What is crown suckering in grapevines?

Crown suckering in grapevines refers specifically to the process of managing unwanted growth that emerges from the base of the vine, often termed the crown. This growth can interfere with the health and productivity of the grapevine by diverting energy from the main productive shoots. By removing these suckers, growers can ensure that the nutrients and resources are concentrated on the main vine structure and fruit production, which ultimately leads to better grape quality and yield.

This practice also maintains the overall structure of the vineyard, preventing overcrowding and improving airflow, which can reduce the risk of diseases. Thus, removing unwanted growth in the crown directly supports the vitality and productivity of the grapevine, making it a key practice in viticulture management.
