Whip-and-tongue grafting with a flat blade
The whip-and-tongue graft joins a scion and a rootstock of the same thickness, usually in late winter or early spring. A flat, straight edge like this 7.5 cm spatula-tip blade suits it, because it cuts the long faces truly flat.
- Make one long slanting cut across the top of the rootstock, roughly three times as long as the stem is thick, in a single draw of the grafting knife.
- Make an identical cut at the base of the scion.
- On each face, cut a short tongue: a slit starting about a third of the way down from the tip, running roughly with the grain.
- Slide the two pieces together so the tongues interlock and the bark lines up on at least one side.
- Bind firmly with grafting tape and seal the tip of the scion.
