If you’ve ever travelled by car or walked along roadsides, you may have noticed trees with their lower trunks painted white. But have you ever wondered why trees are painted white?
The practice of painting trees with white paint is not just a whimsical whim, there are several intriguing reasons behind it and its effects on trees are quite fascinating.
Typically, the white colour is visible on the lower portion of trees and the hidden reasons (or reasons) behind it are quite intriguing. While it may be challenging to ascertain the exact scientific reason, there are several benefits associated with this practice.
One significant benefit is protection against pests or diseases. Lime wash or white paint helps safeguard trees from insects or fungus, thereby increasing their lifespan. The white colour acts as a deterrent making it less attractive for pests to infest the trees.
Moreover, the use of lime wash or white paint helps protect the upper surface of the tree preventing bark from easily breaking. This protection ensures the tree’s health and longevity.
Additionally, experts at Cornell University have highlighted another benefit of using white paint on trees. They explain that the white colour helps protect the tree’s roots from damage caused by sunlight. In some countries, white paint is also used as road signs enhancing visibility along roadsides especially in areas without street lights.
Furthermore, in countries where street lights are not prevalent, white paint is used on trees along roadsides to improve visibility. When the light from vehicles falls on these painted trees, they become more visible aiding in navigation and safety.
The practice of painting trees white serves multiple purposes ranging from protection against pests and diseases to improving visibility along roadsides. While it may seem like a simple act, it has significant implications for the health and safety of trees and those who interact with them.
