Winter pruning time of mulberry

Generally, mulberry trees are pruned from late December to mid January of the next year. After the beginning of spring, the temperature rises gradually, the physiological activities of mulberry begin to strengthen, and the buds on the branches begin to germinate. If pruning is carried out at this time, it will cause a lot of loss of nutrients and water, resulting in the bad situation of no germination or less germination and weak buds on the upper part of the pruned branches, which greatly reduces the yield and quality of mulberry leaves. Therefore, it should not be too late to prune mulberry trees in winter

Pruning method of mulberry in winter

Special pruning tools shall be used during pruning. Do not use sickle, firewood knife and other tools to cut indiscriminately, which will cause damage to branches, bark and bud mouth, and avoid uneven cutting edges, otherwise it is not conducive to the growth of mulberry. In the pruning process of mulberry trees in winter, we should select and leave enough growing branches and cut off useless branches. The length of the remaining branches is suitable to leave about 10-15cm long cutting strips at the cutting opening. Different treatments are needed for different types of mulberry trees. If it is "chicken nest mulberry", it is necessary to retain strong branches and cut off diseased branches, residual branches, weak branches, etc; If it is a "cluster branch", the weak should be removed and the strong should be retained to ensure the growth of lateral branches, so as to maintain the reasonable distribution and uniform development of branches and give full play to the group advantage

Maintenance of mulberry trees after pruning in winter

Strengthen the management of mulberry garden after winter cutting, completely remove the weeds under the tree, loosen the nearby soil, and eliminate overwintering pests and insect eggs. For mulberry trees that have not been applied with base fertilizer before pruning, it is necessary to apply enough organic fertilizer after winter pruning, and at the same time, apply an appropriate amount of phosphorus fertilizer to supplement its nutrients, which can enhance the stress resistance of mulberry trees< span>
