Air layering is a simple form of vegetative propagation where new plant is produced on the stem. This new plant is later separated and planted. In air layering a ring of bark of 4-8 cm length is removed from the stem. This part is covered with the moist soil or moist coconut fibres and it is wrapped in a polythene sheet. The moist condition is maintained inside the polythene sheet by spraying water. The injured region of the stem begins to produce roots. So that the branch is cut and planted this produces a new plant.
