My wife and I recently went for a hike and we spotted several trees on the pathway that had been painted white at the trunk.

I thought for a moment it was a path marker but after I did a little research, I discovered there are a few other reasons why some trees in Washington State have been painted white at their trunks.


Here are a few other reasons that I discovered on bobvila.com besides just marking a trial:

Protection from the Sun:

one of the most common reasons for painting tree trunks white is to protect them from the sun. Trees can suffer from sunscald, a condition caused by the sun’s rays reflecting off snow or other bright surfaces, in the winter.

This can cause irreparable damage to the cambium layer, which is responsible for transporting nutrients and water to the rest of the tree.

By painting the trunk white, the reflective surface reflects the sunlight, lessening the risk of sunscald.

Insect and Rodent Control:

Painting tree trunks white also helps repel insects and rodents.

The white coloration makes the tree trunk less attractive to pests, making it less likely that they will make a home in the tree.

This can help prevent the spread of diseases and pests that can harm other trees in the area.


As they always say, you learn something new every day and I learned that white paint on trees does a lot more than just provide an aesthetic look for the trees in your neighborhood or hiking trail. You read more about the white paint of trees here.
