What are the differences between mound layering and air layering

Answer» Aerial layering:1. A healthy branch of the plant is selected, and a girdle is made just below a node.2. The girdle portion is covered with moist moss plants, cotton or polythene sheet to prevent evaporation of moisture.3. An earthen pot with a hole at the bottom is hung from a branch above it to ensure a continuous supply of water.4. This portion is then left undisturbed till adventitious roots appear from above the girdled area.5. When healthy roots appear through the polythene sheet, the layered shoot is separated from the mother plant.Examples: Croton, climbing rose, guava, orange, litchiGround/Mound layering:1. A branch near the ground is bent downwards so that it touches the soil.2. Under a node on the basal side, a cut is made to form a tongue.3. With the help of a small piece of wood, the two cut parts are kept apart.4. The tongue part is then covered with soil some distance from the tip.5. A stone is placed on the layered portion in position or it is covered with soil.6. Water is provided whenever required.7. After few days, the part that is under the soil develops roots. The layered part can then be separated from the parent plant and grown separately.Examples: Ipomea, rose, jasmine, mango, litchi, grapevine
