There are two options for plant propagation by layering. Each consists in the fact that the new plant gets its own roots, being not cut off from the mother plant (otherwise it will be cuttings). While the cuttings are taking root, the mother plant provides them with nutrients.
The first method consists in deflecting and bending the lateral shoot from the bush to the ground, and re-rooting it. Those. if the bush has flexible or herbaceous shoots, one of them can be bent to the ground in the same pot or put the pot next to it. Pin the cut to the ground with a paper clip or press it with a pebble, do not cut off the mother plant until roots are formed. Under the influence of soil moisture and stagnation of sap flow, due to the bending of the shoots, they take root.
Thus, you can root philodendrons, tradescantia, ficus pumila, cissus, ivy, citrus fruits, roses, rhododendrons, etc. This method is quite rare in indoor floriculture, because most plants that can be propagated in this way are easily rooted by cuttings. It is best to carry out reproduction by layering in the spring on annual shoots. In this case, the middle part of the branch to be diverted should be submerged in the ground, and the upper part raised above it. If it is necessary to root woody shoots (for example, citrus fruits), then in the place where the branch will be immersed in the ground, an incision in the bark is made on it towards the top of the branch, and the layering is tied to a peg for strength.
Some flowers, such as davallia, form layers on aerial roots - "hare" legs (photo above). They take root very easily. A cut piece of root with layering is placed on the surface of the moistened soil and pressed with a pebble. Shaggy roots are not sprinkled with earth, otherwise they can rot. The pot is placed in a bag and ventilated twice a day for 30 minutes.
The layering method is applicable on plants with thick, stiff trunks (aralia, ficus - benjamin, rubber, dracaena), which cannot be bent to the ground, and for some reason cannot be cut, they are taken in an upright position. To do this, an incision is made on the branch that they want to take away or the bark is removed in the form of a narrow ring, a width of 5-7 mm is enough. Below this, a plastic bag or a transparent plastic cup is fixed around the trunk. The bag is filled with loose peat soil or sphagnum moss, which should be kept moist all the time. Then the bag is fixed up the trunk. After rooting (the roots become visible through a transparent bag or the walls of the cup), the incised branch - layering, is cut off. The remaining lower part can be used for cuttings. This breeding method is often used,when the lower part of the trunk of the plant is bare, and it has lost its decorative appeal, and the crown is beautiful, but too large to root as a cutting.
