Whip-and-tongue graft is a type of grafting technique used to join a scion and rootstock. In this method, both the scion and rootstock are cut at an angle and fitted together with matching "tongue" cuts, which interlock to provide a strong, stable connection. The whip-and-tongue graft allows for better contact between the vascular tissues, improving the chances of a successful graft union. This technique is often used in fruit tree propagation.
