What happens to trees when you prune them? Well, unlike humans and animals trees do not heal when you cut their branch and do tree pruning. When wrong tree pruning is done, this could lead them to get sick and be the cause of their untimely death.
When a tree’s branches are cut, the tree becomes exposed to pests and unwanted pathogens. But this does not mean that trees are not able to protect themselves from open wounds since they have the ability to evolved and protect their wounds from threats.
While trees do not heal, 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.
When the branches of a tree are cut, the tree will act differently by producing new wood that mostly grows around the wound to stop it from being exposed. Once the wound is sealed, the tree is no longer at risk of receiving decay or disease.
The process of sealing known as compartmentalization is slow and it may even take months or even years especially if it was a major branch that was pruned.
Arborists of the pasts used to paint these wounds with the use of non-toxic paints as they believe that it could help the tree from fungi, bacteria and bugs. They also believed that this could help in sealing the wound.
However, research has shown that it is a bad idea to paint the wound of the tree. 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.
These days, the practice of tree pruning is mostly done by tree lopping Leichhardt experts who are aware of what a major pruning can do to the health of a tree. Paint is not used anymore too. If you are thinking of having your trees pruned to make sure to discuss your plans with a trusted arborist.
