Trees with white-painted trunks aren’t decorative—it’s protection.
In winter, dark bark absorbs sunlight, warming up during the day. When temperatures suddenly drop at night, the tissue freezes and cracks—a condition called sunscald.
White paint reflects sunlight, keeping the trunk temperature stable and preventing damage.
Gardeners use diluted water-based paint so the tree can still “breathe,” and it may also help deter pests.
In short: that white coating helps trees survive winter and stay healthy. 🌳
