Abstract
Layering is a method of propagation that encourages adventitious roots to form on stems while they remain attached to the parent or “stock” plant. This ancient propagation method takes advantage of the natural propensity of plant stems to initiate roots when they are broken or bend and touch the ground, as is often observed with rhododendron stems and blackberry canes. Layering can range from simple layering, in which a stem is bent over and partially buried in the ground, to air layering, in which the stem is wounded and wrapped with a moist medium for rooting. By whatever method, plant propagation by layering is a relatively slow process, requiring 1 to 18 months, and does not often come to the mind of the plant propagator as a commercially viable technique. However, for difficult-to-root plants, technologically simple propagation operations, or when only a small number of quality plants are needed, layering can offer a high rate of success. Familiarity with the propagation technique of layering is a valuable horticultural skill.
