What is the method of tree propagation that involves rooting a branch called?

The method of tree propagation that involves rooting a branch is known as layering. This technique allows a branch to establish roots while still attached to the parent tree, which provides it with the necessary nutrients and water during the rooting process. There are several types of layering, such as air layering and mound layering, each of which can be effectively used for different species of plants.

In contrast, grafting involves joining two different plants together so they can grow as one, which is distinct from rooting a branch. Cutting refers to the process where a segment of a plant, usually a stem or leaf, is cut and placed in a medium to develop roots on its own, but it does not involve the branch remaining attached to the parent plant during rooting. Seedling refers specifically to a young plant that has grown from a seed, which is a different method of propagation altogether. Understanding these distinctions helps clarify why layering is the correct method for rooting a branch.
