitae trees, the first prune should be done in late spring after the new growth appears. This is the best time as the tree has just finished its main growth period and the new foliage has emerged. By pruning during this time, you ensure that you are not cutting off any new growth while allowing the tree to recover quickly from the pruning process.
Moreover, pruning in late spring also allows you to assess the overall health of the tree. It gives you the opportunity to remove any dead or diseased branches that may have been damaged during the winter months. Pruning during this time promotes healthy growth and ensures that the tree remains strong and vibrant throughout the growing season.
Mid-Fall Pruning For Clean-Up
In addition to the first prune in late spring, arborvitae trees also benefit from a second prune in mid-fall. This pruning is mainly for light clean-up purposes, removing any dead or dying branches that may have developed during the summer months. By pruning in mid-fall, you can tidy up the tree before winter sets in, reducing the risk of disease or pest infestation during the dormant season.
During this pruning, it is important to prioritize the removal of branches that exhibit signs of disease or damage. By promptly removing these branches, you reduce the risk of spreading infections to other areas of the tree. Additionally, a clean and well-maintained appearance in the fall will ensure that the tree is in top condition and ready for new growth in the following spring.

- Remove dead or dying branches to prevent disease or pest infestation
- Prioritize the removal of branches with signs of disease or damage
Avoid Cutting The Top
When pruning arborvitae, it is important to avoid cutting the top of the tree. The natural form of arborvitae trees is conical, with the branches extending to a pointed tip. Cutting the top of the tree disrupts this form and can result in an unnatural appearance. Moreover, it may cause the tree to produce multiple leaders or an excessive amount of side branches, which can weaken the overall structure of the tree.
Instead of cutting the top, focus on shaping the sides and maintaining the desired height and width of the tree. Regular pruning of the lower branches can also help in creating a clean and well-defined look.
- Avoid cutting the top to preserve the natural beauty and form of the arborvitae.
- Shape the sides to maintain desired height and width.
- Prune lower branches for a clean and well-defined look.
By avoiding cutting the top, you can ensure a healthy and visually appealing tree.
Optimal Trimming Time: Mid-Spring
The best time for trimming arborvitae is mid-spring. Pruning during this period allows sufficient time for the tree to recover before the intense heat of summer. It also coincides with the new growth phase, ensuring that you are not cutting off any valuable foliage. Trimming at this time promotes the healthy development of new shoots and maintains the shape and size of the tree.
During mid-spring pruning, focus on removing any dead or diseased branches first. These branches not only detract from the tree’s appearance but can also serve as entry points for pests or diseases. After removing any problematic branches, proceed to shape the tree by selectively pruning the outer growth. Keep in mind the desired height and width, and maintain a balanced and symmetrical appearance.
- Remove dead or diseased branches
- Shape the tree by selectively pruning the outer growth

Pruning For Health And Growth
Regular pruning of arborvitae trees is crucial for both their aesthetic appeal and overall health. Pruning helps in maintaining the tree’s shape, improves air circulation and light penetration, and prevents the development of dense foliage that can cause various issues. In addition, pruning helps to remove dead or diseased branches, reducing the risk of infections and promoting healthy growth.
To ensure the health and optimal growth of the tree, it is essential to prune arborvitae regularly. The recommended pruning schedule includes the first prune in late spring, a clean-up prune in mid-fall, and trimming in mid-spring. Following this schedule will help you maintain the desired shape and size of the tree. In addition, pruning not only benefits the tree itself but also enhances the overall landscape, creating an attractive and healthy environment.

- Enhances aesthetic appeal
- Improves air circulation and light penetration
- Prevents dense foliage development
- Reduces the risk of infections
- Promotes healthy growth
Frequently Asked Questions
How do you prune an arborvitae tree?
Pruning an arborvitae tree requires a careful approach to avoid causing stress to the plant. Rather than being hasty with lopping shears, it is recommended to remove dead branches only. It is important to remember that removing large sections of a live tree can be detrimental. Instead, it is advisable to aim for pruning no more than a third of the shrub per season. Consistent and gradual trimmings over time are preferable, as they promote healthier growth and prevent the need for drastic pruning all at once.
Is it OK to cut the top off arborvitae?
Although it is technically possible to cut the top off an arborvitae, it is not recommended. Topping off the tree can result in a significant alteration of its shape, causing it to lose its natural upright form and take on a boxy appearance. Thus, it is generally advised to explore alternative methods of maintaining the desired height of an arborvitae to preserve its original aesthetic appeal.
Will arborvitae grow back after turning brown?
Although arborvitae may not completely regain its previous vitality, there is hope for recovery even after turning brown. While some branches may not revive, the sections nearest to the trunk have the potential to revert back to their lush green hue. With proper care and attention, a brown arborvitae can undergo a rejuvenation process and partially restore its former beauty.
How tall do arborvitae grow?
Arborvitae trees have varying heights depending on the type and cultivar. The American arborvitae can reach impressive heights of 40-60 feet and spread up to 10-15 feet when fully grown. However, if you are looking for smaller trees, you may opt for the Techny or North Pole cultivars, which have a more modest height of around 15 feet and a width of 7 or 10 feet. Alternatively, if you prefer a compact and spherical shape, there are globe-type arborvitae trees that grow to a modest 3 to 6 feet in both height and width.
