Pruning is beneficial to trees. But what happens to a tree when you prune it? Unlike humans and animals, when a tree is injured, the wounded tissue does not heal. This is why bad pruning can harm the tree and possibly cause premature death.
Cut wounds on any part of the tree expose it to pests and unwanted pathogens. While trees can protect themselves from open wounds as they can evolve and protect their wounds from threats. Their ability to evolve and adapt makes them different from humans and animals who suffer from wounds and create new skin tissue to seal up the skin. And in most cases, the wound will disappear in just a short time.
Trees will act on cut wounds by producing new wood that mostly develops around the wound to cover the exposed injury. Once sealed, the tree is no longer at risk of decay or disease. This process is called compartmentalization, it is slow and may take months or even years especially if it was a major branch that was pruned.
In the pasts, tree workers use non-toxic paint on cut wounds. They believe that it could protect the tree from fungi, bacteria and bugs. They also believed that this could help in sealing the wound. However, studies say using paint to seal tree wound is not helpful. It can retard the rate of the branch while it is in the stages of compartmentalization. The paint can also trap moisture and fungal spores.
Today, technological advancement allowed arborists to practise the best tree services. They no longer use paint as sealers. Call an arborist for trees pruning service Flinders View to make sure the job gets done right.
