It’s time we had this conversation. Propagation is simply how plants reproduce. They are not embarrassed about it, so don’t be shy! Plant propagation can either be sexual or asexual. As with animals, sexual propagation results in offspring that is genetically different from the two parents. But unlike animals, plants can also propagate by cloning themselves, resulting in a baby plant that is exactly identical to the parent. There are a bunch of different ways plants can propagate, with and without your help. These include:
Seeds
Spores
Tip, stem, or leaf cuttings
Tubers, bulbs, or corms
Rhizomes or stolons
Air layering
Unless you are advanced in horticultural science, you will probably not be dealing with sexual propagation (seeds and spores). Asexual reproduction through cuttings or bulb division, on the other hand, is fairly simple for houseplant owners to achieve, and some plants will even replicate themselves without you having to do anything at all!
