Can the incision of Lagerstroemia indica trunk be bandaged?

After the tree is sawed, it needs to be disinfected first, because there will still be juice on the surface of the wound.

If it is not disinfected, it is easy to breed all kinds of germs. Trees heal much slower than germs. After disinfection, you can apply plant ash to its wound, or buy a protective agent to apply it. Some wounds will take years to heal.
