Protection of Sophora japonica
Also known as Sophora japonica, Sophora japonica is a street tree and an excellent nectar source plant. Planting Sophora japonica requires sufficient soil nutrients and good air permeability. Sophora japonica is a typical light-loving plant, which can be placed in a semi-cloudy and semi-sunny place during the growing season. When the sun is too strong, shade in winter and give full sunshine. Fertilization should be as far away from the roots as possible, and it is best to use fertilizers with high nitrogen content. You can properly water the basin in the peak season and always keep the soil slightly dry.
Pay attention to pruning at ordinary times, and pruning in summer is to make it have more side branches, make it more lush, and at the same time, it can inhibit the growth from being too high. Winter pruning is to prune the weak branches and leaves eroded by pests and diseases, and then carry out plastic surgery.
