Propagation is the process of creating new plants from existing ones. This can happen in several ways, such as through seeds, cuttings, or layering. For example, when you plant a seed from a flower, it grows into a new plant. Similarly, if you take a cutting from a houseplant and place it in water, it can develop roots and become a new plant. In addition to plants, propagation can also refer to spreading ideas or information. For instance, when a new technology, like social media, becomes popular, it propagates quickly as more people share it with others. This helps ideas grow and reach a wider audience.
