Grafting is a gardening technique where a part of one plant, called the scion, is attached to another plant, known as the rootstock. This method allows the two plants to grow together as one, combining their strengths. For example, a gardener might graft a fruit tree variety that produces delicious apples onto a sturdy rootstock that is resistant to diseases. This process is beneficial because it can enhance the growth and fruit quality of the new plant. Grafting is commonly used in the cultivation of roses and grapevines, allowing gardeners to create unique varieties and improve yields while maintaining desirable traits.
