Application is key, too. Brushing it on by hand—rather than spraying—helps ensure a thicker, even coat, especially around the base of the trunk. Most tree owners apply it once a year, usually in late fall or early winter, as part of their seasonal care routine.
While it might look unusual to some, to experienced growers, those white trunks are a clear sign of attention and care. Just as purple paint on a fence can mark private property, or orange tags may signal tree removal, a white-painted trunk means protection.
So next time you spot a row of trees with white bases, know that it’s more than just a landscaping choice. It’s a time-tested method of keeping trees healthy through the colder months—a quiet, thoughtful gesture from those who understand what it takes to nurture nature year after year.
