Generally, the soil with water content higher than 1.95%~3.73%, and the content of organic matter such as nitrogen, phosphorus and potassium is obviously increased, which is beneficial to the growth of Robinia pseudoacacia.

Robinia pseudoacacia has strong drought resistance and does not require high water content. During the first 2-3 years after planting, pay attention to irrigation when the growing season is dry and high temperature to ensure survival. The future depends on the rainfall in a specific year. In a particularly dry year, Robinia pseudoacacia will also die of drought. So pay attention to irrigation at this time, and irrigation is not needed in general years. _
