What is the result of leaving too many spurs after pruning?

Leaving too many spurs after pruning leads to decreased fruit quality due to competition for resources. When a vine has too many spurs, each spur competes for essential resources such as nutrients, water, and sunlight. This competition can hinder the development of the fruits, resulting in smaller, less flavorful grapes. Additionally, excess spurs can lead to overcrowding on the vine, which ultimately affects the production and overall health of the vine. Therefore, proper pruning practices aim to balance the number of spurs to enhance grape quality and vine vitality. In contrast, the other outcomes listed do not accurately reflect the consequences of maintaining an excessive number of spurs.
