Grafting or graftage is a technique used in horticulture that consists of taking tissues from one plant and putting them onto another plant. The two plants will then grow together. The technique is a type of vegetative reproduction. Grafting is commonly used with roses, and fruit trees. It only works with dicots and gymnosperms, and not with monocots. Monocots do not have a vascular cambium, which is needed for the process to work. There are several different methods of grafting; each method has its advantages and drawbacks.
