Split the rootstock with a blade or chisel.Cut off the top of the vine about 30 minutes or so before grafting.There is a five step process for the cleft graft: It is for larger diameter vines and the scion must be dormant. The cleft graft is a simple method that requires little skill. There are several types of grafts that can be used, including: The scion is taken while dormant for most types of grafting however, actively growing tissue can be used in some cases. Scion wood collection is the same as for taking cuttings. The vines to be grafted must be healthy and vigorous, without disease or insects, and relatively young.

Already existing vines are candidates for grafting if the cultivar is not economical or not appropriate for the site. Grafting is a time-consuming process requiring patience and practice. Increased cambial contact (the more area that touches) between scion and rootstock increases the chances of success. It is subject to drying out, so take steps to prevent that situation. This area leads to the formation of the graft union of the scion and rootstock. The cambium is a single layer of cells located just below the bark. The only requirement for grafting and budding is viable cambium contact. When grafting, the scion will contain multiple buds, but budding consists of a single bud. This is the process of placing a shoot system (a scion) of one cultivar or species on the root system (a rootstock) of another. Grafting or budding is an asexual propagation technique.
