(ˈleɪərɪŋ) n1. (Horticulture) horticulture a method of propagation that induces a shoot or branch to take root while it is still attached to the parent plant2.

lay•er•ing

(ˈleɪ ər ɪŋ)

n. 1. the wearing of lightweight or unconstructed garments one upon the other, as for style or warmth. 2. a method of propagating plants by causing their shoots to take root while still attached to the parent plant. [1920–25]

layering

A method of propagation where a wounded stem is encouraged to root in soil or compost while still attached to the parent plant.

layering

layering,

horticultural practice of propagating a plant by rooting a branch before severing it from the mother plant. Typically the branch is bent and a section that has been slit or broken on the underside is covered with soil and held in place by means of stakes or pins. Trench layering induces new shoots from a length of buried branch. In mound, or stool, layering, the many shoots of a closely cropped young plant are heaped with soil. Air (or pot, or Chinese) layering is used when the branch cannot be bent to the ground; peat moss or some other suitable rooting medium is attached to a cut place on the branch. Layering is used mostly for multiplying plants not easily propagated from cuttings. Some plants propagate naturally by layering, e.g., raspberries, strawberries, and chrysanthemums.
