1、 Pruning method

1. Bud retention: in spring, about 70-80% of the winter buds on the mother branch will germinate, and bud retention is required at this time. Generally, the buds with poor growth will be cut off. You can't leave too many or too few buds. Too many will consume more nutrients, and too few will fall flowers

2. Wiping buds: usually, there are many bud points Germinating on the mother branch, and the interval between each bud point is 15-20 cm. Each mother branch only needs to keep 2-5 new points, and the rest should be wiped out

3. Pinching: before flowering, keep the position of five leaves on the flower spike for pinching, and keep eight leaves for pinching if there is no flower. In addition, the vine should be tied according to the growth of the vine

2、 Pruning time

Generally, spring pruning should be carried out from March to April as far as possible. Pruning at this time will not only help its growth, but also ensure better fruit setting. The time should not be too late or too late
