The pruning of the vine is one of the most important practices in the vineyard because it has a direct impact on the growth of the vine and the grape harvest. But pruning of the Old Vine is also a significant ceremonial event; on this occasion, the city of Maribor donates the scions of the Old Vine to its partner cities, communities and countries all over the world.

The pruning and ceremonial donation of scions are accompanied by a cultural-ethnographic programme.
