Painting the lower part of tree trunks white is a practical protection method, not decoration. The coating reflects sunlight, helping prevent sunscald — a condition where daytime warming and nighttime freezing cause bark to crack. This is especially important for young and fruit trees that are sensitive to temperature swings. The mixture can also discourage insects and fungi from settling in the bark, reducing pest damage without heavy chemicals. In roadside or farm areas, white trunks improve nighttime visibility and can deter animals from chewing the bark. Overall, it’s a simple, low-cost way to protect tree health and extend lifespan.
