In floriculture, what is layering propagation?

Layering, also called mound layering, is the practice of burying a branch of a flowering plant in moist soil, or wrapping the branch with other moisture-retaining material (such as moss), creating dark and moist conditions for rooting; once roots have formed, the branch is cut away from the mother plant to become a new plant. Like cuttings propagation, it uses the regenerative capacity of plant organs to propagate, and it is mostly used for flowering plants that are difficult to root from cuttings, or for woody flowering plants with many roots and leaves. Its fundamental characteristic is that the vegetative organ separated from the mother body has the capacity to regenerate, and can grow adventitious roots and adventitious buds on the detached part, thereby developing into an independently living plant. Its fundamental characteristics are: it can maintain the excellent traits of certain cultivated plants, and the propagation speed is relatively fast.
