There are two main diseases of Bauhinia, one is angular spot disease, the other is soot disease.
When Bauhinia is infected with Cercospora, there will be some polygonal spots on the leaves of Bauhinia. In the later stage, the leaves of Bauhinia will gradually wither and fall, affecting the growth of Bauhinia. When Bauhinia is infected with soot disease, there will be many oil coal like things on its leaves, and its branches will also be black. When the disease is serious, it will affect the flowering of Bauhinia, and even gradually lead to the death of Bauhinia.
In order to prevent the disease of Bauhinia, we should regularly remove the leaves of Bauhinia every autumn, because the leaves are likely to contain bacteria. On the other hand, after the leaves are piled up and fermented, it is easy to form bacterial infection. We'd better clean up and burn the fallen leaves of Bauhinia.
If Bauhinia has been infected with the disease, we should remove the infected branches and leaves in time, and then spray the relevant chemicals in time.
There are three insect pests of Bauhinia, i.e. big coir moth, brown edge green thorn moth and aphid. These pests will eat the young leaves, tender roots and buds of Bauhinia, which will not only affect the beauty, but also affect the growth status of Bauhinia. Therefore, we should pay attention to whether there are any pests around the plant during the maintenance of Bauhinia.
In autumn and winter, we can observe whether there are insect eggs on Bauhinia trees. If there are overwintering insect eggs, they must be removed in time, and consciously retain some natural enemies of pests, such as parasitic wasps and flies. The eggs of the green moth usually live in the land for winter, so we need to dig the land around Bauhinia to see if there are any eggs. If we find that Bauhinia is infested, we can use insecticides to kill pests.
