Cuttings are parts of plants that are cut and separated from the mother tree and brought to form roots and/or shoots and eventually develop into entire plants. Cuttings can be formed from roots, leaves or stems. Propagation from stem cuttings is the most important method in forestry. The age of the tree and branch from where cuttings are collected has a very strong effect on rooting. Cuttings taken from young trees usually have a much better rooting than cuttings from older material.
