Propagation is the process of creating new plants from a variety of sources, including seeds, cuttings, or other parts of the parent plant. Propagation can be done sexually (through seeds) or asexually (through methods like cuttings, grafting, or layering). It is a fundamental horticultural technique used to increase plant stock, preserve plant varieties, and reproduce desirable traits. Different propagation methods are used depending on the plant species and the desired outcome.
