Cutting the top off of an arborvitae is not a recommended method for maintaining the desired height of the tree. While it is technically possible to do so, it can have significant negative consequences for the tree’s overall form and appearance.
When you top off an arborvitae, you essentially remove the uppermost portion of the tree’s main leader or central stem. This results in a loss of the tree’s natural upright shape and can cause it to become more boxy-looking. The tree’s growth pattern will be altered, and it may develop multiple leaders or branches that grow in various directions, rather than maintaining a single, dominant leader.
Furthermore, topping off an arborvitae can lead to an increased risk of disease and pest infestations. The open wounds created by the pruning cuts provide entry points for pathogens and insects, which can harm the tree’s health. Additionally, the tree may respond to the pruning by producing excessive new growth, which can be weak and prone to damage.
In my personal experience as a gardening and landscaping expert, I have seen instances where arborvitae trees have been topped off, and the results were not favorable. The trees lost their natural beauty and symmetry, and their overall appearance was significantly compromised. It is important to consider alternative methods of tree maintenance, such as selective pruning or trimming, which can help maintain the desired height while preserving the tree’s form and health.
To summarize, cutting the top off of an arborvitae is not recommended as it can drastically change the tree’s form, making it appear more boxy and less upright. It can also increase the risk of disease and pest issues and lead to weak, excessive growth. It is best to explore alternative methods of tree maintenance that preserve the tree’s natural beauty and health.
