1. Determine the pruning target: When pruning in winter, first determine the Kyoho grape plants that need pruning. Generally speaking, plants with good growth, complete roots and clear branches should be selected for pruning.
2. Cut off the branches that grow vertically: The main branches of Kyoho grapes should grow horizontally or nearly horizontally, so when pruning in winter, cut off the branches that grow vertically and keep the branches that grow horizontally.
3. Weakening the branches on both sides: The branches on both sides of Kyoho grape tend to grow too vigorously, which affects the fruit quality. Therefore, when pruning in winter, the branches on both sides should be weakened appropriately to make the central branches develop better.
4. Cut off diseased leaves, branches and vines: When pruning in winter, cut off diseased leaves, branches and vines on the plant in time to avoid the spread of diseases and affect the health of the whole plant.
5. Cleaning up garbage: Clean up the garbage in the tree garden in time after pruning to prevent it from becoming the source of disease transmission.
Generally speaking, the purpose of pruning Kyoho grapes in winter is to promote the healthy growth of plants, increase fruit yield and improve quality.
