Marcotting is defined by The Free Dictionary as a method for propagation of a tree.
Marcotting, an asexual or vegetative method of plant propagation, can be done with less skill.Air layers are slightly different from other layers such as compound or tip layers.The process of root development is done by wounding a part of the plant.
In this method, roots are formed on the part of the plant that is aboveground.In other methods, the plant part is bent down on the ground.
A shoot with lots of leaves is chosen.The stem is usually about the size of a pencil, but this isn't important.The thickness and length of the stem can be different depending on the plant part, intended size, and plant species.
The stems used in marcotting are thinner in roses.The stems of plants like aglaonema and dieffenbachia are thick.
This is not the norm in marcotting.In bamboo and herbaceous plants, this procedure is not done.To root trees, shrubs and semi-woody plants, a strip of bark is first removed from around the stem.This involves pressing a knife against the bark and moving the knife in a circular motion around the stem.A similar cut is usually 2 cm to 5 cm below the first cut, but it can be wider with larger stems.The bark is pried loose and removed after the two cuts are connected by a straight cut.
The phloem and cambium are removed from the debarked portion of the stem to prevent the wound from healing and the upper and lower barks from connecting.
In some plants, an inward cut is made from below.The cut has to cross the horizontal line that marks the point at which the stem is half its thickness and end above the same point.This slanting cut must be able to severely affect the horizontal connection.
In order to serve as a wedge, coir dust, sphagnum moss or a piece of wood should be inserted into the wound.The purpose of this wedge is to keep the upper and lower cut surfaces apart.
sphagnum moss or coconut coir dust is placed around the debarked stem and wrapped with a piece of plastic sheet.If roots have developed, a transparent plastic sheet is preferred.The stems can be marcoted even with pure soil in many plant species.
Depending on earliness, the rooting medium can be as thick as 1 inch from side to side or as large as 2.5 cm.The larger the stem, the thicker the rooting medium.
There are two ends of the plastic sheet gathered and tied against the stem, one under the lower part and the other above the upper part.It is important that the upper cut is covered with a rooting medium because roots form from this cut.
The plastic sheet can be placed first on the stem with one end tied below the lower cut.The rooting medium is inserted slowly and the plastic wrapping is tied securely to the stem.If held by the hand, the marcotting technique can be used with any rooting medium.
It is tied to another branch or a stick attached to the parent plant to prevent it from breaking.
The rooting medium can be held by broken or halved pots, cans or plastic cups in stems which are more or less erect.A support is needed for big containers.
A container can be made with a relatively thick plastic sheet with the bottom gathered and tied just below the lower cut and the top expanded to form a shape like a funnel.The sides are stapled or piercing with a thin stick.
This funnel-shaped container can be made out of thick leaves from plants like Ficus and croton.The sides are secured with a stick.The rooting medium is kept moist by regular watering.
When a lot of roots have developed, the roots are severed from the parent plant.When touched, the rooting medium becomes rough.New shoots will have sprouted from the portion of the stem immediately below the rooting medium.This occurs at least 15 days after marcotting.
The shoot is put into a container.Factors such as the size of the shoot, the rooting medium, and the amount of roots will affect the intensity of care.The newly potted marcots are kept under high humidity and partial shade.
Try it on croton or balete.You will soon realize how easy it is to grow plants by marcotting.
Budding is a method of asexual propagation.Basic procedures are discussed.
The method of plant propagation called air layering is described and given some advantages and disadvantages.
