Varttaminen
Varttaminen is a Finnish term referring to the practice of taking cuttings from a plant and grafting them onto the rootstock of another plant. This horticultural technique is primarily used to propagate desirable plant varieties, especially those that are difficult to grow from seed or that have specific root system requirements. The scion, which is the cutting from the desired plant, is attached to the rootstock, which provides the root system. Successful varttaminen requires careful preparation of both the scion and rootstock, precise cutting techniques, and secure binding to ensure the vascular tissues can fuse. This fusion allows for the flow of water and nutrients, enabling the scion to grow and develop. The practice is common in fruit tree cultivation, as well as for ornamental shrubs and certain vegetable varieties. It allows for the combination of desirable fruit quality or flower characteristics with the disease resistance, vigor, or soil adaptability of the rootstock. Different grafting methods exist, each suited for specific plant types and conditions. The timing of varttaminen is also crucial, often performed when both the scion and rootstock are in a dormant state or during active growth periods, depending on the technique.
