When a tree is injured, the injured tissue is not repaired and does not heal. Trees don't heal, they get sealed. If you notice an old wound, you will notice that it does not “heal from the inside out”, but eventually the tree covers the opening forming specialized “callous” tissue around the edges of the wound. In order to survive, trees must overcome their wounds.
But they don't technically heal their wounds, at least not in the way human and animal bodies repair, restore, or replace damaged cells or tissues. The trees are constructed in layers of cells that are joined by rigid walls in a modular and compartmentalized way. This structure dictates your response to the wound. While humans and animals can heal, trees can't.
Trees do not have the ability to replace or repair damaged tissues, but rather seal wounds by growing fresh tissue on top. This prevents further damage from insects or diseases. Trees don't heal wounds like other living organisms do, they seal them. As trees cannot replace damaged tissue, they have developed a clever way to treat life-threatening wounds.
Through a process called compartmentalization, a tree seals damaged or diseased areas by forming walls around it, which literally enclose it, allowing the tree to grow around it and flourish. A healthy tree will seal wounds faster and the same for younger trees. Trees that are planted in quality, well-drained soils, with good texture and structure and that contain adequate levels of nutrition, grow in a way that favors the healing process. Therefore, when planting trees, homeowners should be aware of the effects of site selection, soil quality, and other site factors that may affect tree growth.
Wounds of the trunk that penetrate the cortex will damage the cambium layer, a thin layer of vascular tissue, which is vital for the movement of water and nutrients. If less than 25% of the bark around the trunk has been damaged, the tree is likely to recover. When fresh wounds occur on the trunk, the injured bark should be carefully removed, leaving a healthy bark that is healthy and tight to the wood. No need for a wound dressing (tree paint).
You'll be able to see the wound closing from the edges every year as the tree grows. A tree will seal over a small cavity over time, and the new wood on the tree is stronger than anything you put in the hole. When the tree's tissue is damaged or injured, the newly discovered tissue is exposed and that's when an attack is expected. But when they heal too slowly or don't heal, the tree could have serious problems developing cavities.

However, numerous studies show that faster wound closure results in fewer health problems for the tree. As long as you have properly pruned your tree or bandaged its wounds, its natural process takes over and slowly ends its recovery. Surface roots are vital for a tree's health and longevity, as they absorb nutrients and moisture needed for growth.
However, if rot starts to appear, the prognosis for recovery is not good, and you may want to consider removing the tree sooner rather than later. Although it won't directly kill the tree, overpruned shrubs and trees tend to die due to associated stress after some time. Trees are not able to replace or repair damaged tissue, but rather try to “seal” damaged tissue from healthy and living tissue.

Find a ProfessionalMake sure you always hire an insured tree care professional, preferably an ISA-certified arborist with the experience, knowledge and equipment to provide proper tree care. These injuries are usually unintentional, such as cars, construction equipment or lawn mowers, bumps to the tree trunk or superficial roots, or improper pruning. Tree trunk damaged by construction equipment that develops wood rolled around the edges to eventually seal the wound. Adding extra soil during construction and stacking it around the trunk and on top of surface roots is one of the leading causes of tree injury.
For this reason, it is best to let the tree heal on its own by compartmentalizing the wound with layers of cells to prevent the damage from spreading. . .
