the spreading of something (a belief or practice) into new regions.

Plants can be propagated sexually (via seed) or asexually (through cuttings, layering, grafts, or root/bulb division). Propagation should always be performed with clean, sterilized tools to prevent the spread of disease. Plants undergoing asexual propagation undergo stress and special consideration should go toward providing it nutrients that can be easily absorbed (see liquid fertilizers). In the case of cuttings, root hormones or willow water should be considered.
