Trees attempt to close wounds by sealing or compartmentalizing the affected area, naturally. Tree trunk damaged by construction equipment that develops wood rolled around the edges to eventually seal the wound. Pruning cuts will develop callus tissue in the exposed tissue, resulting in wounded wood. 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. After the wound, the new wood that grows around the wound forms a protective boundary that prevents infection or decay from spreading to the new tissue. Therefore, the tree responds to the lesion by “compartmentalizing or isolating older injured tissue with the gradual growth of new, healthy tissue.”.
Compartmentalization is the process that trees use to isolate broken bark, pruned branches and even severe weather damage. As long as you have properly pruned your tree or bandaged its wounds, its natural process takes over and slowly ends its recovery. 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. There are many types of wounds on the logs and most of them heal on their own.
The good news is that a tree has the incredible ability to seal or compartmentalize most wounds. Even so, when a tree trunk is injured, the injury becomes a pathway for disease, insects and decay. This situation can be repeated many times over the life of an individual tree, so a long-term plan for tree care is essential for the continued health of your trees. These cuts should be made smooth and flat, pruning a tree at random can lead to fungal infection, insect infestation, deterioration of health and death.
Prevention is really the best measure when it comes to wounds on the roots of a tree, because there is little that can be done once serious damage has occurred. While many injuries to a tree heal on their own, any breakage on the surface of the tree can be a place where decay can begin or where bacteria, viruses or insects can enter to further damage the tree or even kill it. Although it won't directly kill the tree, overpruned shrubs and trees tend to die due to associated stress after some time. A tree ribbon is a commercial product used to wrap the tree and protect the bark from inclement weather such as winter.

After trimming or dressing a tree wound, you may be inclined to use a tree wound sealer or tree wound paint. When using a tree wound sealant for excessively large cuts or wounds, the sealant should allow the wood below to breathe and should not be applied to the tip of the cut (where the bark is), since the compartmentalization process begins immediately after the wound has occurred. Tree care experts now recommend that a broken branch be cut cleanly and then allowed to heal on its own.
Understanding how the wound response works in trees highlights another difference between the way the process works in trees and people. Usually, there are clear signs and symptoms that indicate the development of tree decay in any of these parts of the tree, and whenever you find them, the wounds should be watched and treated if practical. All wounds sustained remain inside a tree, but while they may not heal, most trees do close. But when trees are able to compartmentalize wounds and contain them with new growth, infections remain localized and do not spread to existing, undamaged or infected wood.
When it comes to caring for tree wounds, it is often better to leave trees alone when they have wounds rather than applying sealants or wound paint, as these products do not prevent tooth decay. . .
