What is the purpose of removing water sprouts during crown suckering?

Removing water sprouts during crown suckering primarily serves to enhance sunlight penetration. Water sprouts, which are vigorous, upright shoots that often emerge from the crown or trunk of the vine, can create dense foliage that limits light exposure to the inner parts of the vine and surrounding areas. By eliminating these shoots, sunlight can reach more of the leaf surface, which is crucial for photosynthesis and overall vine health.

Improved sunlight penetration can lead to better fruit quality and increases the overall ripening of the grapes. This practice also encourages air circulation, reducing the likelihood of disease and promoting better fruit set and yield. Therefore, focusing on enhancing sunlight penetration through the removal of water sprouts aligns with the goals of maintaining a productive and healthy grapevine.
