When to thin grape clusters
For many girls, the related content of growing grapes at home, such as when to thin grape clusters, please see the detailed introduction below.
Grape thinning should be done as early as possible, preferably when the fruits are the size of mung beans, at which time it can also be called secondary shaping. Mainly, overgrown and dense branches are trimmed or removed, leaving single-layered fruit grains. Twisted spikes or irregularly sized grains are trimmed with a thinning剪 to make the fruit clusters cylindrical.
Afterward, when the fruit grains are about the size of soybeans, a comprehensive thinning is carried out. Remove the grapes that are obviously smaller, 1 or 2 rounds. After trimming, the fruit clusters become sparse, but it's fine, they will become full again after a while. Then, you will need to thin again, removing the obviously small grains. Thinning should be done in multiple rounds, especially for small-grained varieties like rose-scented grapes. If not thinned, they will all become misshapen due to compression. For most varieties, the earlier thinning is done after the fruits have set, the better. Not only does it save effort, but it also allows the fruit grains to increase in size sufficiently.
Precautions for grape thinning
1. Do not thin when there is dew to prevent sunburn.
2. Try to minimize hand contact with the fruit surface during thinning, as excessive body temperature can easily damage the fruit grains.
3. Do not rotate the fruit clusters back and forth during thinning to prevent twisting the fruit stems.
