What is a common way to propagate house plants?

Propagating house plants can occur through various methods, each suitable for different species and circumstances. The option regarding propagation from seeds is a common method because many house plants can be grown from seeds, allowing for a wider variety of plants to be cultivated. Germination from seeds generally requires proper moisture, light, and temperature, but once established, seedlings can be transferred to larger containers and cared for as they grow.

While grafting, cuttings, and division are all valid propagation techniques, they each have specific applications and limitations. Grafting is primarily used for certain woody plants and may not be effective for many typical house plants. Propagation from cuttings is also common and can be very successful for many house varieties, but it is not the only method. Division tends to apply mostly to certain herbaceous perennials rather than house plants specifically. Thus, while the answer concerning seeds is correct and encompasses a broad range of possibilities, the other options, while valid in other contexts, do not represent the most common method for house plant propagation as a whole.
