The main summer pruning practices for grapes are as follows for reference:
① Bud removal. In early summer, promptly remove all secondary buds and latent buds sprouting beside the main buds of the grape.
② Shoot thinning. After new shoots emerge, according to the vigor of growth and the quality of the flower clusters, promptly remove fruitless shoots, latent-bud shoots, and overly dense tender shoots.
③ Removing secondary shoots. Except for leaving one secondary shoot at the top and 1 to 2 tender leaves, remove all the rest.
④ Pinching. 5 to 6 days before the grape blooms, pinch the fruiting shoot by leaving 6 to 8 leaves above the flower cluster.
⑤ Fruit thinning and removing the tips of flower clusters. For fruiting shoots over 10 cm, leave 2 flower clusters per shoot; generally, leaving 1 flower cluster is sufficient.
⑥ Tying new shoots. When new shoots grow to 30 cm to 40 cm, tie them to the trellis, and take care to arrange them evenly to prevent them from being broken by wind. As the new shoots continue to grow, tying needs to be done 3 to 4 times.
⑦ Removing tendrils. Grape tendrils consume a great deal of nutrients, so throughout the entire growing season of the grape, tendrils should be promptly removed to reduce nutrient consumption.
