The growing environment of plum trees

Strong adaptability to the climate, as long as the soil is deep, there is a certain degree of fertility, no matter what kind of soil can be planted. High requirements for air and soil moisture, extremely intolerant of stagnant water, poor orchard drainage, often resulting in rotten roots, poor growth or prone to a variety of diseases. It is appropriate to choose places with loose soil, good soil permeability and drainage, deep soil layer and low groundwater level to build a garden.
