The whip and tongue graft is best suited when the scion and root stock have similar diameters. I have a scion wood with about half of the diameter of the root stock. To use the whip and tongue with different diameter, I have two choices: align the scion on one size or make off the center cut. I decided to use the later method since the diameters of the root stock is much bigger than the scion wood.
