Southern grapevines also need to make some preparations for winter, mainly in three aspects. The first is pruning. Start pruning in the second week after the leaves fall, and cut off branches that are infested with insects, diseases, and weak growth. The second is to pour the freezing water thoroughly and fully. The third is to carry out soil burial treatment. When the soil is slightly dry, bury the soil twice. It doesn’t need to be too thick for the first time, just cover the branches and vines. The second time, it should be buried thicker to avoid frostbite.

1. Pruning

Pruning should be carried out in the second week after the leaves fall. Cut some branches short to reduce nutrient consumption and improve its cold tolerance. At this time, pruning is mainly to cut off insect-infested, diseased and weak branches, leaving only healthy and strong branches. It is also necessary to retain suitable bud eyes to ensure better growth in the coming year. In addition, please note that pruned branches must be cleaned up promptly and cannot be placed in the orchard.

2. Watering

Complete pruning After that, you need to water it, that is, water the frozen water. Note that watering should be done 10 days before the soil is buried, not too early. The purpose of watering is two-fold. One is to ensure soil moisture and increase soil temperature to prevent the roots from freezing. Second, it can avoid drought conditions in early spring. At this time, watering should be done thoroughly and fully to ensure that the soil is saturated.

3. Bury soil

Water After watering, wait until the soil is slightly dry before burying it. The branches and vines should be removed, tied together and pressed down, and buried with soil for the first time. It doesn’t need to be too thick for the first time, just enough to cover its branches. It just needs to be completed before the second freeze. At this time, it needs to be buried deeper. The specific depth depends on the climate. The lower the temperature, the deeper it will be. It can also be covered with a layer of hay to keep out the cold. Be careful to keep away from the roots when collecting soil to avoid damaging the roots.
