• In this technique a vegetative branch is made to root while it is still attached to the mother plant.
  
  
• The rooted branch will be later excised and planted as a new seedling.
  
  
• Different layering techniques such as air layering techniques such as air layering, mound layering and serpentine layering are commonly practiced
  

• Pencil size shoot of the current years growth is to be selected
  
  
• On the selected shoot, preferably on the basal portion, a ring of bark is removed and the exposed wood is scraped.
  
  
• The exposed portion is further wrapped with moist inert rooting medium like Sphagnum moss, moist coir etc.
  
  
• And covered with a polythene sheet making it air tight
  
  
• This branch is left undisturbed on the mother plant for about 2-8 weeks depending on the species
  

During the course several adventitious roots emerge from the base of the exposed bark, which is covered

• The rooted branch will be later cut below the covered portion and planted as a separate seedling

Rooting in Air Layer	Air Layer Ready for Planting

• A long and supple branch is selected
  
  
• Ring of bark is removed at the base and buried in the soil
  
  
• In the due course, roots emerge from the buried portion
  
  
• After sufficient emergence of the roots the branch will be separated from the mother plant and planted as an independent plant

Trenching Layering	Multiplication of Rootstock through Mound Layering

• A series of such layering done on a single long branch that is buried and exposed alternately makes serpentine layers
  
  
• Serpentine layering can be tried for species, which have drooping long and supple branches.
  
  
• In the case of medicinal plants, serpentine layering is seen in very few species such as Tinospora cordifolia (Jivantika, Tippatiga), Celastrus paniculatus (Gundameda, Pallerutiva)
