Tree Wound Painting: What It Is, And Why It's Dangerous
If you have a few trees on your property, then you have probably been advised by a well-meaning friend or neighbor to paint their wounds after trimming or pruning them. Unfortunately, not all well-meaning advice is useful; in fact, tree wound painting may even be dangerous for your trees.
The Background
When you cut a tree branch, you expose the inner tissues of the tree to the outside environment. This can lead to various health issues for the tree; for example, the tissue exposure increases the risk of attack by microorganisms as well as the risk of weather-related damage.
