Detailed explanation-1: -A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil.

Detailed explanation-2: -Cutting is the method used for vegetative propagation where the vegetative part of the stem is cut and buried in the soil. The part which is used in cutting has the nodes which have axillary buds which help in propagation.

Detailed explanation-3: -Asexual or vegetative plant propagation Asexual plant propagation methods produce new plants from vegetative parts of the original plant, such as the leaves, stems and roots. These methods are generally referred to as vegetative propagation.

Detailed explanation-4: -Artificial Vegetative Propagation The most common types of artificial vegetative reproductive techniques include cutting, layering, grafting, suckering, and tissue culturing. These methods are employed by many farmers and horticulturists to produce healthier crops with more desirable qualities.

Detailed explanation-5: -Vegetative Propagation by Roots In this process, new plants grow out of the modified roots called tubers. In fact, in some plant species, roots develop adventitious buds. These buds grow and form new plants/sprouts under the right conditions. For example, Sweet potato and Dahlia.
