Air layering is a method of propagating new trees and shrubs from stems still attached to the parent plant. The stem is wrapped with damp moss to encourage roots to form.Because it is an asexual process, the genetic material is directly transferred to the newly rooted stem, which may be cut away from the parent to start a new plant. To learn how to air layer, you need to consider how to get the plant material to root. Each plant is different and responds differently to the methods.


1. explain in detail what air layering is and how it works

2. list the advantages of air layering

3. air layer a plant stem correctly

4. successfully produce a new plant using the air layering technique


  • 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


1. This technique results in a good-sized plant in a matter of weeks instead of months or years

2. There is a minimum of disturbance and no adverse effect to the mother plant

3. During propagation, both the mother plant and the new plant continue to develop

4. The new plant will have characteristics identical to the mother plant

5. The success rate is high when using good-sized plants

6. You can shorten the juvenile period of a plant (i.e., the time required for the plant to attain it's fruit bearing stage). Additionally, the new plant tends to be stronger and more mature than those propagated by any other technique

7. More rapid and stronger root growth reducing the period of propagation.


This technique is initially labor intensive and time consuming.
