Layering is a technique of plant propagation where a new plant remains at least partially attached to the mother plant while forming new roots. Layering can occur naturally through modified stem structures, but plant propagators can also assist the process by wounding the stem where the roots are to form and applying rooting compounds. Layering is a tried and true method of asexual propagation that does not require any special tools or controlled environmental conditions, like a mist bench, to facilitate rooting. The techniques required are easily mastered by the home gardener. Layering techniques allow desired shrubs, vines, and indoor plants to be propagated using less space. Hard-to-root plants propagated using layering techniques generally form roots more quickly with greater overall success than when they are propagated from cuttings. There are several methods of layering that can be used, including simple layering, tip layering, serpentine (compound) layering, mounding (stooling) layering, and French layering.
