What is one reason for summer pruning grapes?

One important reason for summer pruning grapes is to alleviate wind damage and increase shade. During the growing season, grapevines can become quite dense, which may lead to increased wind resistance and potential breakage. By pruning in the summer, growers can manage the canopy more effectively, allowing for better air circulation throughout the vine. This not only helps to reduce the risk of wind damage but also creates a more balanced microclimate under the vine, providing shade that protects the developing grapes from excessive sun exposure and potential sunburn. This practice ultimately supports healthier vine growth and can lead to improved fruit quality.
