Weeding cloth is generally made of PE or PP materials. "Grass proof cloth" is a shading material. After the weeds under the tree are covered with "grass proof cloth", they lose light and are difficult to carry out photosynthesis, which means they lack energy for growth. In a short period of time, they will die, achieving the purpose of weeding. Dead weeds can also become organic fertilizer and fertile soil after rotting.
At the same time, "weeding cloth" can also retain water and moisture, and to some extent, prevent and control some diseases in the soil. In this way, there is no need for manual weeding or the use of herbicides in the park, eliminating the pollution of pesticides on the environment and soil.
