Layering
From BonsaiWIKI
See Layering soil, which is different than layering.
Layering is a method of propagation in which the actively growing cambium of branches or trunk is interupted by girdling or mechanical means ( wire tourniquet ) while the portion to be layered is left attached to the tree until roots form at the site of the layer.
REASONS FOR LAYERING
Layering is performed to propagate material, to take advantage of interesting or pleasing forms, or to improve the root system of a tree. Layering is an easy way to create "perfect rootage" on a tree with a one-sided or unattractive root system.
HISTORY OF LAYERING
Layering is a process used to induce roots to grow on a mature branch. The process of layering was probably developed in conjunction with hedging. Hedges of boxwood, privet or thorns were a convenient way to designate property boundaries, particularly in the absence of good material for fences.
