Have you ever found it puzzling to see thriving trees along the road suddenly painted white from the branches down? There’s a reason behind this practice.
The trees are painted white with the purpose of combating heat during the summer and harsh weather in winter. But why does paint help prevent negative impacts on plants, rather than using something else?
Trees painted white to combat heat in summer and harsh weather in winter.
In winter, the weather can be extremely harsh or experience fluctuating temperatures throughout the day, ranging from mild cold during the day to freezing temperatures at night. Such significant temperature swings can cause the bark to split, harming the trees in a process known as suncald. White paint will reduce the absorption of excessive heat from the sun, allowing the trees to maintain a more stable temperature.
In summer, many people are also advised to avoid wearing black clothing and instead opt for white or light colors. This is because black and other dark colors absorb sunlight more readily, causing the body to heat up faster. Similarly, by painting the tree trunks white, the warming process is slowed down, keeping the bark at temperatures similar to those during winter nights.
These measures are often applied to newly planted trees, as they are more fragile than mature trees, or to fruit-bearing trees. However, painting trees is not the only method; if you are planting a new tree, you can protect it by using suitable wrapping materials.
