What does the white paint on the tree do?

Painting trees with white paint can kill the germs and pests carried by trees, play a role in sterilization and pest control, and reduce the possibility of pests climbing up. Winter can play an anti-freezing role and reduce freezing damage.

The temperature is very low at night in winter; During the day, due to sunlight, the temperature rises, and the trunk is dark brown, which is easy to absorb heat. The temperature of the trunk also rises rapidly, and it is easy to freeze and crack when it is hot or cold.

Because lime is white, it can reflect 40%-70% of sunlight, so the temperature of the trunk has little difference between day and night, and it is not easy to crack. Strengthening the appearance is also one of the functions to make it look neat.

In view of the occurrence of diseases and insect pests, the evergreen trees in Sophora japonica, Ulmus pumila, Lagerstroemia indica, Albizia Albizia, Populus euphratica, Luan, Liu, Cherry Blossom and Rosaceae, as well as some trees harmed by scale insects, Cerambycidae and aphids, as well as trees susceptible to freezing injury, such as Du Ying and Michelia, can be painted emphatically, while other trees less harmed by diseases and insect pests, such as Metasequoia glyptostroboides.

Whitening height:

The uniform whitewashing height of street trees in the isolation belt is 1.2— 1.5m, while other trees are whitewashed according to the requirements of 1.2m, and the whitewashing height of the same road section and the same area is consistent, thus achieving a neat and beautiful effect.

When applying liquid, it should be dried properly, and cracks, holes and branches of bark should be brushed repeatedly to avoid brush loss, brush leakage and falling off after drying.

Do it every year after the rainy season in late autumn and early winter, and it is better to apply it again in early spring.
