It needs to be pruned in time when it blooms. Before flowering, new branches and vines should be pinched to about 10 centimeters. The tendrils should also be cut off during the growth period to save nutrients. When flowering, remove excess fruit ears in time, leaving only one inflorescence on each fruiting branch. 10 days before flowering, cut off all the side vines and spikelets on the edges, leaving only 13-20 spikelets in the middle, so that the fruit can grow better in the later period.

1. How to prune blooms

1. Topping: Before blooming, the newly grown branches and vines should be topping. The removed parts are generally about 10 cm long. During its growth period, the tendrils should also be cleaned up, which can save nutrient consumption and facilitate the growth of branches and later fruit grains. All side vines should also be dealt with when topping.

2. Remove the flower spikes: The nutrition of grapes themselves is It is limited. If there are too many flower spikes, they should be removed in time so that the remaining spikes can absorb enough nutrients and maintain better growth. Generally, it is enough to leave one inflorescence on each fruit-bearing branch, and the rest should be removed. 10 days before flowering, cut off the side spikes and spikelets on the sides, leaving only 13-20 spikelets in the middle. If it is not pruned, it will not be able to bear all the fruits if it grows too densely, but it will consume a lot of nutrients.

2. What happens after the results? Prune

Wait until the flowers fall before fruiting occurs, which is about a week after flowering. At this time, the grapes are about the size of mung beans. It is necessary to cut off the weak fruit kernels, the fruit kernels inside the ear, and the fruit kernels on the top of the ear. In the end, only 40-120 fruit kernels are left in each ear, so that the weight of the grape bunch after maturity can be stabilized at 300-1200. grams, which can ensure the fruit ears are even. In addition, you can cut off 1/4 of the inflorescence tips when the fruit ears grow to 15-20 cm. This can save nutrients, facilitate fruit growth, and better achieve high yields.
