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.ayering is a means of plant propagation in which a portion of an aerial stem grows roots while still attached to the parent plant and then detaches as an independent plant. Layering has evolved as a common means of vegetative propagation of numerous species in natural environments.
This type of propagation has a higher success rate than cuttings because it allows the new plant to grow roots while still attached to the parent plant. Like propagation by cuttings, air-layers are genetically identical to the parent plant. The best time of year to do air-layers is May through September.
