Reasonable pruning: Queen Nina grapes need to be pruned in time in the process of cultivation and management to make the internal ventilation and light transmission better and promote flowering and fruiting. If its branches and leaves are too dense, it will affect the light receiving area. Cut off the thick branches in time and trim the long branches. Once pests and diseases are found, cut branches and burn them in time to avoid leaving germs.
