What is the primary goal of spur pruning in Tokay grapevines?

The primary goal of spur pruning in Tokay grapevines is to ensure healthy cane growth. Spur pruning involves cutting back the vines to short stubs or spurs that contain one or two buds. This method encourages robust growth of new canes in the following season, which are essential for fruitful vineyard production.

By focusing on healthy cane growth, spur pruning helps to optimize the balance between vegetative growth and fruit production. When the canes grow well, they are better able to support clusters of grapes, resulting in a higher yield and potentially better fruit quality. This practice also ensures that sunlight and air circulation reach the interior parts of the vine, contributing to overall vine health and reducing the risk of diseases. Therefore, the emphasis on promoting new growth through this pruning technique directly ties into the long-term effectiveness of grapevine management.
