Layering is a technique for Plant Propagation in which a portion of an aerial Stem is encouraged to grow Root s while still attached to the parent plant, and then removed and planted as a new plant. The process typically involves wounding the target region and optionally applying Rooting Compound s. In ground layering, the stem is bent down and the target region buried in the soil. This is done in Plant Nurseries in imitation of natural layering by many plants such as Bramble s which bow over and touch the tip on the ground, at which point it grows roots and, if separated, can continue as a separate plant. Ground layering is the typical propagation technique for the popular Malling-Merton series of Clonal Apple rootstocks, where the original plants are set in the ground with the stem nearly horizontal, which forces side buds to grow upward. After these are started the original stem is buried up to the tip. At the end of the growing season, the side branches will have rooted, and can be separated while the plant is dormant. Some of these will be used for Grafting rootstocks, and some can be reused in the nursery for the next growing season's crop. In air layering, the target region is surrounded in a moisture-retaining wrapper such as Sphagnum Moss , which is further surrounded in a moisture barrier such as Polyethylene film. In either case, the rooting process may take from several weeks to a year. Layering is more complicated than taking Cuttings , but has the advantage that the propagated portion can continue to receive Water and Nutrient s from the parent plant while it is forming roots. This is important for plants that form roots slowly, or for propagating large pieces. EXTERNAL LINKS ` |
