Answer:
Propagation by cuttings.
Step-by-step explanation:
Propagation is the process of growing new plants from existing ones. There are various methods of plant propagation, including seeds, division, and cuttings.
A gardener cut a branch from a shrub and planted it in a small pot where it grew into a new shrub. This method of growing a new shrub is known as propagation by cuttings. In this method, a cutting is taken from an existing plant, and the cutting is rooted in soil or water to form a new plant. The new plant will have the same characteristics as the parent plant.
Propagation by cuttings is a popular method for shrubs and other woody plants as it allows for the easy and efficient production of new plants from existing ones.
