If you notice a large hole in the trunk of one of your trees, the cavity likely isn’t part of the plant’s natural growth pattern. So, what causes them in the first place?
As a top provider of tree services in Healdsburg, CA, Empire Tree Experts has ample experience dealing with this type of tree damage. Here, we explain the factors that lead to large openings in tree trunks and what you can do about them.
Common Reasons for Large Holes in Tree Trunks
Cavities in trunks can occur slowly over time, or they can appear seemingly out of nowhere, due to the following reasons:
- Termites: Termites are notorious wood-boring insects that can create holes approximately 1/8 of an inch wide. However, you may see larger holes connected to smaller ones in an infested tree.
- Woodpeckers: These birds use their beaks to chip at tree bark in search of insects. They often create multiple holes in one tree, which can weaken it over time.
- Fungal rot: A tree with a fungal disease may have rotting inner wood, leading to structural weakness. Holes may form in the trunk, but you may also notice conks, mushrooms, and other signs of fungal infection.
- Wildlife nesting: Birds, squirrels, and other wildlife often nest in trees. They usually take advantage of existing hollows, but their constant activity can widen them.
- Cracks or splits: Some property owners mistake trunk cracks for holes. A crack is a major structural risk that worsens in windy conditions.
- Weather: If a storm causes branches to break from your tree at the trunk, the damage can lead to cavities.
There isn’t a single answer for what causes large holes in tree trunks. If you’re unsure about the structural integrity of your tree or the causes of its cavities, schedule an arborist inspection.
When Should You Worry About Holes in Your Tree’s Trunk?
Knowing how pests and diseases cause holes in tree trunks, along with damage from weather, is important. However, you should also understand that not every hole is cause for concern.
The cause of a cavity helps determine whether the tree can heal on its own. Minor trauma that causes a small void may not affect the tree’s overall health and structural integrity.
However, a wood-boring insect infestation can put a tree at risk. In this case, the holes are a symptom of an underlying issue that needs immediate attention.
Scheduling inspections with a tree care company is helpful. These professionals can assess a trunk’s strength and recommend treatments to resolve any problems they diagnose.
