On the inside, the tree creates barriers to control the spread of fungi and other microorganisms. The tree's sap and resins plug the water and nutrient transport vessels, creating both a physical and a chemical deterrent to decay.

What Not to Do
When you need to repair tree trunk damage, the trick is to avoid interfering with its natural defense mechanisms. While trees can’t heal injuries to themselves like human beings, they do have ways of mitigating the damage. Through a process called compartmentalization, a tree can isolate damaged sections of itself with new wood growth.
Clean Up the Wound as Best You Can

How do I repair a tree trunk?
Pruning the tree is a great way to repair a damaged tree trunk. Start proper pruning by removing all the dead and broken branches from the tree. Make sure you don’t prune the healthy branch as it can add stress to the tree trunk. Pruning is important because dead and dying branches are highly vulnerable to pathogen attacks and harmful insects. Pruning helps in maintaining the health of the tree trunk so, ensure that you do it properly. Also, when you make cuts during pruning, make them smooth and clean so that the tree defends itself much more efficiently from deadly infections. Once you have pruned your tree appropriately, start taking good care of it and keep it hydrated.
