Grafting Techniques and Practices

The video tutorial discusses grafting, a method of vegetative propagation where stems of two different plants are joined to grow a single plant with characteristics of both. It covers three types of grafting: whip, tongue, and cleft. Whip grafting involves joining equally thick stock and scion with a slanted cut, tongue grafting uses interlocking cuts, and cleft grafting involves inserting a scion into a larger rootstock split. Each method is explained with steps and diagrams, emphasizing the importance of airtight sealing for successful grafting.
