v. induce a twig to root while still attached to the parent plant (Gardening); arrange in layers; cut in layers (as of hair)

Layering is a means of plant propagation in which a portion of an aerial stem grow roots while still attached to the parent plant and then detaches as an independent plant. Layering has evolved as a common means of vegetative propagation of numerous species in natural environments. Layering is also utilised by horticulturists to propagate desirable plants.
