While your tree may appear sturdy on the outside, its internal structure could tell a whole different story. Sure, trees can live for decades. However, they commonly develop internal issues, including hollow tree trunks.
Why does this happen? Are there tree services in Williston, FL, you can turn to for help? Read on as we explore the common causes of hollow tree trunks and discuss what to do about them.

Common Causes of a Hollow Tree Trunk
Any time your tree gets damaged, it will compartmentalize and seal the damaged area. However, there are times when its internal wood will begin decaying before it can do this. When this happens, the tree often develops cavities.
Below are some of the events that could trigger such decay.
Physical Injuries
Storm damage, lawn equipment, and construction activities can all damage your tree’s bark. With the tree’s defenses compromised, various pathogens can reach its internal structure and cause decay.
Insect Infestations
Certain insects can also contribute to the formation of cavities. For instance, wood-boring beetles tunnel through the tree’s bark, eventually creating hollow sections.
Fungi and Bacteria
Fungi and bacteria are among the most common causes of a hollow tree trunk. These microorganisms break down your tree’s internal structure and cause hollow spaces to develop.
Improper Pruning
While regularly pruning your tree is vital to safeguarding its health, it is important to do so correctly. Improper pruning techniques, such as cutting too close to the trunk or leaving large stubs, prevent the tree from sealing the wounds.
This leaves behind potential entry points for pests and microorganisms, increasing the likelihood of cavities forming.
Knowing When To Remove a Hollow Tree
The presence of cavities can be concerning, especially once you learn how they can impact your tree. A hollow trunk can cause:
- Structural weaknesses
- Reduced nutrient flow
- Increased risk of disease
However, not all cavities are hazardous. In fact, your tree can adapt by strengthening the surrounding wood and redistributing the weight. Doing so allows it to remain stable years after developing a hollow tree trunk.
What should you check when looking for signs of a hollow tree trunk’s safety? It all depends on several factors, including the tree’s health and the cavity’s size and location.
For instance, if the cavity is large and near your tree’s base, it can greatly increase the chances of it falling over during the next big storm.
