The grafting technique permits to obtain – within the same variety – homogeneous plants. For
example, if we sowed different kernels of a white paste peach-tree variety, we could obtain some
plants with good fruits and some not, or even no plants with good fruits at all. 
With the grafting instead, we can reproduce many varieties maintaining the plant and fruit
characteristics. Another advantage is given by the opportunity to choose the most suitable rootstock
for the variety that we want to graft. There are various types of grafting that can be practised
depending on the different seasons of the year.
Winter grafting, to be done in February: the cleft grafting, the English double cleft, the crown
and the triangle one, etc.
Summer grafting, to be done in August: the resting bud, the approach, the flageolet grafting, etc.
Once the grafting has been carried out, it is important to remove the wild suckers in order to obtain
a nice plant.
“Table” grafts carried out on the vine. This type of grafting is called this way as it is not carried out
on the plants in the field, but on a table in a warehouse, manually, with appropriate devices that
create a groove-and-tongue joint called omega.
After the grafting, one must proceed with the immersion in paraffin at a low fusion gradation, being
careful enough to cover the grafting point. Then, it is necessary to stratify the rooted cuttings in
cases with fir sawdust or peat. After this step, one must proceed with the vertical planting of the
cutting grafts, to promote the growth of the grafted rooted cutting. 
In addition, we should not forget the regraft of adult trees.
It is a grafting that is practised on plants in production and on adult trees, to change the variety or
solve various problems, like those related to pollination.
