What winter preparation does the renewal spur assist with?

The renewal spur plays a significant role in preparing the grapevine for the upcoming growing season, particularly relating to pruning practices. By promoting new growth and ensuring robust canes, the renewal spur sets the foundation for next winter's pruning. This practice involves leaving a portion of the old wood that can be cut back to improve the overall health and productivity of the vine.

When this spur is strategically placed, it allows for better bud development in the spring, ultimately leading to improved flowering and fruit production. Thus, by preparing the vine now for future pruning, you are essentially ensuring that the plant has the best chance to thrive in the following seasons. This proactive approach is crucial for vineyard management and optimization, making the renewal spur a key element in winter preparation for grapevines.
