Alright, lets get into the required steps. Firstly it is required that you have a sharp knife that can easily cut through your branch, after you have your knife carefully cut the scion and the rootstock and make sure they match. Carefully crate the graft, slowly adding the scion to the rootstock. Finally seal it up with buddy tap making sure the tape is tight.
once you've made and sealed your graft you need to look after the graft to keep it healthy. You need to maintain a good seal on the graft keeping it tight so the graft is held together. When growing your graft try keep it in a humid space but not in a wet space. its important to suppress the growth of the rootstock because rootstock can sucker and send out shoots that revert the way the graft is growing. It is important to remove any new sucker growth that appears above the line between the cut.
It important to know that when doing a whip and tongue graft it best works with plant material between 1/4 of a inch to a half of a inch in diameter. And that's all! Have fun grafting.
