Final answer:
Plant layering is a method of plant propagation where a stem is buried to generate new plants, as used with jasmine and bougainvillea.
Step-by-step explanation:
Plant layering is a propagation technique where a stem is bent and buried in the soil to form a new plant. An example found on Lincoln Smith's Forested involves jasmine or bougainvillea, which can be propagated by layering, producing new plants while still attached to the parent. Air layering is also practiced where the stem's covering is removed and wrapped with moss to encourage root growth before transplanting.
