Vine pruning, in terms of period and intervention techniques, depends on several factors and has both productive and vegetative goals.
Pruning is mostly done in winter (winter or dry pruning), a time when the plant completely loses its leaves.
Interventions allow the plant to be "lightened" so it can better withstand the cold and ensure a bud load in line with future production.
A distinction should be made in this regard according to the age of the vines.
For older ones, the ideal time for winter pruning resides in January/February, while for younger ones -we are talking about those that are less than three years old-the most suitable time is in March, when the winter season is over, so that the parts most damaged by the weather of the cold months can be removed.
In addition to winter pruning, there is also summer or green pruning, which is also aimed at removing excess material, in this case green material, from the plants that does not contribute in any way to improving production.
Different types of farming also affect the period and pruning techniques.
Among the most common training and cutting methods in Italy are: the Guyot, the Spurred Cordon method and the Sapling.
According to the Guyot method, about midwinter, all vegetation is removed except for a shoot (fruiting head) and a small spur bearing two or three buds.
With the Spurred Cordon, on the other hand, a few months after the onset of winter rest, pruning is carried out, leaving one or two branches that will remain on the vine for at least four to five years and on which four spurs will be left equidistant from each other, which will be renewed from year to year with subsequent pruning.
In contrast, the Sapling method allows small vegetation to be maintained (from about 20 cm to 1 m), which allows it to develop in poor soils or at low temperatures.
It is between January and February that we do the winter pruning of our vines, which draw the hills of the Trebbia Valley finding new vigor and energy to guarantee the quality that our wines have expressed for more than 75 years.
