Major Causes of Tree Holes
Large holes and other tree wounds expose sensitive tree trunk tissues and increase the risk of infection, so it’s important to identify the cause of the holes to fix them properly.
Pests
A major cause of tree holes and damage is pests, such as termites, aphids, beetles, squirrels, and woodpeckers. Pests eat away at healthy bark and bore into trees, creating both large and small holes in the trunk and branches. Insects are more common pests but small mammals can also damage trees.
Fungi
Fungal infections can also eat away at your tree, creating holes and sections of rotted wood. Fungal infections are commonly accompanied by mushrooms sprouting from the trunk and root body of the tree. Fungal infections can quickly kill trees and spread, so contact an arborist as soon as you can to manage the issue.
Old Age
Sometimes, trees start forming holes due to age and natural weathering. Old trees often start to hollow out as they age, which can actually be beneficial for their health and structural integrity. The central deadwood core will dissolve first, and the nutrients will enrich the still-living outer layers of trunk tissue.
Improper Care
Holes in your trees might also be due to improper tree management and maintenance. For example, pruning can cause large holes and tree wounds if you cut the branch too close to the trunk. Pruning too close damages tree tissue and creates wounds that can get infected with diseases and pests.
Is the Tree Hole Dangerous?
So you now know what causes large holes in tree trunks — the next question is whether the hole is a problem. Whether tree holes are dangerous depends on the number of holes and whether the tree has other symptoms of damage. For example, the presence of numerous small, regular space holes usually indicates some kind of pest infestation.
Check the area around the hole for damage. If you notice decay on the inside or the wood around the hole is cracked and dry, the hole might be infected and require treatment. If you can’t identify any signs of infection or infestation, the hole may not be cause for worry.
