Layering Method of Plant Propagation
Layering is a method of plant propagation by which a part of the plant is bent down and covered with soil, so that it may emit roots before being separated from the parent plant. in some instances, it is sufficient to remove all buds from the shoot, with the exception of a few near its extremity, and to bend it and peg it down so that a part of its proximal end is buried beneath the soil. In others it is necessary partly to cut through the stem at the point where it is to be covered with soil.
