• The cutting process involves the cutting of the stem part of the plant and grown in the soil, the stem develops roots and leaves and new plants are grown through this way.
• The layering process occurs when from the same parent stem many branches develop each stem develop a root system and live as an individual plant.
• The grafting is the process through which a stem is cut and tied over other plant stem this way the quality of both plants will retain in a single plant.
