What ecological conditions are needed for the growth and development of walnut trees?
Different walnut species and cultivars vary greatly in their ability to adapt to rainfall. In the distribution area of Yangbi walnut, the annual rainfall is 800-1,200 mm, while introducing early-bearing walnuts to areas with rainfall above 6,00 mm makes them prone to disease. Walnut tolerates dry air, but is relatively sensitive to soil moisture conditions; soil that is too dry or too wet is unfavorable for the growth and fruiting of walnut.
