Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure. Plant Propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual.

Natural layering typically occurs when a branch touches the ground, whereupon it produces adventitious roots. At a later stage the connection with the parent plant is severed and a new plant is produced as a result. ... In ground layering or simple layering, the stem is bent down and the target region buried in the soil.
