Graft off is a term related to horticulture, which refers to grafting a smaller branch onto a larger one of a different species or variety. The process involves cutting a small branch, referred to as a scion, from one plant and attaching it to a related plant, known as the rootstock. This allows the scion to grow on a larger and more vigorous root system. Synonyms to the term graft off include grafting on, grafting up, and budding. These synonyms are often used interchangeably, and the process of grafting is practiced in agriculture laboratories, fruit orchards, and scientific research centers.
