Why are some trees painter white?


Now we know!

Nature is constantly changing, which is one of its greatest qualities. Every season brings unique colors, bringing happiness and a sense of anticipation. From beautiful pink flowers to golden leaves, nature is awe-inspiring throughout the year.

Some trees have white trunks because people paint them, not because of the seasons. Let’s find out why.

White color protects the bark from sunscald, similar to sunburns in plants, by acting as a sunblock to prevent cracking and damage to the cambium layers, which can cause dehydration.

In case the bark splits, it becomes more vulnerable to insects, fungus, and other diseases.

This artwork is typically created in winter when the bark can be harmed by changing temperatures, ranging from cold nights to warm days.

According to Christopher Evans, a forestry and research specialist at the University of Illinois Urbana-Champaign, this painting technique is commonly used on residential trees or orchards with thin bark. The purpose of painting the trunks white is to reduce the heat absorbed during the day and minimize the risk of sunscald injury.


Version 1: Trees, especially fruit-bearing ones, become vulnerable when they are damaged by sudden thaws and freezes. Severe injury can be fatal, but applying a thick coat of latex paint or a specially formulated solution to the tree trunk can provide protection against harsh winter weather.

Painter tree trunks are easier to see, especially when they are planted close to the road. This can help avoid accidents by letting drivers know there are trees around.

Ken Fisher, assistant forester for the Boulder Parks and Recreation Department, explained that the paint dots are used to discreetly mark trees. This helps contractors identify the specific trees that need attention. Over the past 25 years, many trees have accumulated multiple paint dots, although they often go unnoticed by the public.

Forest trees are also painted to show which ones are dangerous or safe, or to mark private property.

Evans mentioned that in certain areas, trees containing nests of rare or endangered species are identified. This is particularly true for the federally endangered red-cockaded woodpecker in the Southern United States, where their tree nests are typically marked with a white paint ring.

Basically, there aren’t any hard and fast standardizations for the use of marking paint in forestry.

It can be confusing to interpret the meaning of various symbols and colors.

For instance, the letter X typically indicates that the tree needs to be chopped down, while numbers indicate a count prior to harvesting.

This is how to paint the trees properly.

Avoid using oil-based paint as it hinders the tree’s ability to breathe. Instead, opt for water-based latex paint that is diluted with one gallon of latex and four or five quarts of water. Choose paint with an organic base to prevent any harmful additives that may harm the plants.

Use a paintbrush to apply the color. If white isn’t your preference, pick a shade that you like, but steer clear of dark colors.

You only need to paint the trunks once, but if you live in an area with severe weather, you might need to repaint them every year.
