Detailed explanation-1: -A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems.

Detailed explanation-2: -Most frequently, however, either a stem or leaf is used. A stem cutting includes a piece of stem plus any attached leaves or buds. Thus, the stem cutting only needs to form new roots to be a complete, independent plant.

Detailed explanation-3: -Known as “propagation, ” starting plants from cuttings is one of the easiest and least expensive ways to expand your garden, but there are other benefits, too. When plants are started from seeds, each new seedling varies-like siblings in a human family. But with stem cuttings, each new plant duplicates its parent.

Detailed explanation-4: -Asexual propagation, sometimes referred to as vegetative propagation, involves taking vegetative parts of a plant (stems, roots, and/or leaves) and causing them to regenerate into a new plant or, in some cases, several plants.
