The best time for pruning vine begins to when it has lost all its leaves and lasts for the entire winter season.
As regards the colder locations it is recommended to postpone as much as possible pruning to avoid as soon as possible frost damages.
The pruning is aimed primarily at the selection of gems and will then be completed by the so-called green pruning during the summer, when the plant will have regained vigor and will need to thin out the leaves and branches depending on the exposure of the grapes.
Pruning can be different depending on the chosen method of training, the most popular being the cordon and the Guyot, but there are many, such as: double Guyot, tendone, pergola, and tree pruning.
