Grafting with Tina
knives that is. Here is a youtube link of a professional Dutch grafter. He is grafting apples with the choice of professionals, Tina. When you do this many grafts the knife must be comfortable in your hand. It must be high quality steel so you don't have to stop and sharpen frequently.
This is whip & tongue method. Fruit trees, flowering fruit trees, amelanchier, fringe trees, lilacs and many other ornamentals are grafted like this.
I really think that the Dutch are the master grafters, notice how the knife never leaves his hand.
Having a professional on youtube like this is rare, most of the videos are of amateurs and novices. Digging rootball demonstrations are laughable.
