Layering is one of the oldest techniques to propagate woody plants. Unlike in stem cuttings, in layering, a stem is induced to root when it is still attached to and sustained by the' parent plant so that the parent plant supplies the new individual with water and food particularly carbohydrates, proteins and with hormones until it makes its own food and hormones. Layering does not require close attention regarding the control of watering, humidity, and temperature of propagating frames that the cuttings often require. When the root formation is complete, the layers are severed from the parent and are treated essentially in the same way as the root cuttings.
