Trees add great visual appeal and value to a property. As such, it can be concerning to suddenly notice one that has developed a hole in its trunk. This open area, referred to as a cavity, is a regular occurrence but usually isn’t problematic when handled correctly. With proper tree care, it’s possible to maintain the plant’s structural integrity and health. Below, find out more about these wounds to determine the best action to take.

Common Causes of Tree Cavities 

Cavities typically form when a tree has sustained physical injury. Often, this is the result of improper pruning. Mechanical damage is another common cause, which includes any activity that harms the plant’s roots, stems, leaves, or branches. Thus, injuries can be attributed to items like lawnmowers, trimmers, vehicles, animals, and construction equipment. 

Inclement weather can lead to cavities as well. For example, lightning strikes can rip off the bark, leaving the plant’s interior vulnerable enough for a hole to emerge inside. On the other hand, powerful winds can break branches, and rapid fluctuations in temperature could cause a tree to split open. 

What to Do About Them

In the past, removing decaying wood and filling tree cavities with materials such as concrete, expanding foam, or tar was common. However, you should avoid this practice, as it can do more damage in the long run. The filling could trap more moisture in the plant, promoting rot. There’s also the potential for healthy wood tissue to become compromised, reducing the tree’s ability to control the spread of decay.

Instead, leave the opening alone in most cases. Smaller holes often heal on their own, but if treatment is necessary, a professional tree care expert can help. They’ll use pruning methods to minimize the weight and size supported by the affected area. If it’s not possible to fix the underlying issue or the tree’s structural strength has been considerably weakened, it could need to be removed.
