A layer is the rooted stem following detachment from the parent plant. Leaves are connected to the underground stem from the bulbs to store plant food. Throughout late summer, leafless, underground branches known as rhizomes enter the thick levels of soil near the base of the original plant. Mint grows by this process. The most frequent use of forest geneticists and tree breeders in vegetative propagation has been to move genes from selected trees to a convenient location, typically a gene bank, a clone bench, a cloning orchard or seed garden where genes can be recombined with pedigrees. So if you grow a daffodil bulb, a couple of years later, there are different bulbs vying for fertilizer, space and access to the light. Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or some specialised reproductive structures (vegetative propagule).

Sometimes hormones (growth promoters) are injected into the contents for nurturing and inducing quick plant development. Stem-cutting is another common asexual propagation technique, suited well to herbs and house plants. Layering exploits this property of stems. With the help of a technician, the respective parts of a plant are segregated and cultured in a clinic. The technique has been applied to a substantial number of commercial vegetatively propagated plant species. It involves development of roots on a stem while the stem is still attached to its parent plant. The development process for roots on a stem or branch is called layering, while still attached to the plant. Corms are found in these animals.
