The method of growing walnuts consists of the following steps:
1
The sowing time of walnut is usually in spring (March or April) and fall (September or October). When sowing in the spring, the temperature gradually warms up and the soil moisture is moderate, which is conducive to seed germination and seedling growth; sowing in the fall can avoid the impact of severe winter cold on seedlings. Before sowing, the soil needs to be tilled, fertilized and covered with a thin layer of organic fertilizer to improve soil fertility and water retention capacity. When sowing, the walnut seeds are evenly sprinkled on the soil surface and then lightly covered with a layer of soil, and about 50-100 kilograms of walnut seeds need to be sown per acre of land.

The shaping and pruning of walnut tree mainly includes two kinds of thinning and dispersing shape and natural happy shape. Sparse scattered form has 5 to 7 main branches, distributed in 2 to 3 layers, the crown is large, high yield; natural happy form has 2 to 3 main branches, the crown is more lush. Pruning is usually done in summer and fall to promote side shoot growth and expand the canopy.
