Crown division is the easiest propagation method that amateur gardeners can utilise to show off their skills. It is a form of plant propagation in which new plants are not grown from seeds or bulbs but are rather separated from the parent plant. The crown of a plant is where its stem meets the roots. The idea is to divide the plant at its crown so that each separated plant has its own shoot and root system, and is capable of producing new plant. This propagation technique has long been used to propagate bulbs such as garlic and saffron. Flowering plants like Orchids, Carnations, Rose plant, Daylilies and Dahlias are also commonly propagated by this method.
Stems that are attached to their parent plant are capable of forming roots on coming in contact with a rooting medium. Layering exploits this property of stems. It involves development of roots on a stem while the stem is still attached to its parent plant. A layer is the rooted stem following detachment from the parent plant.
