What is the full process Jasvir follows for the pruning of mature vines?
Before our vines can be pruned, Jasvir must determine how many of the buds on the existing vines have died over the course of the winter. Depending on the number of bud fatalities, Jasvir will either increase or decrease the number of buds he retains.
The next step in the process is to remove any suckers that are growing at the base of the vines. In some cases, he will also remove any canes arising off the trunk below the trellis wires and he will also look for and remove any canes that have died or are damaged.
The third step is to separate out and remove any canes that have already born crop from the previous year. The appearance of the old canes is readily discernable from the newer canes in terms of surface bark which changes in colour and texture over time.
Just like you see in the video, Jasvir then chooses the healthiest canes, one on each side of the trunk, where fruiting is desired. Each cane is tied to the trellis wire for cropping later in the growing season. Below these canes, two more canes are selected and tied to each side of the trellis wire as renewal spurs. These produce shoots which then become candidates for cane where fruiting will be desired the following year.
Lastly, all other remaining canes are removed from the vine.
