What is the term for the spur left after cane pruning?

The term for the spur left after cane pruning is renewal spur. This refers specifically to the short piece of vine left after pruning, which is intended to produce new growth and fruit in the coming season. By leaving this spur, growers ensure that they have a source of new, healthy shoots that can bear fruit, while also maintaining the overall health and structure of the vine.

The renewal spur is crucial in the management of the grapevine’s production cycle, providing a way to rejuvenate the vine and promote fruiting in subsequent years. This practice is fundamental to achieving the balance between growth and fruit production that is necessary for successful grape cultivation.
