Surgery and treatment of injuries to the trunk of a tree

Surgery on a tree?

Well, yes, it is possible! When a tree is the victim of an accident, blow a mechanical shovel, face to face with a car, etc. No matter what may cause the bark to peel off the trunk or the primary branches, there is a treatment for tree trunk injuries that will decrease the long-term damage caused by accident.


Peeled bark

During relatively powerful impacts on the trunk of a tree, it often happens to see its bark and the cambium (a thin membrane which is located under the bark (Suber and Liber) and which ensures the growth in diameter of the tree. ) peel off and expose the sapwood, also called living wood because it still contains living cells.

When the bark and the cambium separate but remain taken after the tree, the space created becomes a place of choice for the accumulation of humidity and becomes a gateway for insects and diseases.



Just like humans, trees can heal wounds. Of course, their healing process is much slower than ours, but they still get there. You will notice by the time you have a tree pruned, a year or two later, you can already see the scar callus closing over the cuts. If you don’t see the scar callus after two years it’s probably because you cut the branch too close, too far from the trunk, or at the wrong angle.

As with the healing of cuts, the tree will be able to heal all the wounds made to the trunk. As long as you repair them properly, here is a procedure for repairing injuries to your tree.


The operation

It’s time to go for the scalpel! It is necessary to remove all the bark pieces during the surgery, which is detached from the tree, even if it is only a few millimeters. Must, therefore:


  • Mark out an area that encompasses the entire injury.
  • Cut the boundary of the area into a round or oval shape ideally.
  • The more round the shape of the area, the more the tree will heal quickly. It is also important not to cut too much bark for nothing and excessively enlarge the wound.
  • Once the area is well cut, it is desirable to cut the bark edges at an angle of 45 °. The angle will also help with healing.
  • During strong impacts on a tree trunk, we can see splints coming from the sapwood; it is also necessary to cut these wooden splints, which can also accumulate humidity and hide insects.


And now your tree will be able to heal as quickly as possible without accumulating moisture and risking unwanted diseases.



DO NOT cover your surgery with a “miracle” product that helps heal tree wounds. This type of product is sold touting the product’s abilities to prevent moisture and disease from seeping through the wound. Yet, applying such a product to a fresh wound helps moisture build up as it prevents the wound from breathing. These products also prevent the scar callus from forming well and slow its formation. In short, these products should be avoided because they slow down the healing of your tree and increase the risk of contracting diseases.


Finally, a good surgery on an injured trunk will certainly allow you to avoid the felling of trees a few years later. If you want tree maintenance services, contact our recommended gardening company now for a free quote.
