How to prune Kyoho grapes

When to prune Kyoho grapes

Kyoho grapes are pruned in winter and summer. Pruning in winter is to help it survive the winter better, while pruning in summer can help it grow better.

Cuttings: Cut off the long semi-woody branches of Kyoho grapes, leaving a green leaf on the top, and insert it into the soil. Give it appropriate sunlight and water, and it will soon take root and sprout.

Kyoho grape pruning

When pruning Kyoho grapes, focus on pruning medium and long shoots. Leave one branch every 80 cm on the main vine. Strong branches need to have 7-12 buds, medium branches need to have 4-7 buds, short shoots need to have 1-3 buds, weak branches need not have buds, and excess branches and thin branches should be thinned out before flowering.

Tips for pruning Kyoho grapes

After Kyoho grapes sprout in spring, double buds, weak buds and useless buds should be removed as soon as possible, leaving only one strong bud in each bud eye. The second bud removal should be carried out 10 days after the first bud removal and last for 2-3 weeks. The main buds should be selected and all other buds should be removed.

Moderate pinching of Kyoho grapes before flowering can control vegetative growth and increase fruit set rate. Pinching should be done when 5 to 7 leaves are left above the flower cluster, 4 to 7 leaves are left on the fruiting branches, and 15 to 20 leaves are left on the vegetative branches. All side shoots below the fruit cluster should be removed, and 1 to 2 leaves are left on the side shoots above the fruit cluster. Repeat pinching to ensure sufficient nutrients.

Results of Kyoho grape pruning

Two weeks before flowering, the inflorescences of Kyoho grapes should be thinned and pinched at the same time. One inflorescence should be left on each branch, and two inflorescences should be left on strong branches. 1/3 of the tip of the ear should be pinched off, and the diseased and weak ears that are too dense and uneven should also be thinned out.

Things to note when pruning Kyoho grapes

Kyoho grapes need to be pruned after harvesting to reduce nutrient consumption, promote branch maturation, increase the fruit set rate in the next year, and promptly remove branches that are too strong, too dense, diseased, and insect-infested to keep the plants ventilated and light-permeable.
