You ever walk around Kunshan and noticed that the majority of trees around the city are covered with white paint at their base? Well, you can count on Don’s ESL Adventure to tell you why!
According to my local Chinese friend and a bit of research, the white paint is used to protect trees’ bark and prevent insect invasion...err, infestation.
When trees are exposed to periods of very strong sunlight, let's say, like during the summer, their trunks, bark, and leaves can end up with damaged spots and the splitting and cracking of their bark.
This in turn could lead to disease, fungus, rotten fruits, and an overall withering appearance.
It's actually more common in younger trees that are too underdeveloped to keep up with the changes in temperature and sunlight. Thus, many of the tree bases are painted white to help repel sunlight and prevent damage.
Additionally, the white paint is an insecticide--Calcium Hydroxide—used to thwart off insects from nestling in and on the trees. The paint prevents insects from crawling up and over the tree.
