Marcotting propagation, or air layering, is a vegetative method of propagation that involves rooting aerial stems that are attached to the parent plant. There are a number of advantages of marcotting propagation that make it favoured over other vegetative methods. These advantages include:
- Larger plants, particularly those that are readily mature, can be produced in a much quicker time.
- The process of marcotting is one that is reasonably easy to carry out. If the method is being used for a small number of plants, it can produce more layers without much effort, equipment or skill.
- Air layering plants ensures a much higher rate of rooting success. This is particularly useful when there are clones involved as these typically do not root easily.
- Only a small number of the layers can actually be produced from a parent plant.
- In order to produce a vast amount of layers, a wide area is required to first produce the stock plants.
- The bigger layers involved in air layering require some special care to ensure that they can be established independently.
