What is the method for grapevine shoot removal?

During the flowering period (early May), leave 5-7 leaves above the grape cluster with fruit and remove the shoot (pinch off the tender tip), and for those without fruit, leave 10 leaves to remove the shoot, controlling its vegetative growth, which can significantly improve the fruit-setting rate. After half a month of shoot removal, the top bud will continue to sprout and grow secondary branches, so there's no need to worry about the branches not growing anymore.

The correct method for grapevine shoot removal

We need to determine the shoot removal based on the tree's vitality. For example, if red grapes grow excessively and the shoot is not removed before flowering, the panicle will be poor the following year. We can remove the shoot 15 days before flowering, leaving 7 or 8 leaves. By the end of the physiological fruit drop after flowering, remove the shoot once more. For varieties like巨峰 (Jufeng), there is no need to remove the shoot before flowering; an inhibitor can be used instead. After flowering, also remove the shoot when the physiological fruit drop period is almost over, which will result in almost no large or small seeds, making the tree gentler and fruit-setting not an issue.

The timing of grapevine shoot removal

For grapes, the new shoot is usually pinched 2-3 days before the fruit tree flowers, removing the terminal growing point; when removing the cluster, the tip (about 1/3 of the total cluster length) should be cut off. Fruit removal can be done 30-40 days before pulling out the seedlings, but leaves should be left in front of the flower cluster to create nutrients for the flower cluster development and block strong light.
