How should small wounds on trees resulting from pruning cuts be treated?

Treating small wounds on trees resulting from pruning cuts is best approached with the knowledge that trees have a natural ability to heal. When small cuts are made, tree tissue can produce callus and grow over the wound, which helps in sealing it off and preventing infection.

Option C reflects the understanding that, for minor wounds, intervention is unnecessary. The tree is capable of compartmentalizing the damage and defending itself against pathogens without the need for additional treatments like sealants or dressings. Applying sealants or dressings can actually interfere with the tree's natural healing processes and sometimes trap moisture, creating conditions conducive to rot or disease.

By leaving such wounds untreated, the tree can effectively manage and heal from pruning cuts on its own, utilizing its natural physiological mechanisms. This approach promotes overall tree health and longevity.
