Why Are Some Trees Painted White?

That white paint on tree trunks isn’t decorative—it protects. Winter sun can heat bark during the day, then freezing nights cause rapid contraction, leading to cracks that invite disease. The paint reflects sunlight, keeping the trunk stable and preventing damage.

Growers use a thin layer of diluted latex paint once a year. It’s a simple, quiet way to protect the tree so it stays healthy into spring.
