Tree bark is a lot like human skin, protecting trees against pests, diseases, extreme temperatures, and physical damage. But there is one key difference between the two: Bark does not heal from wounds as easily.
Does tree bark grow back after damage? Not technically, but trees do have other ways of healing the wound for self-protection. If you are concerned about a large area of missing bark on your tree, schedule tree services in Leiper’s Fork, TN.
Can Tree Bark Regenerate After Damage?
When tree bark becomes damaged, the tree can be exposed to diseases and other stressors that put its health at risk. So you may wonder whether the bark will regenerate over time and repair the damaged area.
The short answer is that no, bark will not grow back on trees. Instead, trees heal bark wounds over time by isolating the wound and sealing it with a callus.
The first stage is compartmentalization, in which the tree creates chemical and physical barriers to block bacteria and fungi from entering the wound. Then, it begins covering the exposed area with callus cells, which grow from the edge of the wound toward its center.
Throughout several growing seasons, these edges move inward until the callus completely covers the wound, effectively sealing it.
When Bark Damage May Be Too Severe To Heal Naturally
Now that you know how trees heal bark wounds over time, you may wonder whether bark damage can ever be too extensive or severe to resolve. In any of the following cases, it may be best to call a professional for assistance:
- There are several large patches of bark damage that expose the inner wood.
- You see other signs of disease or decay, such as oozing sap or soft wood.
- The bark wounds extend deep into the trunk.
In these cases, the tree may lack the resources to heal the bark wound on its own, or it may be exposed to diseases or pathogens during healing that compromise its health. Tree professionals can intervene to aid the tree’s natural healing process for a better outcome.
Depending on the size and severity of the wound, professionals might use a sharp knife to cut around the bark damage and create cleaner edges. This can prevent any jagged bark from becoming caught on nearby plants or structures and ripping further.
In some cases, professionals might connect the edges of the wound through a specialized process known as bridge grafting. Other tree care measures, such as mulching the base of the tree to help the roots retain water and nutrients, can also support the tree’s overall health.
