 The Simonit&Sirch Preparatori d’uva method, consists of a set of modular processes that, if implemented
 steadily over the years, allow for controlled plant growth by means of pruning only one or two year-old wood.


 The permanent structure of
 grapevine is comprised of the
 trunk and the root system. The
 efficiency and health of those
 organs is at the base of the
 correct physiology of the plant.

The main problem of traditionally with the “traditional” method. pruned spurred cordons is the Before the shift it is wise to assess the health In the case of spurred cordon vineyards, the first loss of vegetative points.

It there is no and beyond saving, the trunk shall have to be to restore the lost vegetative significant sign of necrosis on the head, which would redeveloped from the ground up. points (picture 35). The retrieval of the “secondary collectors” or vegetative points happens by 35 means of winter pruning that gets rid of all redundant shoots and a timely intervention to remove the buds on the trunk. The removal of redundant shoots, that is, those located outside of the arrangement of the horizontal cordon, allows for a balanced distribution of the plant’s efforts that are thus focused on the spurs left in place. It is important to remove the downward spurs. This work causes better and more uniform blossoming of the chosen vegetative points. Another important help to vegetative point consolidation is 36 provided by a timely intervention to remove the buds on the trunk, to focus the energy given 32 33 34 to the production of buds only in those spots defined during winter pruning.
