Answer: In the winter, the management of cultivating, weeding, pruning, and pest control are mainly carried out. The pruning period and the main tasks were performed before the walnuts were harvested until the leaves became yellow. The main task was to remove the dense branches and shading branches, retract the drooping branches, and adjust the skeleton structure of the tree. The wounds caused by trimming are smeared with a healing agent to promote healing of the wound as soon as possible. The dead branches, dead branches, diseased branches and branches were burnt and destroyed, and the source of overwintering bacteria was eliminated. You can also use a knife to remove the diseased bark and apply the “General Tree Guard†to prevent dry rot and ulcer disease. After pruning, the whole garden is sprayed with “General Tree Guard†to sterilize and prevent freezing, so that the walnut trees can safely pass winter.
