Layering

Definition

Layering is a method of asexual plant reproduction in which a stem grows roots while still attached to the parent plant. Once the new roots are established, the stem can be cut from the parent and grown independently.

1. Layering allows for the production of genetically identical offspring.
2. There are different types of layering, including simple layering, tip layering, and air layering.
3. Simple layering involves bending a low-growing stem to the ground and covering part of it with soil.
4. Air layering requires wounding a stem and wrapping it with moist sphagnum moss and plastic to encourage root growth.
5. Layering is commonly used for plants that are difficult to propagate by seeds or cuttings.
