Where should the cuts at the end of a spur and canes in grape pruning be made?

Making cuts about 1/2 inch above the last bud is essential in grapevine pruning. This practice is beneficial for several reasons. First, cutting above the bud allows for a small amount of wood to remain, which helps protect the bud from potential damage or desiccation. If cuts are made too close to the bud (such as directly at the bud), there is an increased risk that the bud may dry out or be compromised, thereby reducing the chances of successful growth in the spring.

Moreover, leaving a little extra wood promotes the healing process after pruning. The resulting callus tissue formed will provide a protective barrier as the vine recovers from the pruning process. This practice also encourages new growth to emerge effectively, as the bud has better access to nutrients and resources, leading to a healthier and more productive vine in the following season.

Understanding the proper placement of cuts is vital to achieve optimal vine health and ensure a good yield during the growing season, making this technique crucial for any successful grapevine pruning strategy.
