Whether you’re familiar with the concept or not, white-painted trees serve an interesting and practical purpose.
Trees are particularly vulnerable to temperature changes in winter. During the day, the sun heats the bark, causing it to expand. When temperatures drop at night, the bark quickly contracts, which can lead to cracks and damage.
To mitigate this problem, trees are often painted white during the colder months. This white paint reflects sunlight, helping to regulate the temperature of the trunk and prevent it from becoming excessively hot during the day, reducing the risk of the bark cracking and damaging the tree.
This practice helps protect trees from sun damage and ensures they remain healthy during seasonal changes.
