What is the white paint on the tree?

1. What is

The white paint on the trees is usually limestone, not paint. The ingredients are relatively simple and not very complicated. You can mix 10 parts of quicklime, 2 parts of lime sulfur, 2 parts of table salt, and 2 parts of clay, then add clean water and stir to mix. When brushing the trees, it is best to brush them twice, which will have a good effect. The effect of one time is not very obvious. The first time is after the fruit trees shed their leaves, and the second time is in early spring.

2. What is the function

1. Insecticide: The substances in lime can act as insecticides and can kill fungi and pests in the bark. It can not only kill insects, but also prevent insects, because insects like to grow in black places. If you paint it white, it can reduce the possibility of pests appearing.

2. Insulation: Winter nights are very cold, and brushing these on the tree body can help keep it warm. In addition, the temperature will rise during the day. The sudden change from cold to hot can easily cause the tree to dry out and crack. Brushing this on can also have this effect.

3. Reminder: Paint something white on the tree, which will reflect light under the sunlight and serve as a reminder for pedestrians.
