Layering is the method of artificial vegetative propagation. Stems that are attached to their parent plant may form roots where thy come in contact with a rooting medium. The development of roots on a stem while the stem is still attached to the parent plant is called layering. A layer is the rooted stem following detachment from the parent plant. In this method, a branch of plant is covered with some material and supplied with water to produce roots.
