The Art of Grapevine Grafting
Months after the harvest was completed, hundreds of thousand dormant grapevine canes begin the process of forming a perfect union between the rootstock and the graft material bud. The selection process had been predetermined with the cane material being hand selected form the cuttings form the winter pruning of the grapevines.
The union of sorts, called a scion, sounds quite simple, but in reality, the process allows a single rootstock to produce grapes from any variety of grapes. It has become the primary means for developing vines in the early stages of growth.
