Layering  Horticulture  ]

Dictionary of botanic terminology - index of names

  A common method of propagation, by which a a shoot of a plant is rooted while still attached to the parent plant laying on or partially buried in the soil by securing it to the soil with a piece of wire.  
Layering is a method of propagating a plant where the stem is pegged down to the soil, still attached to the mother plant, to make it form adventitious roots and create a new plant which is capable of independent growth after separation from parent plant.
This is the simplest method of propagation, although the least efficient in terms of time and number of regenerants per plant. Many woody herbs propagate by layering naturally when trailing branches grow close to the soil surface and send down roots.

There are two primary methods of layering.
  • In ground layering: A proces of producing roots in which a low-growing branch is bent to the ground and covered with soil.
  • In air layering: A process of producing roots on old aboveground branches by stripping bark from an area and wrapping in moist rooting medium (e.g. sphagnam moss), or by wrapping moist rooting medium around a node on an stem.
