Simple layering – Simple layering is done by bending a stem until the middle touches the soil. Push the center of the stem underground and hold it in place with a U-shaped pin. Roots will form along the part of the stem that’s underground.
Tip layering – Tip layering works by pushing the very tip or point of a stem underground and holding it in place with a pin.
Serpentine layering – Serpentine layering works for long, flexible branches. Push a portion of the stem underground and pin it. Weave the stem above the soil, then back down again. This method gives you two plants instead of just one.
Mound layering – Mound layering is used for heavy-stemmed shrubs and trees. Clip the main stem down to the ground and cover it. The buds at the end of the stem will form into a number of rooted branches.
Air layering – Air layering is done by peeling the bark from the middle of a branch and covering this exposed wood with moss and plastic wrap. Roots will form inside the moss, and you can cut the rooted tip from the plant.

Layering has evolved as a common means of vegetative propagation of numerous species in natural environments. Layering is also utilized by horticulturists to propagate desirable plants.
Natural layering typically occurs when a branch touches the ground, whereupon it produces adventitious roots. At a later stage the connection with the parent plant is severed and a new plant is produced as a result.
The horticultural layering process typically involves wounding the target region to expose the inner stem and optionally applying rooting compounds. In ground layering or simple layering, the stem is bent down and the target region buried in the soil. This is done in plant nurseries in imitation of natural layering by many plants such as brambles which bow over and touch the tip on the ground, at which point it grows roots and, when separated, can continue as a separate plant. In either case, the rooting process may take from several weeks to a year.
Layering is more complicated than taking cuttings, but has the advantage that the propagated portion continues to receive water and nutrients from the parent plant while it is forming roots. This is important for plants that form roots slowly, or for propagating large pieces. Layering is used quite frequently in the propagation of bonsai; it is also used as a technique for both creating new roots and improving existing roots.
A low-growing stem is bent down to touch a hole dug in the ground, then pinned in place using something shaped like a clothes hanger hook and covered over with soil. However, a few inches of leafy growth must remain above the ground for the bent stem to grow into a new plant. Removing a section of skin from the lower-facing stem part before burying may help the rooting process. If using rooting hormone, the stem should be cut just beneath a node. The resultant notch should be wedged open with a toothpick or similar piece of wood and the hormone applied before burying.
The buried stem part then grows new roots which take hold in the soil while the above parts grow as individual new plants. Once the end of the stem has grown long enough the process can be repeated, creating the appearance of a row of plants linked by humped, intermittently buried stems. Better results can be achieved when the top of the plant is closer to the vertical.
Once the process is completed, the buried section should be kept well-watered until roots begin to form. The new individual plant may require one to two years before it is strong enough to survive on its own. When it is, the original stem should be cut where it enters the ground, thereby separating the two plants.
As layering does not involve sexual reproduction, new plants are effectively clones of the original plant and will exhibit the same characteristics. This includes flower, fruit and foliage. Plant selection usually involves plants with a flexible stem.
Simple layering can be more attractive when managing a cascading or spreading plant.These plants tend to propagate in this manner anyway, and potting a new limb will give extra plants without having to sow new seed.Simple layering can also help when a plant has overgrown its pot and is drooping over the side. The long stem is layered into another pot until it roots, thus bringing it back to soil level.
