Grafting

Definition

Grafting is a horticultural technique where tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together. This method is used to propagate desirable traits in plants, such as improved fruit quality or disease resistance.

3. The process often takes place during specific seasons when plants are actively growing, typically in spring or fall.
4. Grafting can help combine desirable traits from two different plants, such as drought resistance and high yield.
