Grafting through is a horticultural technique where a part of one plant, called the scion, is joined to another plant, known as the rootstock. This method allows the scion to benefit from the rootstock's established root system, improving growth and fruit production. It is commonly used in the cultivation of fruit trees and ornamental plants. This technique can enhance disease resistance and adaptability to different soil conditions. Grafting through is often employed with species like apple trees and roses, allowing gardeners to combine desirable traits from both plants for better overall performance.
