Hello, pruning is usually about 45 days before germination. Grape buds are usually 3-5 buds, preferably the most full. Pruning is selected according to the thick branches. Usually, the branches leave 4-5 buds thick and 2-3 buds thin. Use the short and medium pruning method! Cut the mouth flat and leave 2-3cm above the bud! You can spray stone sulfur mixture after cutting!
